1. Introduction

This report documents the results and recommendations for the short circuit, protective device coordination and arc flash evaluation for the electrical power distribution system at Rehabilitation of Water Wells Commission 15 and Commission 18, Long Beach, CA. All calculations were performed using Power*Tools for Windows Software version 11.0.0.1 published by SKM System Analysis.

1.1 Major objectives

Evaluate new protective device short circuit ratings in comparison to the calculated short circuit current.

Recommend settings for all protective devices under the scope of this project.

Identify incident energy levels and what level of personal protective equipment (PPE) is required for safe energized work.

Note area of deficiency and make general recommendations for corrective measures to improve electrical distribution performance. The scope of our study is limited to recommendations only. We are not responsible for any issues arising from design errors.

1.2 Input data and assumptions

Utility fault levels are per SCE indicated value of 30000A.

1.3 Executive Summary

All protective devices are properly rated. More detailed calculations in Appendix 1.

Good coordination is achieved with recommended settings.

2 Analysis Description

2.1 Short Circuit Analysis

The short circuit calculations were made utilizing Power*Tools for Windows software.

The calculation procedures are based on recommendations included in ANSI standards C37.13.

The A_FAULT module of Power*Tools module used for the analysis uses with the ANSI/IEEE C3713 standard for calculations of fault currents. This analysis differs from a classical short circuit calculation in that it addresses the initial fault current that is asymmetrical and has a DC offset. The initial current asymmetry can last up to several cycles and is seen by the short time and instantaneous trip components in circuit breakers.

A fault can generate three types of short circuit report

Fault report – mainly for low voltage Momentary duty report – for medium and high voltage evaluation Interrupting duty report - for medium and high voltage evaluation

In the practice the fault currents are not purely symmetrical. If the system is more inductive, measured by the system X/R ratio, the more asymmetrical the fault current can be. If the calculated value for X/R exceeds the test X/R ratio, then the increased asymmetrical value has to be taken into account when circuit breaker rating is evaluated.

Interrupting capability of the protective devices can be expressed in self or series rating.

Self rating is typically the manufacturer`s nameplate. If the calculated short circuit current exceeds this rating, protective device can fail during operation.

If one or more devices in series are tested combination, for fault levels that exceed the rating of device, simultaneous operation can limit the current to a level below the protective device self-rating. When series rating is used, the National Electrical Code (NEC), Section 110-22, requires that equipment be field marked to indicate the equipment has been applied with a series combination rating. The marking must be legible to personnel who work on the equipment.

For the medium voltage equipment evaluation two components are used: momentary and interrupting ratings. ANSI allows a simplified momentary rating calculation of 1.6 times the symmetrical fault duty.

There can be a several scenarios for short-circuit available current (based on different sources) and the worst-case scenario is used to verify a proper protective devices rating.

2.2 Protective Device Coordination Study

The main goal for protective device coordination study is to provide an optimal compromise between the desired system protection and system continuity goals. For the maximum system continuity, the protective devices have to be selected and adjusted so that only overcurrent protective devices nearest to the fault open and isolate the fault.

The PTW Captor module was used for all analysis in this report. The TCC are plotted on a log-log graphs which represents device operating versus current.

Lack of the selectivity mainly occurs when the devices are not adjustable or where there are a large number of devices in series. For the high-level faults, typically in instantaneous region of protective device characteristic, the lack of selectivity between the devices in series is more common and is not usually a problem. The reason is that the most faults involve a resistance to ground and thus the smaller in magnitude.

Selectivity for the ground fault protective devices is different from the phase fault protection since ground fault devices cannot be set above the load level

Time Current Curves lack of selectivity is evaluated in section 4.2 of this report.

