EXECUTIVE SUMMARY

This summary report contains the results of analyses performed on the electrical distribution system for the Samuel S. Stratton Department of Veterans Affairs Medical Center in Albany, New York. The purpose of this study is to evaluate new electrical equipment provided under Phase 3 and Phase 4 for this facility. System data and necessary modeling assumptions are provided under Section 7.0.

1. Short-Circuit Analysis Perform a short-circuit study on the electrical distribution system shown in order to determine the available fault current at pertinent locations throughout the distribution system. The scope of the study includes:

• Analysis begins at the incoming 13.2 kV Switchgear, Switchboard S-22, and the Paralleling Switchgear, continues through the 13.2KV/208V transformers and Switchboards A, BA, BB, C and D, and ends at the low voltage panelboards as shown in the contract drawings.

The available fault currents determined by the short-circuit study will be used in the electrical distribution analyses.

2. Equipment Evaluation Evaluate the short-circuit ratings of new protective devices and other distribution equipment supplied by Eaton under this contract.

3. Coordination Study Develop time-current coordination plots to derive coordinated settings for new protective devices. Eaton will also review the existing system overcurrent protection and coordination at locations where the existing protective devices feed the new equipment. Where applicable, provide suggestions for improvement.

4. Selective Coordination Study Review the selection of protective devices within the portion of the distribution system required to be selectively coordinated. Utilize time current curves to verify selective coordination.

5. Arc Flash Analysis Perform an arc flash incident energy analysis per NFPA 70E on the electrical distribution system as per Eaton’s scope of work.

An incident energy analysis is defined by NFPA 70E to be a component of an arc flash risk assessment used to predict the incident energy of an arc flash for a specified set of conditions.

Albany VAMC 1-2

6. Recommendations Provide specific recommendations for improving the electrical distribution system performance and correcting any deficiencies found by the studies.

1. Short-Circuit Study Cases for normal and emergency operation are evaluated. See Section 2.0, Section 8.0, and Section 9.0 for more information.

2. Equipment Evaluation The Equipment Evaluation is based on the power system worst-case short-circuit current configuration. The short-circuit ratings of protective devices and other distribution equipment are evaluated in Section 2.0, Table 2.1.

In summary of Table 2.1, all Eaton equipment included in this study has passed the equipment evaluation.

The short-circuit withstand ratings of low voltage disconnect switches are not evaluated in this study. Care should be taken in order to ensure that these devices are applied within their UL listed short-circuit withstand ratings. The typical withstand ratings for Cutler-Hammer disconnect switches (safety switches) range from 10,000A to 200,000A for certain fused types.

See Section 2.0 for detailed analysis and evaluation results.

3. Coordination Study The time-current coordination plots of the protective overcurrent devices are shown in Section 3.0. In developing the device settings, consideration was given to the isolation of faults, protection of cables, and protection of transformers.

Efforts were made to provide the best coordination possible with the protective devices supplied under this contract and the existing protective devices. It should be understood that selective coordination between two instantaneous trip units cannot be achieved for fault levels above the instantaneous pickup of the upstream device.

There is some overlapping of curves that cannot be avoided.

All of the adjustable low voltage electronic trip and thermal magnetic circuit breakers should be tested and adjusted according to the recommended settings given in Section 5.0.

4. Selective Coordination Evaluation All protective devices beginning at Switchboard S-22 and continuing down through the emergency loads fed from Automatic Transfer Switches ATS # ADLS, ATS # AEC, ATS # BCLS, ATS # BEC, ATS # CEC, and ATS # DEC have been shown to selectively coordinate (Normal Side of ATS # ADLS, ATS # AEC, ATS # BCLS, ATS # BEC, ATS # CEC, and ATS # DEC Automatic Transfer Switches) to 0.1 seconds.

Furthermore, all protective devices beginning at the 1.25 MVA generators and continuing down through the emergency loads fed from Automatic Transfer Switches ATS # ADLS and ATS # BCLS have been shown to selectively coordinate

Albany VAMC 1-3

(Emergency Side of ATS # ADLS and ATS # BCLS Automatic Transfer Switches) to

0.1 seconds.

In addition all protective devices beginning at the 1.25 MVA generators and continuing down through the emergency loads fed from Automatic Transfer Switches ATS # AEC, ATS # BEC, ATS # CEC, and ATS # DEC have been shown to selectively coordinate (Emergency side of ATS # AEC, ATS # BEC, ATS # CEC, and ATS # DEC Automatic Transfer Switches) to 0.1 seconds.

