1.0 EXECUTIVE SUMMARY

The following report is to update the engineering model of the electrical system at the James J.

Peters VAMC in Bronx NY. The previous report was written by Schweitzer Engineering Laboratories’ Government Engineering Solutions department (SEL GES) in 2015. The model that was updated in 2015 was the basis of this evaluation. This report will re-evaluate the Single Line Model of the campus along with calculate and report on the Load Flow and Generation Capacity, Short Circuit, System Coordination and finally Arc Flash Analyses.

Along with a technical analysis this report will review the installed equipment for code, system integrity, and “health” of the installed system.

The final goal of this report is to review the as found condition of the equipment during the visual inspection portion of the project. During this visual inspection the system was photographed and reviewed for code compliance, in installation, upkeep and system integrity. The deficiencies from the previous SEL report in 2015 was also reviewed to see if they have been completed or not.

DESCRIPTION OF THE ELECTRICAL SYSTEM

5kV System

The site is served at four independent locations by Consolidated Edison, Inc. (ConEdison). The first two points of service supplies transformers 1X-32 and 1X-21. Each feed consists of one 3000kVA, 13.2kV // 4160V transformer supplying power to a 5kV bus.

The third and fourth points supplies transformers 1X-28 and 1X-29. Each of these feeds also consist of one 3000kVA, 13.2kV // 4160V transformer supplying power to a 5kV bus.

The four 5kV buses are backed up by a pair 3575kVA, 4160V Diesel Generators. Each generator has its own synchronized bus and ties all four 5kV supply busses together via a coordinated breaker system. This system allows any of the four 5kV buses to be fed loads individually or tied through the generator’s sync bus. The generators are also synchronized to back up the system independently or run along with the utility for support.

480V System

The “Main Secondary Switchgear” (MSS) Networks feed the majority of the 480V loads across the site via a bus duct network within the main hospital and research building.

Each of the four above mentioned 5kV buses supplies power to five 2500kVA, 480VAC transformers one 500kVA and one 300kVA transformer. The 2500kVA transformers feed 480VAC buses that are broken into two MSS networks on the north and south ends of the campus and one 480V switchgear dedicated to CHILLER 3.

The MSS are two double ended 480V switchgear that feed the bulk of the 480V load on the site.

The third “network” is a single ended feed to a dedicated switchgear for the 480VAC Chiller in the powerhouse.

REP-21041-06-001 REV. 1

September 15, 2021

Encorus Project # 21041

The 5kV feed to the 500kVA transformer is for the “MDS” switchgear in the Community Living Center (CLC). The MDS feeds the CLC, chapel and pool.

The final 5kV feed is tied to the primary side of the MDS switchgear and feeds a 300kVA transformer for the Fisher housing areas.

Emergency Systems

The emergency system is broken between Equipment, Critical and Life Safety system per the NEC 700 requirements.

NDP – Normal Distribution Panel EED - Emergency Equipment Distribution CPD- Critical Power Distribution LSD- Life Safety Distribution

Each of the MSS Networks have their own NDP (Normal Distribution Panel). These panels feed the normal power side of Automatic Transfer Switches to LSPD (Life Safety Distribution Panel), CPDP (Critical Power Distribution Panel), EEDP (Emergency Equipment Distribution Panel).

The emergency side of the transfer switches are feed from five generators connected to two generator buses. Network #1’s generator bus (South side) has generators G1, G3 and Network #2’s bus (North side) has G2, G4 and G5. The two generator buses are connected with tie breakers.

Refer to the Single Line drawings in Appendix <A> for details.

2.0 METHODOLOGY

The update to the electrical system started with a review of the existing drawing and SKM models and previous SEL study. These documents were reviewed and set against the most up to date drawings to identify areas upgraded from the last study.

A site investigation was then conducted to photograph, update the drawings and document the changes to the site. The photos can be found in the BIM site connected with this project. The changes have also been outlined and shown on the Single Line drawings see appendix <A>.

The updates to the site have been entered into the latest edition of SKM ver. 9.0.1.1 And a new version of the Single Line Diagrams has been developed and added to this report.

3.0 RESULTS

See attached appendices for one-line diagrams, Load Studies, Short Circuit Studies and an arc-flash input/output matrix. The following results show where areas of deficiency are in the current system as it was found in our investigation.

These areas will be reviewed and catalogued for engineering support and potential upgrades depending on the results shown below.

Load Study

The voltage drop analysis evaluates the level of voltage drop at each point in the system as compared to that allowed by the 2020 National Electrical Code (NEC).