2.3 Arc-Flash Hazard Analysis Evaluation

The PTW Arc-Flash module used for this analysis incorporates results from the short circuit and coordination calculations to yield the arcing fault duties at locations where arc flash evaluations are to be performed and the clearing time for the protective devices nearest the location. Incident energy evaluations are used to determine the required level personal protective equipment (PPE). If the calculated incident energy is above 40cal/cm2 it is prohibited to work on the energized equipment. This information must be incorporated in the site safety manual to provide personnel with the information required by NFPA and OSHA standards. The relevant standards can be summarized as follows:

2.3.1 110-16 Flash protection

Switchboards, panelboards, industrial control panels, and motor control centers in commercial and industrial occupancies that are likely to require examination, adjustment, servicing, or maintenance while energized must be field marked to warn qualified persons of the danger of electric arc flash. The marking must be clearly visible to qualified persons before they examine, adjust, service, or perform maintenance on the equipment.

NFPA 70E-2018, Standard for electrical Safety in the Workplace, states that “employees shall wear clothing resistant to flash flame wherever there is possible exposure to an electric arc-flash”. In addition, OSHA standard 1910.269 prohibits synthetic materials (acetate, nylon, polyester, rayon or blends) unless the fabrics has been treated to withstand conditions that may be encountered. OSHA regulations represent the other major source of standards that apply to arc flash hazard. The primary regulations are in

29CFR 1910 Subparts I and S. These can be broken down into three general areas, hazard identification and PPE selection, training and proficiency.

2.3.2 1910.132 (d) Hazard assessment and equipment selection

The employer shall assess the workplace to determine if hazard present, or are likely to be present, which necessitate the use of personal protective equipment (PPE). If such hazard are present, of likely to be present the employer shall: Select, and have each affected employee use, the types of PPE that will protect the affected employee from the hazard identified in the hazard assessment; Communicate selection decision to each affected employee; and, Select PPE that properly fits each affected employee.

The employer shall verify that the required workplace hazard assessment has been performed through a written certification that identifies the workplace evaluated; the person certifying that the evaluation has been performed; the date of the hazard assessment; and, which identifies the document as a certification of hazard assessment.

2.3.3 1910.335 (a) (1) (i) Personal Protective Equipment

Employees working in areas where there are potential electrical hazards shell be provided with, and shall use, electrical protective equipment that is appropriate for the specific parts of the body to be protected and for the work to be performed.

2.3.4 1910.132 (f) Training

The employer shall provide training to each employee who is required by this section to use PPE. Each such employee shall be trained to know at least the following. When PPE is necessary; what PE is necessary; How to properly don, doff, adjust and wear PPE;

The limitation of the PPE; and, the proper care, maintenance, useful life and disposal of the PPE.

Each affected employee shall demonstrate an understanding of the training specified in paragraph (f) (1) of this section, and the ability to use PPE properly, before being allowed to perform work requiring the use of PPE.

2.3.5 1910.132 (f) (3) Proficiency & Retraining

When the employer has reason to believe that any affected employee who has already been trained does not have the understanding and skill required by paragraph (f) (2) of this section, the employer shall retrain each such employee. Circumstances where retraining is required include, but are not limited to, situations where: Changes in the workplace render previous training obsolete: or inadequacies in an affected employee’s knowledge or use of assigned PPE indicate that the employee has not retained the requisite understanding or skill.

The employer shall verify that each affected employee has received and understood the required training through a written certification that contains the name of each employee trained, the date(s) o training, and that identifies the subject of the certification.

In locations where no safe level of PPE exists, if extension tools cannot be used the equipment can only be work on in de-energized state. This condition is indicated in the data output as a "Dangerous!" condition (See Appendix 6.).

2.4 Arc-Flash Hazard Analysis According to IEEE Std 1584TM-2018

IEEE Std 1584 provides the computational formulae for calculating incident energy and arc-flash boundary. All commercial software, Power*Tools for Windows included, use equations in IEEE Std 1584 to perform arc flash calculations for voltages between 200V and 15,000V. Until recently IEEE Std 1584TM-2002 was used in all calculations. IEEE Std

1584TM-2018 has superseded IEEE Std 1584TM-2002.

The 2018 standard in different than IEEE Std 1584TM-2002 in many ways; and generally calculates lower incident energies. Some input data from 2002 model are irrelevant now; i.e. system grounding is not considered anymore: “test results did not find any significant impact of system grounding or bounding on the incident energy released by the arc.” Major novelties in IEEE Std 1584TM-2018 are model configuration and dimensions of the enclosures.

