EXECUTIVE SUMMARY

This summary report contains the results of analyses performed on the electrical distribution system for Dayton VA Corrections of Arc Flash Deficiencies. The purpose of this study is to evaluate new electrical equipment provided for this facility.

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

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 beginning at the incoming 69 kV utility service, continuing through the medium and low voltage substations, and ending 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.

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. 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 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.

Dayton VA Correct Arc Flash Deficiencies 1-2

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.

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 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.

In summary of the coordination study, the following recommended changes would maximize coordination while maintaining adequate protection:

• Cables CBL-126-1-10, CBL-126-1-10C and CBL-126-1-09 DISC are undersized per NEC Article 310.15. Recommend upgrading to #1/0 CU AWG.

• Cable CBL-1726 is undersized per NEC Article 240.4(D). Recommend upgrading to #8 CU AWG or using a 30A fuse.

• Cable CBL-412-1-04B is undersized per NEC 310.15. Recommend upgrading cable to #3 CU AWG.

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 4.0.

4. Protective Device Settings

Settings for the protective devices supplied by Eaton should be set as shown and recommended in Section 4.0.

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 130.5(g) 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- 2018 Article 130.5 before the commencement of work on electrical equipment. The

Dayton VA Correct Arc Flash Deficiencies 1-3 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.

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.

6. Testing and Preventative Maintenance

The 2018 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.

Dayton VA Correct Arc Flash Deficiencies 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 7.0 and Section 8.0 for the computer generated input data and output data. NEC-2017, 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) – Not Applicable

• Interrupting Duty Report (for medium voltage) – Not Applicable

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.

Dayton VA Correct Arc Flash Deficiencies 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 – System supplied from Crown source.

• Study Case No. 2 – System supplied from Tait source.

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

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.

Dayton VA Correct Arc Flash Deficiencies 2-3

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.

Information used in modeling the power system to provide conservative, worst-case results is listed in Section 6.0. The results of the short-circuit analysis, including calculated branch contributions, are provided under Section 8.0. The one-line diagrams with referenced bus identification are included in Section 11.0.

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.

Applicable requirements are summarized below.

1. Cables

Power cables require overload and short-circuit protection in order to meet the requirements stated in NEC Article 240, and IEEE Std 242. The NEC further

Dayton VA Correct Arc Flash Deficiencies 3-2 requires that the ampacity of low voltage cable (0-2000 Volts) be determined by NEC Article 310.15. Cable de-rating based upon ambient temperature and the number of current carrying conductors in a raceway must also be applied. Medium voltage cable (2001-35,000 Volts) ampacity is defined by NEC Articles 240.100(A) and 310.60.

2. Transformers

A transformer is recommended to have protective devices on both primary and secondary side in order to meet the basic protection requirements for overloads and short-circuit withstand values. However, a transformer is permitted to be protected by only a primary side device if it meets the exceptions listed in NEC Article 240.4(F).

In addition, the transformer protective devices must be able to withstand magnetizing inrush currents without tripping.

NEC protection requirements for transformers: Overcurrent devices should be selected, and settings should be recommended to provide overcurrent protection in accordance with NEC Article 450.3. Paragraph (A) specifies that transformers over 600 V comply with Table 450.3(A). Paragraph (B) specifies that transformers less than 600 V comply with Table 450.3(B).

Short-circuit thermal limits for transformers: The primary devices should be set on the basis that the transformers have short-circuit withstand capabilities as defined by IEEE Std C57.109™.

3. Motors

The motors should have appropriate protective devices to meet the basic protection requirements for overloads and fault current withstand values. In addition, the motor short-circuit and ground fault protective devices should be set to ride through motor starting current.

Please see Section 6.0 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 7.0.

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”

Dayton VA Correct Arc Flash Deficiencies 3-3 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 4.0. 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.

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.
