1、Summary
ZEDZ Transformer/Generator Neutral Grounding Resistor Cabinet Through the grounding resistor can limit the fault current to the appropriate value,Make relay protection have enough sensitivity and selectivity,At the same time make the fault point as far as possible local minor damage,Limit the transient overvoltage to 2.6 times the normal line voltage to the neutral point voltage,Restrict arc burning again,Prevent damage of gap arc over-voltage main equipment,At the same time to prevent ferroresonance over-voltage also has a significant role.There are mainly generator neutral grounding resistance cabinet/Transformer neutral point grounding resistance ark/Low voltage neutral point grounding resistance Such kind,It can customize according to user's need.
