We in my plant one of the transformer showing neutral to earth voltage is 22V how to solve it
3 4031why in some cases the receiving end voltage is higher than the sending end voltage in transmission line (called 'Ferranti effect') ????? whts the reason behind tht???
3 6105Hi 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.
14811)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 11295Which is is best option for 33 kv line incomer.I am Desinging the panel for new projects and i would like to get Your opinion on this Vcb or sf6. Please help me with your replies. Thanks D p singh
