How are Ground faults and shorts cleared on the secondary side of a utility transformer?
When a ground fault developes on the secondary side of a utility transformer on the line side of the main circuit breaker what happens?
Will it blow itself clear?
How is a short circuit cleared in the same situation?
Does the utility transformer have secondary overcurrent protection?
If not, will this short circuit current pass through the transformer to the primary side?
If so,will it open the primary overcurrent device
protecting the transformer?
Is the secondary fault current large enough to accomplish this or will it just blow the secondary winding?
Thanks, I look forward to your comments.
