Product Description

These sensors are supplied with the MCU520MV and measure the current output of 400:5 ratio CT’s fitted to MV cables. The sensors generate 100mV for 5A, which corresponds to 100mV for 400A MV current, i.e. 250µV/A, which is the same output as the standard GH600 Rogowski sensors. An internal voltage setting resistor sets the full scale output voltage to 100mV – this resistor also serves as open circuit shock protection for the installer.
