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?
I want to use Induction motor to open and close a 1 ton
door. How much power do I need.
how you taken aotitude test
WHY RATING OF VCB NOT LESS THAN 630A
at what rate the micro controller increment its timer....is
it 1micro seconds or 1/(12*10^6) seconds
If there is no problem with the electronic circuit and
regulator then why the motor start rotating at low value of
regulator with full speed both at laod and no load???
and if my judgement of circuit is wrong then what is your
1.what is difference between ATS & STS main use.
2.what is difference between ACB& VCB With symobles,and
main partes, manimum range.
3.How many types of relays and main function.
