hello! can anyone explain to me how a 3 speeds table fan
work? what are the factors that are controlling the speed of
a normal table fan? Is it by varying the voltage or changing
the magnetic field? would appreciate your reply :) thx in
there is a line fault some where on the ove head
distribution line. how will i locate the fault for clearing
it? ofcourse i have to megger the line but what information
makes me clear that the fault is in that section of the
if a damaged 500kva transformer with %impedance 2.6 is
replaced by two transformers of 250Kva with different %
impedance will they be able to catter the load. what will
be the ratio of load on the two transformers if the %
impedance is in the ratio 1:2
Explain how you can give the overload setting to any Motor

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
