how to carry out Magnetizing Current Test on Distribution
transformer and what purpose we are doing this test.
why transformer rating in always in KVA ?
what ispositive, negative, zero sequence impedence?
How ElCB tripping if Neutral touch with ground
Why AC & DC capacitor are use in UPS ?
why motor rating in KW?
how to syncronize two dg sets
Why phase sequence must be same in any ht motor or generator
circuit?if phase sequence doesn't same whatever will be
affect on circuit?
hi, in the event earth grounding is not available in a
project, is there any other way to make the elcb work? fyi,
i have an instant water heater (6.5kw) installed, however
if there is grounding in the heating element inside the
heater assembly, i will get grounded.
thank you in advance to those who will answer my question.
A 1F capacitor is charged to 100V initially. A 1H inductor
is connected accros the capacitor througha a switch. The
current in the circiut when the switch is closed is____
pls,send the previous year written test questions.
In all analog voltmeters or ammeter showing some small size
symbols. as well as a star and in star 2no. digit, resister
symbol,and other. what is that's meaning ?
I am getting above 60 V as open delta voltage against single
phase unit ICT at tertiary delta formed and ICT getting
trippped on NDR. ICT tested and found in order. PTs provided
on tertiary are tested and in order. what may be the reason?
