• Magnetic and Controls design Grounding transformer for providing an artificial neutral point for ungrounded three phase power sytem
  • During the line to ground fault our grounding transformer provide an easy path to ground to limit the fault current and transient over voltage
  • Grounding transformers generally have short time ratings since the grounding transformer carry short circuit fault current till the breaker trips
  • The KVA rating of the transformer depends on the normal line to neutral voltage and fault current value for a specified time ,such as seconds to minutes
  • Generally grounding transformers are done in four configurations
