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. MRD-NP 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.
