Hi,

I have a strange situation here. One of my equipment is using 3phase 5 wire 400v input and it feeds many internal components with 230V single phase supply. once there was a problem in the neutral connection and the output at that time was >300 Volts instead of 230V. Can someone explain me why it happened like this.

Thanks in advance

Pramod