See Section 4.0 for further information regarding additional selective coordination details.

5. Protective Device Settings Settings for the protective devices supplied by Eaton should be set as shown and recommended in Section 5.0.

Each entry references a coordination plot number found in Section 3.0. The referenced plot illustrates the coordination of the listed device with the relevant “upstream” and “downstream” protective devices.

The relay settings for the main relays that feed Switchboards A, B, C, and D, and S- 22 were taken from the previous study by GE Energy Industrial Solutions. No changes to the existing relay settings is required.

New settings for four feeder breakers in the Paralleling Switchgear have been recommended by Eaton in this study. The designations for the four breakers are EDP-MAIN-EQ, EQ-EDP, CR-EDP, and LS-EDP. The new recommended settings have been highlighted in the settings tables in Section 5.0.

6. Arc Flash Incident Energy Analysis Details of the arc flash incident energy analysis are shown in Section 6.0. Please note for this study, the arc flash hazard has been calculated by performing an incident energy analysis. The results of this study can be used by qualified workers to determine the arc flash boundary and select appropriate arc flash PPE as part of an overall arc flash risk assessment. NFPA 70E Table H.3(b) provides guidance on the selection of arc rated clothing and other PPE based on the results of an incident energy analysis. It is the responsibility of the employer and qualified person(s) to conduct an overall arc flash risk assessment as detailed in NFPA 70E-2015 Article

130.5 before the commencement of work on electrical equipment. The risk associated with performing energized electrical work will vary based on the work being performed as well as the condition of the equipment and other factors that can be best determined by a qualified person in the field.

According to NFPA 70E Article 130.7(A), Informational Note 3, it may be necessary to place greater emphasis on establishing an electrically safe work condition when working within the limited approach boundary at locations where the incident energy exceeds 40 cal/cm2. The greater emphasis is due to additional hazards created from blast pressure associated with a possible arc. The PPE requirements outlined in NFPA 70E only address the thermal hazards associated with arc flash events and do not provide protection against other possible physical trauma resulting from an arc flash event. See NFPA 70E Article 120 for details on establishing an electrically safe work condition.

Albany VAMC 1-4

In summary, there are locations that have incident energy levels that are above 40 cal/cm2, refer to Section 6.0 for detailed information.

a) Reducing Incident Energy Levels: The calculated incident energy at a particular location is dependent on three main factors: short-circuit current, distance, and time. These three factors directly affect the incident energy in the following manner:

Short-circuit current: The short-circuit current for a given power system is dependent on the system impedance and source fault current, and cannot be easily reduced.

Distance: IEEE Std 1584™ provides a table with typical working distances.

Increasing the working distance reduces the amount of incident energy that reaches the worker; however it becomes difficult to perform many work tasks with an increased working distance, therefore, this is not an optimal solution for most cases.

Time: The incident energy decreases when reducing the exposure time of the arc. This exposure time is directly related to the clearing time of the protective device(s) which feed the fault location.

Based on the preceding summary, arc flash mitigation techniques are most effective and feasible when they involve reducing the arc exposure time. In many locations, the setting of the protective device can be adjusted in order to decrease the interrupting time, resulting in a decreased incident energy.

However, in this study, settings for protective devices have not been adjusted to reduce incident energy if the chance of nuisance trips within critical circuits is introduced.

The other option involving reducing the arc exposure time is to consider equipment modifications and upgrades. Several solutions include upgrading trip units, installing “maintenance switches”, and using relays with multiple settings groups. Each specific location needs to be analyzed to determine which reduction method is best employed.

b) NFPA 70E requires that the arc flash analysis be updated:

NFPA 70E requires that the arc flash analysis be updated:

• Every five years (at minimum)

• When the electrical system is modified, including renovations, additions, or subtractions to the system

7. Testing and Preventative Maintenance The 2015 edition of NFPA 70E Section 205.3 and 205.4 requires that regularly scheduled testing and preventative maintenance be performed to ensure that the electrical distribution equipment continues to perform at an optimum level. Testing should entail primary injection testing of all circuit breakers to verify proper tripping ranges, contact resistance testing, insulation resistance testing and complete switchgear and transformer cleaning and inspection. Refer to NFPA-70B for specific types of testing and interval recommendations. The industry generally performs breaker testing every 3-5 years.

