EXECUTIVE SUMMARY 1.0

1.1 General

This summary report contains the results of analyses performed on the electrical distribution system for the Veterans Affairs Medical Center in Battle Creek, MI. The purpose of this study is to evaluate the new additions and existing electrical system.

System data and necessary modeling assumptions are provided under Section 6.0.

1.2 Objectives

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 4.8 kV utility service to the hospital and 14.4 kV service to Building 145, the laundry building, and continues through the medium and low voltage substations, and ends at the low voltage panelboards and motor control centers throughout the campus.

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 and existing protective devices and other distribution equipment throughout the campus.

3. Coordination Study

Review the existing system overcurrent protection and coordination. Where applicable, provide suggestions for improvement. Develop time-current coordination plots to derive coordinated settings for new protective devices.

4. 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.

5. Recommendations

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

1.3 Results and Recommendations

1. Short-Circuit Study

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

VA Battle Creek 1-1 shown on the one-line diagrams found in Section 11.0. See Section 2.0, Section 7.0, and Section 8.0 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, specific equipment has failed the equipment evaluation and are considered overdutied. It is recommended that the overdutied panelboards be reviewed for breaker and/or panelboard replacement to comply with the short-circuit current ratings required.

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 Eaton 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 new and existing protective devices. It should be understood that 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 and medium voltage equipment should be tested and adjusted according to the recommended settings given in Section 4.0.

4. Protective Device Settings

Settings for the protective devices at all medium and low voltage protective devices should be set as shown and recommended in Section 4.0.

The referenced plot illustrates the coordination of the listed device with the relevant “upstream” and “downstream” protective devices.

5. Arc Flash Incident Energy Analysis

Details of the arc flash incident energy analysis are shown in Section 5.0. 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

VA Battle Creek 1-2

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.

In summary, there are several locations that have incident energy levels that are above 40 cal/cm2, refer to Section 5.0 for detailed information.

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.

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.

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

• Every five years (at minimum)

VA Battle Creek 1-3

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

6. Testing and Preventative Maintenance

The 2015 edition of NFPA 70E Section 205.3 and 205.4 requires that regularly scheduled testing and preventative maintenance is 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.

7. Predictive Diagnostics Using Continuous Partial Discharge Measurements

Eaton recommends conducting Continuous Partial Discharge measurements on most medium voltage power transformers, bus ducts, switchgear, motors, generators, terminations, and splices of transmission and distribution cables. Partial Discharge (PD) analysis is a non-invasive, online method of collecting, filtering, and evaluating PD occurring in electrical apparatus. The goals are:

• To detect partial discharges as a result failing or compromised insulation

• To analyze the partial discharge activity, and if an insulation defect is detected:

• Make conclusions as to the severity of the defect.

• Advise as to possible defect locations and possible cause(s) of the defect.

• Advise as to urgency of inspection.

• Suggest preventive measures both immediate and long term.

Electrical insulation is very important to monitor as it defines a major item in the reliability of electrical machines. Continuous Partial Discharge on-line monitoring using the Eaton InsulGard™ is the most sensitive and reliable method for detecting failing insulation. PD monitoring when used in conjunction with Eaton’s RM™ system offers customers the added benefit of prompt expert analysis and recommendation.

8. National Electric Code (NEC) 2017 Violations

• Existing feed in Building 5 from 005 MDP-1 to 005 MDP-1A is recommended to have a protective device sized up to 1,520A installed in 005 MDP-1 to protect the cable.

• The #1/0 cables from 082 BKR ATS-82-2-N to 082 ATS-82-2 and 082 ATS-82-2 to 082 EC-82 are undersized per the 200A type CA breaker feeding them. To protect the cable, it is recommended that the type CA breaker is changed to 150A or the #1/0 cables are upsized to #3/0, copper.

• Eaton recommends these cables to be field verified and either the replace and upsize the cables per NEC Table 310.15(B)(16), or change the size of the upstream protective device(s) to protect the cable. The latter recommendation may not be an option where the branch load size cannot be lowered.

SHORT-CIRCUIT ANALYSIS 2.0

2.1 General

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 7.0 and Section 8.0 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.

VA Battle Creek 2-1

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.

2. Momentary Duty Report

The “Momentary Duty Report” contains the calculated fault currents that occur during the first half-cycle of the fault. The momentary fault currents are used to evaluate medium and high voltage fuses, and the “closing and latching” capability (momentary rating) of medium and high voltage breakers. The fault currents reported in the “Momentary Duty Report” 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 reported 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.

• The momentary asymmetrical current is calculated and reported in two different ways, once as “sym*1.6” and again as “momentary based on X/R”. The “sym*1.6” value is the momentary symmetrical current multiplied by 1.6. The “momentary based on X/R” value is the momentary symmetrical current multiplied by

( )( )e RX21 2+ − π

3. Interrupting Duty Report

The fault currents reported in the “Interrupting Duty Report” are used to evaluate the interrupting rating of medium- and high-voltage breakers. The interrupting symmetrical current is calculated as follows:

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

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

• The interrupting symmetrical current = E/Z.

• The X/R ratio reported 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.

VA Battle Creek 2-2

• The calculated X/R ratio is used to determine the minimum contact parting time multiplying factors for 2, 3, 5, and 8 cycle breakers. The multiplying factors are based on IEEE Std C37.5™ and IEEE Std C37.010™ standards. The multiplying factors are applied to the interrupting symmetrical current in order to calculate the RMS short-circuit current interrupting duty for 2, 3, 5, and 8 cycle breakers. This duty is compared to the symmetrical current interrupting rating of the circuit breaker. NACD (No AC Decrement) ratios are calculated with consideration of generator "Local" and "Remote" contributions as outlined in IEEE Std C37.010™.

• Motor and generator impedance multipliers for the short-circuit calculations are summarized in the following table. This is based on the recommended combination network for comprehensive multi-voltage system calculations (from IEEE Std 141:

2.2 Objectives

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.

For closed transition type automatic transfer switches which parallel more than one voltage source, even for a short time (< 100 ms), the available fault currents of the two sources have been considered for a combined fault current value that represents the contribution from both sources. NEC Article 110.9 states that equipment which is used to interrupt a fault must be properly rated for both the nominal voltage and the available fault current at the line side of that device. Furthermore, NEC Article

VA Battle Creek 2-3

705.16 states that all fault currents from all power sources must be considered when examining the interrupting rating of a device. Location of the analyzed fault with respect to the switching devices, such as circuit breakers, was taken into consideration when determining the appropriate device interrupting current ratings.

2.3 Equipment Evaluation

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 and Table 2.2. The tables indicate “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

If the short-circuit rating of a device is not known, and/or short-circuit rating information is not available, a Minimum Required short-circuit rating is listed. All short-circuit current values are reported in units of kA.

1. 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.

2. For medium/high voltage breakers:

The calculated interrupting short-circuit duty is reported under "Calc Isc (kA)" and the breaker short-circuit interrupting rating is reported under "Equip Isc (kA)". The interrupting duty has been adjusted per multiplying factors based on the breaker clearing time and system X/R. The calculated momentary duty (i.e. close-and-latch duty) is reported under "Calc Mom (kA)".

3. For medium/high voltage fuses, switches, and motor starters:

The calculated momentary symmetrical short-circuit duty is reported under "Calc Isc (kA)" and the device's momentary symmetrical short-circuit rating is reported under "Equip Isc (kA)". The calculated momentary asymmetrical duty is reported under "Calc Mom (kA)". The device's momentary asymmetrical short-circuit rating is reported under "Equip Mom (kA)".
