INTRODUCTION

MEWOI125LE Split Type DC Leakage Current Sensor is used for measurement of high accuracy DC leakage current, low DC current. Adopt the latest CT technology, double shielding layer and split type design, portable, install on line, no need to disconnect the measured circuits, non-contact, safe and fast. It can be connected with phase detection analyzer, industrial control equipment, data recorder, oscilloscope, harmonic analyzer, electric power quality analyzer, high precision digital multi-meter, etc. Widely applied in electricity, communication, meteorology, railway, oilfield, construction, measurement, scientific and research teaching unit, industrial and mining enterprises.
