On-line Monitoring System for Grounding Current of MSDTX Transformer Core Clamp

Transformer is one of the key equipment in the power system, and its normal operation is an important guarantee for the safe, reliable, stable and economic operation of the power system. When the power transformer is running, there is an alternating magnetic field around the winding. Due to the effect of electromagnetic induction, there is a parasitic capacitance between the high-voltage winding and the low-voltage winding, between the low-voltage winding and the iron core, and between the iron core and the shell. The live winding will generate a floating potential between the iron core and the winding through the coupling effect of the parasitic capacitance. Due to the unequal distance between the iron core and other metal components and the winding, there is a potential difference, when the potential difference between the two points to be able to break down the insulation between them, it will produce intermittent spark discharge, the transformer oil and solid insulation have adverse effects, it is necessary to connect the iron core and the shell, so that it and the shell and other potential.
