Fault level
(OP)
Excuse my ignorance. Can some explain what is the meaning of fault level with reference to power transformers.
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: Fault level
RE: Fault level
Fault level at a bus or at a transformer or at any other part of the system refers to the same. It is the MVA / current that will appear at the terminal of the equipment wheneven falut occurs. May be you can define it for a Balanced fault ( 3 phase to ground) and un balanced fault ( sigle line to ground) By conducting studies prior to the commissioning you can be aware of the fault levels in the system and can think of designing Primary grounding resistance / reactance or secondary grounding resistance. The fault level of the system connected to grid through a low impedance transformer is high the same is true in the case of parallel connected transformers ( so people always not operate the gris transformes in parallel)
hope this will help and sorry if it is out of context..
