Using the experience installing over 1000 LV monitoring systems using a variety of sensors types, the GridKey team specified a sensor specifically for retrofit installations.


When required to fit around larger conductors, multiple conductors or around fuse handles, a longer sensor can be supplied.

GridHound GH600 Sensor

The GridHound sensors were designed by the GridKey team specifically for retrofit to existing LV cabinets and they remain our most accurate sensors.

CT Sensors

These sensors are supplied with the MCU520MV and measure the current output of 400:5 ratio CT’s fitted to MV cables.
