ETCR007AD AC/DC Clamp Leakage Current Sensor
Ⅰ. Introduction

ETCR 007AD AC/DC Clamp Leakage Current Sensor is designed for measuring AC/DC current and leakage current under 600V line voltage, by adopting the latest CT technology and digital integrate technology. The small clamp is suitable for line densely places (electric power measurement system, the high speed rail system, car circuit overhaul, and so on), non-contact measurement, to ensure safe operation. It is small, with high precision, stable performance, can be connected with phase detection analyzer, industrial control equipment, data recorder, oscilloscope, electric power quality analyzer, high precision multi-meter. The sensor is widely applied in those fields as electricity, communications, meteorology, railroad, car industry, oilfield, construction, measurement, scientific & research teaching institutes, industrial and mining establishments.
