XL Series Active Zero Flux Leakage Current Sensor

TRXL series active zero flux leakage current sensor is a kind of micro-current sensor specially developed for on-line monitoring of the insulation of high-voltage electrical equipment. It selects the material with high starting permeability as the iron core, adopts the unique depth negative feedback technology and multi-layer metal shielding measures, which can compensate the iron core fully automatically and make the iron core work in the ideal zero magnetic flux state. The sensor is capable of accurately detecting industrial frequency currents from 100μA to 700mA. The phase conversion error is no more than 0.01°, with good temperature characteristics and electromagnetic field interference ability, fully meet the complex power plant site interference under the equipment sampling accuracy.
