High Accuracy AC Leakage Current Sensor

WBL411F27(High Accuracy AC Leakage Current Sensor) adopts the principle of electromagnetic isolation to measure the AC leakage current in the power grid in real time and transform it into the same-frequency in-phase tracking voltage (Ug) output. High Accuracy AC Leakage Current Sensor is suitable for single-phase or three-phase AC grounding grids, monitoring the phase-to-ground leakage current of the phase line; monitoring the grid differential current, ie zero-sequence current, in a single-phase or three-phase AC ungrounded grid.

Advantages:

   High precision, 

   High isolation, 

   Low power consumption, 

   Low drift, 

   Wide temperature range,

   Anti-interference, 

   Strong ability, 

   Wide working power range. 

Applications:

   Intelligent low-voltage power distribution system;

   DC power screen, box substation;

   Temperature and fire monitoring for transformer, fire monitoring for cable;

   High-voltage switchgear fiber optic temperature measurement system;

   Transformer contact monitoring.