Albany VAMC 2-1

SHORT-CIRCUIT ANALYSIS

The short-circuit study determines the fault currents that flow in the system during various fault conditions. A system model was created using SKM Systems Analysis software. The calculated fault currents are used in the device evaluation and coordination studies. See Section 8.0 and Section 9.0 for the computer generated input data and output data. NEC-2014, Article 110.24(A) requires that service entrance equipment is labeled with the following pieces of information:

• Maximum available fault current

• Date on which the fault current was calculated Article 110.24(B) adds that if there is a modification that may change this fault current value, it must be recalculated. The field marking must be updated to reflect the new value of maximum fault current.

Separate “Z” (complex), “X” (reactive), and "R" (resistive) networks are used for the short-circuit analysis. Complex network reduction and the relationship E/Z are used to calculate the fault current magnitude and angle at each faulted bus. The complex equivalent circuit impedance, Z, is calculated by the reduction of the “Z” (complex) network. The X/R ratios calculated for each fault condition are based on the separate reduction of the X and R networks. These X/R ratios are used for the calculation of fault duty multipliers, to evaluate the short-circuit ratings of system components.

The software is capable of generating three types of short-circuit reports for both balanced (three-phase bolted) and unbalanced (line-to-ground) faults. The reports that are generated depend on the system that is being evaluated.

The three types of short-circuit reports are:

• Fault Report (for low voltage)

• Momentary Duty Report (for medium voltage)

• Interrupting Duty Report (for medium voltage)

1. Fault Report The fault currents reported in the “Fault Report” are applicable to low voltage devices and components. The fault currents calculated in this report are based on the contribution data derived from IEEE Std C37.13™. The fault currents are calculated as follows:

• Motor and generator subtransient reactance values (Xd”) are adjusted per the first cycle duty multipliers described in IEEE Std 141™.

• The complex equivalent circuit impedance, Z, is calculated by network reduction of the “Z” (complex) network.

• The momentary symmetrical current = E/Z.

• The X/R ratio is equal to the equivalent circuit reactance, X, divided by the equivalent circuit resistance, R. As discussed above, X is calculated by the reduction of the “X” (reactive) network and R is calculated by the reduction of the “R” (resistive) network.

Albany VAMC 2-2

Multiplying factors are determined, and used to adjust the calculated symmetrical fault current. The adjusted current is used to evaluate low voltage protective devices. Low voltage output algorithms and output reports reflect NEMA AB-1 molded case breaker de-rating multipliers. Breakers are de-rated for circuits where the power factor is lower than the NEMA test circuit (higher X/R ratio). The multipliers adjust the symmetrical fault current to the value associated with the systems fault point X/R ratio. The adjusted value listed on the report may then be compared directly with the manufacturer's published interrupting rating.

The objective of the short-circuit analysis is to calculate the maximum short-circuit currents produced by balanced three-phase and unbalanced faults at each bus shown on the one-line diagrams.

1. Short-Circuit System Model The system was modeled for worst-case fault currents. Short-circuit currents were calculated for a three-phase bolted fault and single-line-to-ground fault at each bus shown on the study one-line diagrams.

a) Evaluated Short-Circuit Cases:

The following short-circuit study cases were evaluated:

• Study Case No. 1 – Utility Source Online and Generator Source Offline

• Study Case No. 2 – Generator Source Online and Utility Source Offline

The purpose of the equipment evaluation is to compare the maximum calculated short-circuit currents to the short-circuit ratings of protective devices. The comparison is made in order to determine if the device can interrupt or withstand the available fault currents of the electrical system to which the device is applied, as required by NEC Articles 110.9 and 110.10. The device evaluation follows the evaluation procedures outlined in IEEE Std C37.13, IEEE Std C37.010, IEEE Std C37.5, IEEE Std C37.41™, IEEE Std 1015™, and applicable ANSI, NEMA, and UL standards.

The results of the short-circuit equipment evaluation are summarized in Table 2.1.

The tables indicates “Bus I.D.” (corresponds to bus designations used in the one-line diagrams, “Manufacturer”, “Status” (Pass, fail, unknown, or marginal), “Type” (equipment category), “Equip Volts”, calculated short-circuit duty, the equipment short-circuit rating, the series rating (if applicable), and the maximum duty rating.

The maximum duty rating is calculated by:

RatingCDeviceS dutyCS

All short-circuit current values are reported in units of kA.

For low voltage devices the calculated short-circuit duty is reported under “Calc Isc (kA)" and the device short-circuit rating is reported under "Equip Isc (kA)". The calculated duty has been adjusted accordingly per the system X/R and device test X/R.

