Sir,In our company there are 3 caterpillar make(capacity:(1)
3.3KV,2.5MW(2)3.3KV,2.5MW & (3)3.3KV,1.9MW) & 1 deutz make
(capacity:11KV,3.8MW)gas engines utilised,all are running
in paralell.
There are three transformer utilised,(1)
6.25MVA,3.3KV/22KV,Impedence voltage:6.7% used for two
generator,both are 2.5MW(2)5.5MVA,3.3KV/22KV,Impedence
voltage:7.2% used for one generator of 2.5MW & (3)
5.5MVA,11KV/22KV,Impedence voltage:7.8% used for one
generator of 2.5MW.all generator breakers capacity of
1250Amps.
Sir,I want the details of fault level calculation of
generator,transformer individually & for whole system.
If you require any information from me.feel free for
contact me sir.pl.send the answer of my question as the
earliest as possible.
Why efficiency of generator is higher than motor at a
particular load?

why is using sensor?what is differece between photoelectric
and proxmitty?

2- What are the percentages between excitation currents in
phase (R, S and T) in ∆ and Ỵ connections in excitation
Current test in transformers?
30
what is the transmission loss for electrical supply?
specifically a large shopping complex where the grid is
half KM away, what will the % of transmission loss? is
there any transmission loss for captive unit generation for
above set?
thanks

The metal-enclosed switchgear and controlgear is subdivided
into three
types:
1. metal-clad switchgear and controlgear; 2.
compartmented switchgear and controlgear 3. cubicle
switchgear and controlgear.
What is the main differnence between them. State some
example.
