why the generating voltage in India is 11kV or why is it be
transmitted as multiples of 11
Answer Posted / m.s.v.
We always use a multiple of 1.11 bcoz for a pure sine
wave the FORM FACTOR is the ratio of rms value of voltage
or current with the avg. value of voltage or current and for pure sine wave rms value of current is Imax/root '2' and avg. value is 2Imax/pie. and which comes out to be 1.11 so,we cant have a combination of other then a multiple of 1.11.

we have require a Motor (1500kW, 6.6kV, 50Hz) which shall operate at 1500rpm during 30min and after it shall run on 500rpm during 15min. The same cycle shall be repetitive during the whole working days. Which method is best and economic to achieve such type of task. VFD, VVFD, Pole changing motor etc.

we have earthmat at 110KV substation.we would like to take earth resistance.b some says that by connecting earth megger terminals (C1,P1) at middile point of earthmat (at riser) will cause voltage gradient at other earthmat nods and dont get exat earth resistance.when connecting at end nods will get exat value . is it correct .please explain
