Due to generator winding insulation problem

Insulation

Answer / n.bharat mohan

generally a high voltage is transmitted to incure the losses, so as to reach the desired voltege at the end consumer.To obtain these high voltages we prefer transformers during the trasmission of power instead of generating a high voltage.
generally it is not preferred to generate because when we prefer a 11KV generation we require a huge amount of design and large cost is preferred instead of it we can prefer a method to obtain a high voltage is by using transformer.

DGs fuel and lube oil filters are not equal to one another.Why it is so.For example one MTU enginee fuel filter is one and lube oil filter-02nos other DGs are more.Please explain

I hv a question regarding power factor improvement just after transformer. I request you to reply me plzz. thank you sir. My friend has a small unit of fabrication. in his factory the main load is a welding machine, lathe machine, grinding machine. this load is not continuous type. now our electricity board has installed 16 KVA, 11000/433 V transformer for our factory. In the energy meter (trivector meter) at LV side of transformer, i hv seen power factor value of 0.15 only when only 3 KW load was flowing. Further electricity board has suggested to install 4 KVAR capacitor at LV side after energy meter. Now my question is that if we permanantly install and switch on 4 KVAR capacitor after energy meter, during some load on transformer and also without any load on transformer, wht will be the power factor shown in energy meter?i dont want to get any penalty by electricity board, so plz suggest me if i can permanantly install and switch on the 4 kvar capacitor or not at LV side of transformer just after energy meter? Thank you again and awaiting for ur positive reply soon.
