|define B types and C types
in MCB ?
|how can we measure 220kv or more than these voltages ...?and
also how can we conform whether we r getting 220kv from
generating stations throuth the h v transmission lines?
|whether Transformer is singly excited or doubly excited machine?
|what modulation is used in landline telephone signals?
|Why tripping not occur when the transmission lines (11KV &
above) breaks? Doesn't
we provide earthfault protection for it?
|1)Why potential transformer primary site grounded?
2)can be loop between neutral & body for grounding?
3)What is the difference between ELCB &RCCB?
4)Why we use iron core in transformer insted of wooden core?
5)what is the principle of excitation?
6)Why we test the core balance test for transformer?
7)what is creepage?What is the creepage length for
insulators at different voltages?
8)How much type of relays used for differential protection
of generator,transformer & busbar protection?
|what is NGR in generator?
|improve power factor by : 1)shunt reactor 2)shunt
capacitor 3)series capacitor 4)series reactor
|What is the current carring capacity of 0000SWG and 0SWG
overhead solid bare copper conductor. If possible please
provide reference for various sizes Vs current ratings
|I WOULD LIKE NOW WHY WE CANT USE SOME CT FOR MESARING AND
|In an panel board if the outgoings are power plugs and
motor equipments...what should we choose as the incomer of
the of the panel board?? MCCB OR ISOLATOR?? Should we use
ELCB protection??if so where??
|after parallaing two generators current is shooting up in
both the generators.for ex: load is 400 kw..after paralling
and load sharing current in running gen is approx 900 amps
and incoming is 750 amps which is too high when trying
toshift the load current in incoming gen is coming more
than 1300 amps and both getting tripped and making
