for longer period
in 400 kv system why should trip both side CB when we give hand trip?
what is the reactive power what is the use of it in system
how much up to LT Voltage range?
how LVDT works?
What is the difference between XLPE & FRLS cables? Is FRLS cables is a type of XLPE cable or both r different?
In Indian Household, generally we receive 220V AC single phase supply. But AC has 2 phases, +ve & -ve. So in +ve half cycle current is flowing...so what happens in the -ve half cycle?? Please illustrate.
what is high and low cut off voltage of BB and DG at SPS????????
why we use 110vac in overhead crains? why not 220v, 24v
along with technical test papers