See Appendix (B)

- Example Load Flow Summary

The Load Flow Calculator will show each bus in the model as in or out of service and compare the buses rated design voltage against the calculated loaded voltage. From this calculation is determined the % Voltage Drop at each bus. This is displayed in both %VD and PU (per unit) value.

Design Settings

The load study is based on a global demand load for each voltage level (i.e., 13.2kV, 4.16kV, 0.48kV, and 0.28kV). For this study the global demand was set at 100% for the 13.2kV level, 20% for the 4.16kV level, 20% for the 0.48kV level, and 25% for the 0.28kV level.

Currently, ConEdison is replacing transformer 1X28, which has caused an increase in the voltage drop throughout the system. To show this, we provided a load study with the 1X-28 transformer in

REP-21041-06-001 REV. 1

September 15, 2021

Encorus Project # 21041 and out of service. Note: When placing transformer 1X28 back in service we estimated the transformer’s impedance from the other existing transformers.

Results and Worst-Case Load Scenarios

• Results with 1X28 out of Service

This is the current running condition and also the worst-case utility scenario. The results shown in Appendix (B) show significant voltage drop (greater than 5%) in areas across the south side of the campus without the voltage support of transformer 1X28.

The NEC recommends that the maximum combined voltage drop for both the feeder and branch circuit shouldn't exceed 5%. Excessive voltage drop in a circuit can cause lights to flicker or burn dimly, heaters to heat poorly, and motors to run hotter than normal and burn out. This is because the load has to work harder with less voltage pushing the current.

Our recommendation would be to bring transformer 1X28 in service when available. Until this is available, if any of the above conditions are seen in the hospital, shedding some of the load or tapping up supporting transformers may be temporarily necessary.

Results with 1X28 in Service

Note: A Common impedance has been estimated for 1X28 to generate these results. This load shows the “normal” running conditions once 1X28 is back in service. The summary of these results is included in Appendix (B).

With transformer 1X28 back in service the model shows the high voltage drop shown on the south side of the campus lowers below 5% in most cases. In the Research Building,105, the model stills shows a higher than desirable voltage drop. This may be due to over-estimation in the modeling but if the above negative conditions are still in the hospital areas the loads and voltages should be measured and monitored so corrective actions can be made.

• Results on 4160 Generation Only – A bus summary has been added to show the voltage drop when the Utility is out of service and the 4160V Generation backs up the hospital. As expected, voltage sag is very high in this temporary condition, however no bus’s fault in this scenario which shows the current emergency generation is sufficient for the current load.

Short Circuit Analysis

The short circuit analysis evaluates the adequacy of the electrical system equipment to withstand or to interrupt the calculated maximum available short circuit current at its location.

REP-21041-06-001 REV. 1

September 15, 2021

Encorus Project # 21041

See Appendix (C)

- Example Short Circuit Study

The short circuit report summarizes the maximum available fault duties, using SKM PTW Comprehensive Short Circuit Study setup, when the system is being supplied by the utility.

The types of unsymmetrical faults occurred due to the short circuit conditions, namely single phase or line to ground (SLG) fault, phase to phase (LL) fault and double line to ground (LLG) fault.

A single line-to-ground (LG) fault is one of the most common faults and experiences show that 70-80 percent of the faults that occur in power system are of this type.

A line-to-line fault occur when a live conductor comes in contact with another live conductor.

In double line to ground faults, two lines come into the contact with each other as well as with ground.

A Symmetrical or balanced three phase fault is where all three phase are faulted together. This is the most severe but also the least likely, happening in about 2% of total system faults.

Because of its severity, symmetrical three phase fault analysis is necessary for determining the size of a circuit breaker for largest short circuit current.

The results found in Appendix C are broken up by bus, contributing branch circuits and available Symmetrical and Asymmetrical fault categories as described above.

Fault Scenarios

• 1X28 out of Service

A summary of this scenario has been included as the current case in the current service of the campus.

REP-21041-06-001 REV. 1

September 15, 2021

• 1X28 in Service and Normal Utility in Service

A summary of this scenario has been included as the “normal” case once the 1X28 Transformer is back in service.

Note: A Common impedance has been estimated for 1X28 to generate these results. This summary was added to show the fault contributions when normal operating conditions are returned.

Short Circuit Results and Equipment Ratings

The results of the short circuit analysis are used to feed the available energy for the Arc Flash study.