Information used in modeling the power system to provide conservative, worst-case results is listed in Section 7.0. The results of the short-circuit analysis, including calculated branch contributions, are provided under Section 9.0. The one-line diagrams with referenced bus identification are included in Section 12.0.

PROTECTIVE DEVICE COORDINATION STUDY

The protective device coordination study determines overcurrent protective relay and circuit breaker settings in order to provide an optimal compromise between protection and selectivity.

Using the appropriate maximum fault currents, the time-current coordination curves were plotted as operating time versus current magnitudes to show protective device tripping and/or clearing characteristics and coordination among these devices.

Consideration was given to provide both selective isolation of faults and maximum protection of equipment such as cables, transformers, motors, etc.

To achieve the optimum protection and selectivity, the following guidelines were followed throughout the study:

1. Ideally, the settings of any overcurrent device should be high enough to permit the continuous full-load operating capacity of the cables and the equipment they supply, and to ride through system temporary disturbances such as in-rush current. On the other hand, the settings should be low enough to provide overload and short-circuit protection under minimum fault conditions.

2. Considering any two protective devices in series:

• The maximum available fault current at the downstream device determines the upper limit of the coordination range between these two devices.

• The minimum available fault current at the downstream device or the pick-up setting of the upstream device determines the lower limit of the coordination range.

• Series instantaneous devices do not coordinate unless there is sufficient impedance between the two devices.

• When plotting coordination curves, certain time intervals must be maintained between the curves in order to ensure correct selectivity. These time intervals vary, depending on the device types. In general, however, the following must be taken into consideration when determining the appropriate time separation interval: Breaker clearing time, relay tolerances, induction disk over-travel, and a reasonable safety margin for error.

Protective device coordination was performed in accordance with IEEE Std 242™.

Minimum guidelines for equipment protection, as outlined in the National Electrical Code (NEC) and applicable standards of the American National Standards Institute (ANSI), were followed.

Please see Section 7.0 for a complete list of data and assumptions that were used in modeling the power system to provide conservative, worst-case results. Please note that complete information regarding the system model used for the computer simulation is included in Section 8.0.

As shown on the time-current plots, each device curve is tagged with an arrow and label referencing its location on the plot's individual representative one-line diagram.

This label also references the device to its specific manufacturer information, including ratings and settings, as indicated in the text box on each plot. The device time-current characteristics are truncated at maximum through-fault current for a downstream fault.

Efforts were made to provide the best coordination possible with the protective devices supplied under this contract. Areas where breaker trip curves overlap indicate areas of possible non-selective breaker operation. Where possible, efforts were made to reduce non-selective breaker operation while maintaining adequate system protection. In some cases, because of device limitations, little can be done to improve device selectivity. Such device limitations include the fixed operating characteristic of a fuse, the built-in instantaneous or instantaneous “over-ride” elements of molded case circuit breakers, and the limited instantaneous trip range of trip units with an instantaneous trip function.

In cases involving redundant protective devices, non-selective breaker operation is of little or no concern. Protective devices are redundant if, regardless of which device opens, the same system outage occurs. Often, in order to improve overall system protection and coordination, redundant devices are intentionally set to overlap (i.e.

non-selectively coordinate with) one another.

Adequate coordination is achieved using the recommended protective devices, with settings and ratings as listed in Section 5.0. The recommended adjustments would maximize coordination in an attempt to allow the various downstream devices to isolate faults without operation of the upstream devices. Although instantaneous trip devices provide the highest degree of protection, when applied in series they compromise selectivity at high-magnitude fault currents.

The 800A type MDL feeder breaker in Panel 13-233A coordinates with the downstream 200A type EDS breaker in panel 13-233B and all other downstream panels.

The 800A type MDL feeder breaker in Panel 13-238A coordinates with the downstream 200A type EDS breaker in panel 13-238B and all other downstream panels.

Note that phase coordination for circuit breakers downstream of the generator switchgear was based on the assumption that all three generators are online. To account for the current division amongst the three generators, the curves for the generator-mounted breakers and generator main switchgear breakers in the generator switchgear are multiplied by three (in the current domain) to account for only 1/3rd of the fault current flowing through each circuit breaker. This shifts the time-current curves for the generators, and illustrates the actual coordination during a fault with all three generators online.

Refer to the following pages for the plotted coordination curves, which graphically indicate the degree of selectivity and protection obtained.

In some cases, a single time-current curve may be applicable to several locations in the system, where each location utilizes substantially similar devices, and serves similar loads.

The following list references the attached time-current curves for this report.
