why do you add the load short circuit impedance when
considering short circuit amperage. It seems that you should
only consider supply.
If you need to consider loads and you don't know what loads
are to be added , what would be a good sub-transient
reactance rating for the loads?
is KVAR (not reverse power) relay necessary to protect from
excitor field failure on a brushless, synchroneus generator?
Some people with previos experince tell me no but the
manufacturers tell me it is designed for that purpose.
Is it that it is only necessary for brushless generators
and not the older style with the slip rings and brushes?
WHAT ARE THE SITE TEST APPLIED ON A SURGE ARRESTORS? DO
MEGGER TEST APPLIED ON SURGE ARRESTOR? IF YES THEN WHAT ARE
THE ACCEPTED IR VALUE REQUIRED FOR SURGE ARRESTORS FOR
VOLTAGE LEVEL 11KV, 33KV, 66KV 132KV, 220KV AND 400KV?
what is the significance of cabability curve of alternator
IN MY SYSTEM THERE IS ONLY OVER CURRENT EARTH FAULT RELAY
IS AVAILABLE. FOR THE UNBALANCE SENSING IS THERE ANY RELAY
IS AVAILABLE? THE SAME CTs WHICH ARE USED FOR THE OVER
CURRENT EARTH FAULT RELAY CAN USE FOR UNBALANCE ALSO?
