This optional study is performed to determine the appropriate type of protective device, location and settings for adequate equipment protection. Sufficient operating times are maintained to allow for inrush currents experienced when energizing transformers or starting motors.
This study will reduce the amount of equipment affected by an overcurrent trip and the amount of incident energy a technician is subjected to when an arc flash occurs. The fault current will
open equipment nearest to the fault to avoid overall system blackout. You will receive time-current coordination curves that illustrate coordination among devices shown on one line diagrams.
Load Flow Study
This optional study calculates the voltage drop on each feeder and transformer branch, voltage on each bus and projected power flow and losses in the system. This study may be used for conventional voltage drop analysis, loss analysis, power factor studies, capacitor placement, long-line charging effects, impact loading for motor starting studies, generator sizing and for cogeneration analysis.
