when a airgap of the induction motor gets larger does it draw more current ??? does it power factor gets lower?
Why we cant store an ac power. If we coo store in which device we can?
difference b/w eath and neutral
why capacitor takes more current
while we select CT, why the CT ratio is divided by 5?? ex:250/5,15VA,CLASS-1 CT.Why it is divided by 5??Help me please
Why the ratation of fan is anticlockwise all over the world?
my self i am raghu working as tech.. in my college the maximum demand is 211 kva presently we are using 12kva capacitors the target power factor is .95 so what capacity of capacitor banks should i install
What is the differences in phase to phase voltages between star and delta connections of stator?
Dear Friends, I have a 500KVA transformer supplying whole factory having 3 phase and single phase mixed loads. Power room has ammeters connected via CTs for individual phase. Now I know that readings shown on meter for each phase say R,Y and B are line currents. But when I want to know the total on transformer do I need to add the currents of all three phases readings shown on meter or value for anyone phase will give me the correct power load on transformer for that point of time. 2. If ammeter shows unbalanced readings for R,Y, B phases say 150, 250 and 300 respectively so can I assume that 150A i.e average of 3 will be the 3phase load currents and remaining will be 1phase currents. Please clarify my doubt.
what is the term of desruptive voltage

Why syn. Generators are used for the production of electricity?
A genarator is connected through a 20MVA ,13.8/138 KV stepdown transformer to a transmission line. at the reciving end of the line a load is supplied through a step down transformer of 10MVA,138/69 KV rating .A 0.72 PU load evaluated on load side transformer ratings as base values ,is supplied from the above system for system base values of 10 MVA and 69 KV in load circuit the value of the load in generator circuit will be ...........
