What's an AVR? What's its purpose in Generators?4 5633
Hi If connecting a temp generator 670KVA .415kv with step up Tx .415/11kv. I am given Generator impedances Z1 Z2 Z0 to 100MVA base. Do I need to work out the generator fault current by using these impedances i.e gen rating / impedance. Then use this as my source impedance for the calculations that follow.1481
How to run a three phase motor into single phase........1496
1)Why potential transformer primary site grounded? 2)can be loop between neutral & body for grounding? 3)What is the difference between ELCB &RCCB? 4)Why we use iron core in transformer insted of wooden core? 5)what is the principle of excitation? 6)Why we test the core balance test for transformer? 7)what is creepage?What is the creepage length for insulators at different voltages? 8)How much type of relays used for differential protection of generator,transformer & busbar protection?5 11295
