Since the transformer is not a power transformer, but an isolation transformer, no detail study is required. OF ELECTRICAL POWER CONSUMPTION As said earlier, the source of electrical power is through captive power generation by using The Gas-Generator generates power at 415 volt, 3 Ph, 50 Hz level. There are Generators : 250 KVA x 2 nos + 125 KVA x 1 no The details of Gas-Generators are : 250 KVA ( 2 nos) 125 KVA New Generator 125 KVA (2 nos) Old Generators Gas Engine : Model Engine : Model CJ125G5P, Sr. 125 KVA, NGEF sets, currently – – CJ250G5P, Sr. No. No. 25321873, 157 BHP, 1500 disconnected. 313 BHP, 1500 RPM, RPM, 24 volt battery, Make- Battery volt- 24 V, make- Jackson, Year- 2007 Jackson, 2010 Alternator : A.C., 3 Ph, 50 Hz, Alternator : A.C., 3 Ph, 50 Hz, 250 KVA, 1500 RPM, 348 RPM, 125 KVA, 1500 RPM, 174 Amp, 415 volt, 48 volt excitation, 58 volt excitation, make- type-HC143401, Sr. No. N10B01905, make- Stamford Stamford NOTE : 125 KVA new Generator generally runs during day time, often relieved to be taken over by 250 KVA generator. During evening time, either of the 250 KVA runs continuously. There is no operational log-book maintained by the Generator Operators. So, the electrical and mechanical parameters could not be checked. The is shown : single line diagram for the power distribution
