TRXL-60W
TR
Product Overview
Transformer is the key equipment of the power system, and its normal operation is vital to system safety. During operation, the alternating magnetic field generated by the windings through parasitic capacitive coupling, will make the core to the ground to produce suspended potential, resulting in the existence of potential difference between the internal components, which may lead to spark discharge, endangering the insulation. Therefore, the core must be single-point grounding to eliminate suspended potential.
If the core multi-point grounding, will form a closed loop loop current, resulting in local overheating, oil decomposition and insulation degradation, and in serious cases, burn the core, resulting in major accidents. Monitoring the core grounding current can be timely detection of such faults. The sensor used for this purpose is made of high permeability material, combined with deep negative feedback and multi-layer shielding technology, realizing fully automatic compensation of the iron core to zero magnetic flux state, accurately detecting 100μA-700mA industrial frequency current, and possessing excellent anti-temperature drift and anti-electromagnetic interference capabilities, ensuring accurate sampling in complex power station environments.
Product Features
