Earth fault relay
Earth fault relay
(OP)
Hi Guys,
I need a help in looking for a procedure on how to set an earth fault relay
What are parameters needed, (eg. short circuit fault, etc..)
Thanks.
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: Earth fault relay
- earth fault current value
- grounding system (low R, high R, Peterson coil)
- CT connection (core CT or serial connection of the phase CTS)
- CT data (ratio)
- system configuration (voltage level, how many parallel branches, branches lengths)
You could need an earth directional relay
