Web5.10 Insulation levels Transformers shall be designed to provide coordinated low-frequency and impulse insulation levels on line terminals and low-frequency insulation levels on neutral terminals. The primary identity of a set of coordinated levels shall be its Maximum System Voltage and Basic Lightning Impulse Insulation Level (BIL). WebMar 4, 2024 · Most medium voltage NGR I have seen are sized for 50A. When a fault occurs, the faulted phase goes to zero Volts to ground - yep it is shorted. This raises the neutral voltage to 11,000/ (sqrt (3)) = 6350 Volts above ground.. So sizing the NGR to limit the fault current to 50A would give NGR = 6350/50= 127 ohms.
