5.Options include:
a.Earthing transformer or grounding transformer
When the transformer windings adopt delta connection and a Zigzag connecting, Grounding transformer needs to be separately installed, the THT-ZT-type neutral grounding resistor cabinet can be matched.
b.Intelligent control units.
It would not only monitor the earth fault and temperature of unbalanced current and resistors, but also record the current value, time, NGR temperature changes and grounding frequency. At the same time, it will transmit the above information to the main control room.
