check?
150kw , 440 is a large motr. the starting current of this
induction motor will be 5-8 times depend on drive ex-fan.
and coast for 6-8s to attain full speed.
so, the new contactor shall be good quality , with
overload,instantaneous with time delay shall be selected.
Reverse rotation protection, vibrations,

how i sync. the different size of generator.
how the earhing is done on ship and airplane.
whenever any squirrel or a crow falls on the transformer input line then there is a big explosion and 440 volts of power is being discharged through the neutral line due to which appliances in off mode are also burned.we have earthing for the transformer as well as the bus bar chamber.why is it happening?
LT, CC and LMU installed at both the outgoing circuits of 132 kv double ckt transmissio what its means ? and what are there use ?
Does voltage and current can be seperated?
What are the relays in ACB and VCB
why the transformers are rated in kv not kw?
What is ST and specify its range of voltage.

Hello seniors m an engineering student in 3rd yr..i want to know what are the software course in electrical field?i wanted to do certification course but i dont know much about the course?..Regards
what will happen if earth of 33 kv cable (earthed system) is not connected to earthing pit?
If the generator will trip, what you will do as an electrical technician in charge.
