can I improve the furnace power factor (10 mva transformer) by adding a capacitor bank before the transformer.Does system power factor vary a lot with the furnace PF?
when we design electrical schemes of 11/.415kv distribution..wen and were should we show the relays??what is the function of it?for example..we place EFR Relay CT between transformer neutral link and transformer earth.Like this what are the other type of relays we should use?why?where?Explain please..Thank you
what is self capacitance of inductor
We have studied about many techniques for finding the stability of system, ROOT LOCUS, ROUTH, BODE PLOT, POLER PLOT etc. In these which is used where. what are the difference among them... PLZ tell me.......
