220KV Transformer Neutral Gap Grounding Protection Complete Set

Product Description and Application:

110kV, 220kV, 330kV is the main voltage level of the power supply system, the neutral point of the general use of direct grounding, due to relay protection settings and to prevent communication interference and other requirements, and in order to limit the single-phase short-circuit current, some of which use Neutral ungrounded way. In this mode of operation, due to lightning, single-phase ground short-circuit fault will cause a neutral point over-voltage, and transformers are mostly graded insulation, so over-voltage insulation of the neutral point caused a great threat, to be set to protect Device to prevent accidents.

Product Features:

1. Meet the standards, professional manufacturing;

2. The design of new, the overall installation, with a small size, easy installation and commissioning, high reliability characteristics;

3. Effective protection, stable characteristics, improve the protection of security and protection;

4. Group with flexible, easy to use;

5. Strong technical force, courteous service.