2.4.1 Model Configurations

Configuration is an important factor in determining incident IE. New configurations are introduced the 2018 standard:

VCB - vertical conductors inside a box VCBB - vertical conductors inside a box terminated in a barrier HCB - horizontal electrodes inside a box VOA - vertical conductors inside of open air HOA - horizontal conductor in open air.

The orientation of electrodes determines direction of arc plasma flow as shown in Figures G6 and G7 of the standard. Horizontal electrode orientation transmits more heat toward the person’s working on the equipment. As explained in Annex C of the standard one piece of equipment, may exhibit different configuration depending of the place arc occurs. Annex C shows the following examples:

C.1 LV drawout Switchgear Case 1: CB present but stabs not securely connected: VCBB configuration Case 2: CB not present: HCB configuration Case 3: CB present and has internal fault: VCB configuration

C.2 LV MCC

Case 1: VCB configuration, Case 2: VCBB configuration, Case 3: VCBB configuration Cases are explained in detail in IEEE Std 1584TM-2018.

C.3 NEMA 600V Panelboard Analysis in 1584TM-2018 concludes that VCBB is the most conservative configuration.

C.4 Enclosed Switch Analysis in 1584TM-2018 concludes that VCBB is the most conservative configuration.

Due to various possible configurations it is important to select the most conservative configuration for each piece of equipment while. Flash study. Comparison of different configurations is presented in https://etap.com/arc-flash/arc-flash-ieee1584-2018 .

shows HCB energy higher than VCBB energy which is higher than VCB energy. This in general follows the logic presented in the standard that horizontal electrodes direct arc plasma towards person’s torso.

2.4.2 Enclosure Dimensions

The following enclosures were either tested or validated for IEEE Std 1584TM-2018 model:

Equipment Class Enclosures size (H x W x D) 15 kV Switchgear 45” x 30” x 30”

15 kV MCC 36” x 36” x 36”

5 kV Switchgear 36” x 36” x 36”

5 kV Switchgear 45” x 30” x 30”

5 kV MCC 26” x 26” x 26” LV Switchgear 20” x 20” x 20”

Shallow LV MCC & panelboard 14” x 12” x <=8”

Typical LV MCC & panelboard 14” x 12” x > 8”

Cable Junction box 14” x 12” x <=8” or 14” x 12” x > 8”

The depth, D, of enclosure is ONLY considered in the model if all the following conditions are met. Otherwise, the depth is irrelevant.

a) V < 600 V, and

b) W < 20”, and

c) H < 20”, If all three above are true, and D <= 8’’, the enclosure is treated as shallow.

If all three above are true, and D > 8’’, the enclosure is treated as typical

Section G.9.6 of IEEE Std 1584TM-2018 provides interesting discussion on choosing the equipment enclosure sizes. In general, for voltages above 600V, using the exact https://etap.com/arc-flash/arc-flash-ieee1584-2018 enclosure sizes would provide less conservative results. However, selecting the next smaller available size from the above table will provide more conservative results. For voltages between 208 and 600V selecting next larger enclosure size from the table above will provide more conservative results. This anomaly is also explained and confirmed by figure G.35 of the standard.

2.4.3 Equipment selections for this report

Based on the above discussion, which was confirmed by other available on-line sources, and sensitivity analysis performed in PTW software, the following configurations were used in this report:

Configuration Selection:

LV SWGR – HCB

LV MCC – VCBB or VCB LV Panelboard – VCBB or VCB Enclose switch – VCBB or VCB

Enclosure Dimensions Selection:

5 < V ≤ 15 kV – (36”x36”)

2.7 < V ≤ 5kV – (26”x26”)

0.6 < V ≤ 2.7kV – (20”x20”)

0.208 ≤ V ≤ 0.6kV – (20”x20” - switchgears, 14”x12”x10” - panelboards and MCCs)

3 Discussion and Recommendations

3.1 Short Circuit Analysis

A table summarizing the ratings of the equipment analyzed versus the available fault duties is contained in Appendix 1. Complete computer output of the input data and fault cases is contained in Appendix 4&5.

