Ⅰ.Introduction

ETCR085K Clamp Type High Accuracy Leakage Current / Current Sensor is widely used in the field of electric power, communication, meteorology, railway, oil field, military, measuring, teaching research unit, industrial mining enterprises, etc, for measurement of AC leakage current, current, frequency, phase sequence, power and electrical energy. It can be connected with high accuracy digital multimeter, data recorder, electric power quality analyzer, oscilloscope, industrial control instrument, etc. It adopts open jaws design, with opening size of 85mm×20mm, very suitable for the place of flat steel ground connection. No need to take apart measured wires, which make the field testing and maintenance more secure and convenient. The combination of two sensors can be used as the sensor of non-contact ground resistance online testing.
ETCR085K Clamp Type High Accuracy Leakage Current / Current Sensor adopts the latest CT technology, multilayer shielding techniques, least affection from external magnetic field, and capable of waterproof, rainproof, drip tight to make sure the high precision, high stability and high reliability of perennial uninterrupted measurement. Meanwhile, customizing is acceptable to meet more use of different places.
