In scott connection why connect teaser transformer to 86.6% and main transformer to 50%..
Explain the operation of variable frequency transformer?
Why efficiency in thermal power plant is low?
why to use freewheeling diode ( diode in revers bias mode) across dc coil
what is the AC Plant and how can do the work with parts and picture tell us 150 Tr
what is leading power?
in the Distribution system .which one is Most Economically used by Power Engineer ? a)3 Phase3 wire System or b) 3Phase -4wire System
Earth Is a very good conductor or very good insulator.? If a good conductor then why current donot flow through small piece f earth and if a good insulator then why we use it as return path in lines.???
the current which flows during lightening is ac or dc,,,,,,,,,,, WHY
can we use inductor in case of d.c.,if yes then what will happen in circuit
why do we connect droop ct{in gensets}in y_phase only
