Model OVM - Over Voltage Relay
When supply and input sample voltages are connected to terminals A1, A2 and U, V respectively and in addition, voltage is in allowed range, device internal relay would be open(internal contact of terminal 15 to 18 is established) and PWR and FAULT signals would be on and off respectively. If input sample voltage is higher than the limit adjusted by VOLT potentiometer handle, device starts timing and at the end of time adjusted by DELAY potentiometer ...

Borna - Model CT - Core Balance for Earth Fault
This core balance CT acts based on vector summation of passing currents through the device. If vector summation of passing currents is zero, output voltage of core balance CT will be zero. But if it is not zero, there would be a voltage at core balance CT output proportional to leakage current. The voltage magnitude is proportional to leakage current (100 mV/A and linear up to 100 A). According to the device setting, connection or disconnection command ...