The second purpose of these results are to compare the available fault current to the protection devices interrupting rating. This will determine a devices ability to withstand a short circuit or overload energy. This is shown in SKM as the device’s equipment rating.

Equipment Ratings

This appendix is a list of the buses including Switchgear, Motor Control Centers, Distribution, panel boards and main protective devices. The purpose is to compare the buses and protective devices rated voltage, ampacity and interrupt rating versus the calculated load and available fault current. If the available fault current is larger than the buses’ fault interrupt rating it is flagged as deficient and our recommendations for upgrade or replacement.

The equipment study shows all the equipment ratings meet or exceed the short circuit fault rating.

The equipment that was failed from the 2015 study has been replaced and the new equipment meets the short circuit requirements.

Protective Device Coordination

The protective device coordination study determines the suggested settings and ampere ratings for all electrical power system protective devices in order to achieve the desired system protection and electrical service continuity goals.

Included in this section are coordination curves for the major buses within the hospital electrical network. The complete TCC results of the Coordination study can be seen in Appendix D. Listed below are TCC examples where miscoordinations were found and suggestions to improve the system coordination.

• TCC NAME – EDSN / GEN4 / ATS 6 (North side Generator Bus)

The Generator and EDSN mis-coordinate. The large clear time of the molded case Siemens breaker overlaps the generator bus breaker. The generator breaker can be slightly adjusted to improve this overlap of these breakers (see the charts below)

The Arc Flash Incident Energy at bus MDS is unaffected by this change.

• TCC NAME –In places on the Main Distribution Buses MSS-1 and MSS- 2 fused disconnects are the installed in place of Main Panel Breaker. The fuses typically either mis-coordinate with the main breaker or are set so high they are oversized for the application. In the examples below The two breakers are in much better coordination.

As these serve the same branch feeder they do not need to be replaced we are pointing out

- The different applications within the same system

- That if the fuse opens up the downtime is typically longer as the fuses need to be replaced

- The coordination of the breakers is much better and easier to maintain.

Our recommendation is that the switch over gets completed throughout MSS-1 and 2 as the breakers are easier to coordinate and will lead to fewer nuisance outages.

REP-21041-06-001 REV. 1

September 15, 2021

Encorus Project # 21041

• TCC NAME – NQ Dist Pnl (The feeder to the Chapel Building)

The breaker is very limiting to the full load ampacity of the transformer feeding it. This may have been done intentionally due to the reduced loading in the area. No action is required we are pointing out a possible nuisance point if the load in the area is ever increased.

• TCC NAME – EDSS / EDSN (The 480VAC Generator Buses)

The TCC Curves shown in this report were from the existing data and could not be verified during our initial inspections because the generators could not be run.

The TCC settings show proper coordination and should be field verified to ensure these settings are still accurate when possible.

• MSS 1 and MSS 2 Bus System

The main feeders for building 100 are feed from federal pacific busways out of MSS1 and MSS2.

These busways go from the ground floor all the way to the top of the hospital and are tapped at each floor in the designated electrical rooms for their floor. These taps are typical made with 400 or 800A fused disconnects which then feed main distribution panels in the electrical rooms. These main distribution panels are sometimes MLO (Main Lug Only) which means there is no main circuit breaker in the panels and these panels rely on fuses in the disconnect to protect the panels. In some cases, these fuses do not exist or do not coordinate with the panels or the busway circuit breakers in MSS1 and MSS2. This is a code violation and dangerous condition where a fault in these panels would build until the circuit breaker in the MSS would have to open the busway to interrupt the fault.

When the distribution panel includes a main circuit breaker, the coordination is significantly improved.

REP-21041-06-001 REV. 1

September 15, 2021

Encorus Project # 21041

To properly protect these panels our recommendation would be to add a main circuit breaker in the MLO distribution panels and coordinate them with the MSS breaker feeding the busway as shown in the chart above.

Alternatively, properly sized and coordinated fuses could be added to the fused disconnect switches to accomplish this protection scheme. However, as seen in the chart above the Main Circuit Breaker and the fuse are trying to protect the same panel at the same current and coordinating the two protection devices will be difficult or impossible.

Protective Device Coordination Results

With only the few exceptions found above the protective device coordination was found to be in order. Our recommendation would be to make the few adjustments shown above. Secondly, a single protection scheme has to be determined for the MSS busway networks and properly installed to protect the electrical floors distribution panels. Our suggestion would be to coordinate the Mains on the distribution panels with the MSS busway feeder breakers consistently throughout.

