Product Description

Transformer neutral gap protector device

Introduction:
110KV and 220KV is the main voltage grades in power supply grid, due to high voltage the neutral point usually
grounds solidly or neutral point of some transformers does not ground based on requirements of relay setting
and avoiding communication interference for limiting single-phase short-circuit current. By this way, the neutral
point would be overvoltage caused by lightning stroke or single-phase grounding faults. Moreover most
transformers are graded insulation, so the the overvoltage hazards to neutral insulation is huge. We must set a
protective device preventing such accidents from occuring. Transformer neutral gap protector of our company
is such a device for it. It is produced strictly as per DL/T620-1997 overvoltage protection and insulation co-
ordination of AC electrical equipments, applicable to 110 kv and 220kv power system where transformer neutral
point does not ground.
