I. INTRODUCTION This overview will function as a guide for the Short Circuit and Protective Device Coordination Study for XYZ Corp. The aforementioned study was performed using the relevant characteristics of the power distribution system at the subject facility as well as the specific characteristics of the protective devices and other components of the system.

II. SHORT CIRCUIT STUDY GENERAL INFORMATION The primary reason for performing a Short Circuit Study on a power system is to calculate the available short circuit (fault) current at each bus location to facilitate the selection of protective device interrupting ratings. A protective device must be able to interrupt the available short circuit (fault) current (at its location in the power system) therefore the protective device must have an interrupting rating equal to or greater than that available short circuit (fault) current. The three phase symmetrical RMS fault current (balanced fault) is typically considered to be the maximum available fault current and hence is usually used as the basis for the selection of protective device interrupting ratings. The other major reason for performing a Short Circuit Study on a power system is to calculate the available three phase symmetrical RMS fault current at each bus location to be used as part of a Protective Device Coordination Study.

III. SHORT CIRCUIT STUDY METHODOLOGY The Short Circuit Study was performed using a computer-based software program: Power Tools for Windows (PTW) by SKM System Analysis, DAPPER Comprehensive Fault Analysis Module. The systematic Short Circuit Study methodology begins by developing a system one-line drawing (within the software program) that defines the electrical characteristics of the power system. Each of the power system components (utility sources, induction motors, transformers, cables, protective devices, etc.) is modeled accordingly. When the study is run the software program places an assumed three phase fault at each bus location in the system and the available short circuit (fault) current is calculated for each bus location. The results of the computer generated study are described below (VI. SHORT CIRCUIT STUDY DATA).

IV. COORDINATION STUDY GENERAL INFORMATION The major reason for performing a Protective Device Coordination Study on a power system is to determine if the protective devices in that system provide a system of selective coordination. Coordination is defined as “properly localizing a fault condition to restrict outages to the equipment affected, accomplished by the choice of selective fault-protective devices”.

V. COORDINATION STUDY METHODOLOGY The Protective Device Coordination Study was performed using a computer-based software program: Power Tools for Windows (PTW) by SKM System Analysis, CAPTOR Protective Device Coordination Module. The systematic Protective Device Coordination Study methodology begins by utilizing the system one-line diagram (developed within PTW for the Short Circuit Study) that defines the electrical characteristics of the power system. Time vs. current coordination drawings that display the time-current curve(s) of one or more of the protective devices to be analyzed are then created. Each of the protective devices is individually modeled based on its specific time-current characteristics and the available three phase symmetrical RMS fault current. The results of the computer generated study are described below (VIII. COORDINATION STUDY DATA).

VI. SHORT CIRCUIT STUDY DATA The data generated by the Power Tools for Windows (PTW) DAPPER Comprehensive Fault Analysis software program consists of the following:

• One Line Drawing (Tab 2) • Input Data Report (Tab 2) • Fault Analysis Summary Report - Normal (Tab 3) • Fault Analysis Summary Report - Emergency (Tab 4)

The One Line Drawing shows each of the relevant power system components (utility sources, induction motors, transformers, cables, protective devices, etc.) and their interconnections. The Input Data Report summarizes the bus-to-bus interconnections and data used in performing the Short Circuit Study. The identification of buses was taken from the project documents. Each bus represents one of the following: a utility contribution point, a service end box, a switchboard a panelboard bus, or a motor connection point. The Fault Analysis Summary Report - Normal provides the three phase symmetrical RMS fault current for each major point (bus) in the power system under “normal” conditions (when the system is being fed by power from the utility). The Fault Analysis Summary Report - Emergency provides the three phase symmetrical RMS fault current for each major point (bus) in the power system under “emergency“ conditions (when the system is being fed by power from the emergency generator).

VII. PROTECTIVE DEVICE EVALUATION This evaluation consists of a comparison of the interrupting rating of each of the protective devices to the available short circuit (fault) current (at its location in the power system) under “normal” conditions and “emergency“ conditions. The results of this evaluation are presented in the Protective Device Evaluation Report (Tab 5).

VIII. COORDINATION STUDY DATA The data generated by the Power Tools for Windows (PTW) CAPTOR Protective Device Coordination Module consists of the following:

• Time Current Curves - Normal (Tab 6) • Time Current Curves - Emergency (Tab 7) • Component Setting Reports (Tab 8)

The Time Current Curves - Normal provide protective device coordination data for the power system under “normal” conditions (when the system is being fed by power from the utility) while the Time Current Curves - Emergency provide protective device coordination data for the power system under “emergency“ conditions (when the system is being fed by power from the emergency generator). The software is programmed to plot the curves such that the right-most point plotted for any of the individual device curves is at the calculated three phase symmetrical RMS fault current at the bus that feeds the device. Regarding fuse-to-fuse coordination, the most accurate and complete way to ensure coordination is to use the manufacturer’s (BUSSMANN) Selectivity Ratio Guide (line-side to load-side). For switchboard MSB, the ratio between the main fuse (FU-MSB-MAIN), a KRP-C-4000, and the largest feeder fuse (FU-EMDP), an FRN-R-600, exceeds the 4:1 minimum ratio required between these types of fuses. Therefore, since all of the feeder fuses are FRN-R type of fuses, it can be stated that there is selective coordination between the main fuse (FU-PP-R-MAIN) and all of the feeder fuses. For panel PP-R, the ratio between the main fuse (FU-PP-R-MAIN), an FRN-R-400, and the largest feeder fuse (FU-PP-K), an FRN-R-100, exceeds the 2:1 minimum ratio required between these types of fuses. Therefore, since all of the feeder fuses are BUSSMANN FRN-R type of fuses, it can be stated that there is selective coordination between the main fuse (FU-PP-R-MAIN) and all of the feeder fuses

IX. BASIC DATA AND ENGINEERING ASSUMPTIONS Basic data for the studies, including the system configuration and specific details for the system components were obtained from the following sources: • Con Edison (utility available short circuit contribution) • Project Plans • Equipment Submittals • Emergency Generator Supplier The following engineering assumptions were made: • In order to facilitate the modeling of the cable taps for the fire pump (CBL-

FPDISC) and for the fire alarm (CBL-FADISC) the impedance named “MAIN LUGS” had to be created (modeled as a 4000 amp bus, 0.1 feet in length).

• Where there are multiple branch protective devices of the same frame type fed from the same bus, we have only presented a time current curve for the largest branch protective device as this presents the “worst case” coordination situation.

• Induction motors are connected to the system and running.

Note 1: The interrupting rating of the circuit breaker is not adequate for the fault current (normal). A "series rating" (between the circuit breaker and the upstream fuse) that exceeds the fault current (normal) or a breaker with an interrupting rating that exceeds the fault current (normal) should be considered.
