usually fan having two types of windings,i.e starting wdg &
whenever we switch on the supply the fan may take the
moment slowly due to starting wdg,at this time fan requires
some reactive power(because fan wdg acts as inductive
load),at this time capacitor supplies this reactive
power.then only the fan will rotates with its own RPM.
Ac supply given to a equipment having winding then there is a lagging power factor then we use a capacitor which has leading power factor then voltage and current are in phase into some extent which increase power factor.
Can earth resistance be measured without connecting the
and should earthing connections be disconnected
What is the effect of connecting two cables of different
sizes in parallel with supply?
Thanks in Advance.
I am intrested to get in touch with some
tecnocrats/engineers,my mail i.d is :
To test Transformer we give HT side 440V to see wheather
that it is producing 17.6V on LT to verify Voltage ratio is
correct or not but when we give the 440V voltage to LT side
then what will happen to HT voltage ?
