1.About us:
Baoding Tianwei Hengtong Electric co***ny is a domestic professional manufacture of power system neutral grounding equipments and complete implements ISO9001 quality management system. We have a excellent sales performance all over the world and have been exported to more than 40 countries. TWHT offers a complete range of products for the necessary neutral-point connections
2.General introduction
THT-ZT neutral grounding resistor cabinet (NGR or NER) are employed in medium-voltage AC distribution networks to limit the current that would flow through the neutral point of a transformer in the event of an earth fault. It connected between the neutral point of the transformer and the earth.
3.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.
