Sensors for measurements on high voltage and current potential
The LiteWire sensors are suitable for MTE’s meter test equipment PRS 400.3 and PTT 2.1. The LiteWire is a true RMS meter designed for use by electric utilities to sense currents or volt- age waveforms from the primary side of their distribution networks.
A fiber optic link transmits information as well as establishes isolation between the high voltage potential at the sensor enclosure. The sensors are mounted on a hot stick and slipped over a high voltage line.
A fibre-optical cable connects the sensors to a receiver unit at ground potential.
This receiver contains the digital readout and an analogue output.
