Phase fault

[successwale]

I'm running 3.5MW deutz gas engine of which the outgoing breaker 2MVA always trips on PHASE FAULT and EARTH FAULT. I don't know what i can do ensure this did not repeat it self. please could be the sepam setting causing this?

Could be or could be an actual fault or Failing cable/ equipment. There is not enough info provided.

When does it happen? How often does it happen.
What do you do to come back online. What have you checked so far? Anyone else familiar with the system has any opinions?
Settings? System voltage?

How long has this been going on for?

Repeated trips of an engine will damage it, difficult to quantify the relationship between number of trips and damage.
