I.  Introduction

 

ETCR048H High Voltage Clamp Current Sensor is specially designed for high voltage current measurement, uses the latest CT technology with unique automatic plug function, composed of special detection clamp and high voltage insulation rod; the integration design of clamp and lead area ensures high-precision, high-reliability and high stability year-round uninterrupted testing.

ETCR048H High Voltage Clamp Current Sensor can be used in the measurement of high voltage line current, currents on both sides of transformer, variable ratio test, online current monitoring below 60KV, safe and time saving. If not use insulation rods, it can also be used as high-precision low-voltage clamp current and current leakage sensor to accurately measure 1mA current or current leakage. It is widely used in power plant, substation, industrial and mining enterprise, inspection station, electrician maintenance department for current sensing, power audit and field working. Insulation rod is light and convenient, with the characteristics of moisture resistance, high temperature resistance, anti-impact, anti-bending, high insulation and scalability.