All protective devices are properly rated. More detailed calculations in Appendix 1.

3.2 Protective Device Coordination Study

Good coordination is achieved with recommended circuit breaker settings.

3.3 Arc-Flash Hazard Analysis Results

The Arc-Flash incident energy calculations are based on the recommended settings. All settings MUST be successfully implemented or confirmed prior the Arc-Flash hazard labels installation.

One power system scenario was analyzed for this report:

o Utility Available

A summary table and individual data labels detailing calculations for each location studied are included in Appendix 6. At each location, the worst-case incident energy values were used to generate PPE labels. These data labels include the flash boundary and incident energy at the working distance and are designated to be posted at the location. This data is used to determine the required PPE at various distances from the location.

The NFPA 70E requirements state that the electrical system should have been properly installed and properly maintained as per the NEC, manufacturers’ recommendations, or NETA guidelines. If the system has not been properly maintained or has improperly installed equipment, this study and the guidelines provided by the NFPA 70E, as well as the proposed arc flash PPE, may not adequately protect electrical workers.

4 Glossary of terms

4.1 Short Circuit Analysis

Series ratings: A tested combination of protective devices that allow the use of protective devices in locations that exceeds the nameplate rating by operation of an upstream protective device. Operation of the protecting device limits that fault current to below the self-protected rating of the lower rated device.

4.2 Protective Device Coordination Study

Each component on the single line diagram is identified by a unique label that corresponds to the type of equipment and the equipment served by that device. For example a component designated as “CB MSB’’ is a circuit breaker that serves MSB.

Common identifiers used in these report are as follows:

TX - Transformer

FS - Fused switch

MAIN - Main device

FDR - Feeder

CB - Circuit Breaker

GF - Ground Fault (both external or internal)

TCC - Time Current Curve is a graphical representation of the operating characteristic of a portion of an electrical system

AIC - Available Interrupting Capacity

4.3 Arc-Flash Hazard Analysis Results

ATPV (Arc thermal Performance Exposure Value): A rating (in cal/cm2) given to PPE in terms of its ability to protect against the thermal energies resulting from an arcing fault. The incident energy from an arcing fault can be compared with ATVP values to determine what amount of PPE is required for safe energized work.

PPE (Personal Protective Equipment): Clothing or tools used to protect personnel from potentially hazardous condition while working.

Flash suit: A three piece multiple layer FR outfits that includes pants (with bib), jacket, and face shield with hood to offer protection in areas where arc flash levels are high. Also referred to as Blast Suit or Switchgear Suit.

Natural Fiber Clothing: Long sleeve shirts and pants made of cotton or wool. This clothing is not flame-resistant NON FR), but will char instead of melting like synthetic fibers.

Flame resistant (FR) clothing: Aramid (i.e. Dupont Nomex) or treated natural fiber (Indura or Proban) clothing of various types and weights that are resistant to ignition when exposed to flames.

Incident Energy: The thermal energy measured in calories per square centimeter (cal/cm2) seen by a person or object as a result of exposure to an electric arc.

Flash Boundary: The distance from a location to where the incident energy from an arc is less then 1.2cal/cm2. This is considered the minimum distance to unqualified personnel.

Flash Hazard Analysis; A method to determine the risk of personal injury as a result of exposure to incident energy from an electrical arc flash.

Shock Hazard: A dangerous condition associated with the possible release of energy caused by contact of approach to live parts.

Working distance: The dimension between the possible arc point and the head and body of the worker positioned in place to perform the assigned task.

Energized: Electrically connected to or having a source of voltage

Exposed (live parts): Capable of being inadvertently touched or approached nearer than a safe distance by a person. It is applied to parts that are not suitably guarded, isolated or insulated.

Electrical Hazard: A dangerous condition in which inadvertent or unintentional contact or equipment failure can result in shock, arc-flash burn, thermal burn, or blast.

Electrical Shock: Physical stimulation that occurs when electrical current passes through the body.
