You can simply calculate HT FLA like- MVA/Sq root of 3x HV
or my simple technic KVA/19.20, 630/19.20= 32.81A is HT side Full load current and you can use 2 times higher ratings cable....

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.
During Testing of Maintenance Free Earthing, How deep should be the Spikes of Earth Test Meter should be inserted in the soil(one spike is 15 Meter & Other spike is 30 Mtrs away from the Main Earth Electrode. Because, recently, we observed that when spike is inserted 3-4 Inch in the earth- results are better, If spike is inserted 1 feet deep than results are increasing.
