  • Power Substation Design Calculations - A Checklist of 18

    Substations are vast. A piece of wire connecting a battery to a motor load can span hundreds of feet. Because the copper or aluminum wire has resistance, some power is lost as heat resulting in a voltage drop along the wire. Due to this drop, the voltage at the receiving end may not be adequate to start the motor. Substation image credit: WAPA.
