Earth Fault Loop Impedance with Safety Generator
Former Community Member
Do I take this into consideration? If so how do I size wire in a building with a safety generator? What is my "Ze" when the supply switches from DNO to the safety generator? How do diesel generators behave during faults?
Right, but when the fault happens a few cycles latter the excitation would increase the voltage, and the engine will try to keep up torque, increasing the output current. If the machine can output a value mostly in the 7x range for 5 seconds the MCB can open without the use of RCDs and the like.