Arc Flash Analysis

Flash Evaluation is a program that calculates the incident energy and arc flash boundary for each location of the power system. The study automatically reads the short circuit duties at each bus and through each protective device. The arcing fault current through the protective devices is then calculated from the bolted fault value and used to automatically find the time duration of the arc from the time current coordination (TCC) curves. Incident energy and arc flash boundaries are calculated based on the bus 3 phase fault current and arcing duration. Clothing requirements are specified from a user defined personal protective equipment table.

Example Arc Flash Incident Energy Chart - Appendix (E)

Hazard-Risk Tables

The following table is the Hazard-Risk Table from the SKM Power Tools Arc Flash Module.

The Personal Protective Equipment (PPE) Table and is taken from NFPA 70E Informative Annex H.

The Risk-Hazard table is divided based on a range of incident energy (IE), measured in calories/cm^2 (cal/cm^2), representing the available arc flash heat energy. The threshold value of incident energy that can cause 2nd degree burns to the uncovered skin is 1.2 cal/cm^2 (citation needed, read from https://electrical-engineering-portal.com/what-is-incident-energy-caused-by-arc-flash).

The required level of PPE per incident energy level is shown below and ranges from levels 0, 3, 4, and Dangerous.

PPE level 0 corresponds to the range 0.0 to 1.2 cal/cm^2.

PPE level 3 corresponds to the range 1.2 to 12 cal/cm^2.

PPE level 4 corresponds to the range 12.0 to 40.0 cal/cm^2.

PPE level Dangerous corresponds to anything above 40.0 cal/cm^2.

Adjustments to Incident Energies - Arc Flash Analysis

Buses EDSS and EDSN have different Arc Flash incident energies depending on the number of generators running in the scenario when they fault. The Arc Flash incident energies are shown in Appendix E.

The highest incident energy levels are when all the generators and utility are running paralleled and in this case the bus cannot be worked on live. The Arc Flash labels will reflect this condition.

Network buses MSS-1 and MSS-2 have very large incident energy levels and these also cannot be worked on live. Reducing the incident energy levels of these buses is difficult due to the equipment currently installed. The currently installed breakers do not have the adjustment ranges or maintenance modes of more modern equipment. Additional equipment could be installed around MSS1 and 2 to reduce the incident energy levels but this is would require an upgrade to the Network Buses.

Alternatively, MSS 1 and 2 buses are near the end of their effective service life and cost-benefit of replacing these items with more modern arc flash equipment compared to trying to extend their life by adding equipment around them should be looked at.

The MDS bus has a high incident energy level and is near the maximum allowable limit for live work.

If it is desirable to perform live work on the MDS bus arc flash reduction breakers with maintenance mode settings or changing the primary fusing on the incoming bus would be recommended.

5.0 RESULTS AND RECOMMENDATIONS

One Line

A working set of up-to-date drawings are required by the NEC 490.48(B). The existing set of single lines are incomplete or inaccurate. One complete set of singles lines should be updated and corrected. The single lines attached to report are accurate to the panel bus level. These were used for the Arc Flash analysis but are incomplete at the branch circuit level.

Load Flow

The model results show a voltage drop greater than 5% in areas across the south side of the campus without the voltage support of transformer 1X28.

If any negative conditions as listed in the report are seen in the hospital, a more selective and detailed data collection will be required. In the short-term load shedding or tapping up supporting transformers may be temporarily necessary to help with voltage support. Bringing transformer 1X28 in service when available will also help bring up some of the voltage sag seen in the model.

Short Circuit / Protective Device Coordination

The protective device coordination was found to be mostly in order. Our recommendation would be to make the few adjustments shown in Device Coordination section. Secondly, a protection scheme has to be determined for the MSS busway networks and properly installed to protect the electrical floors distribution panels.

Arc Flash

The final evaluation of the Arc Flash model found that the majority of the buses and panels throughout the campus are in a low energy level arc flash risk. A renovation of the transformers, panelboards and main protective devices from the last study has shown improvement in many areas of the campus. A few exceptions are the MSS buses and busway system, MDS Bus and the 480 Chiller Bus. These systems should be upgraded with arc flash maintenance protection, upgraded with more modern equipment or not worked on live.

Code and Equipment Deficiencies

The panel deficiencies in section 4.0 should be addressed, these include unlabeled panels, open wireways and circuit openings, exposed busing, incorrect or missing backplates or panel faces and cluttered / inaccessible electrical spaces.
