Earth has the constant potential so we take it as reference.but in steo & touch voltage we use to calculate voltage of ground in 30 inch. How it is possible if no current can flow through ground?
Latest Answer : It is 1Suppose v= line voltage applied i=line currentFor star connected resistances power= ...
Latest Answer : The instantaneous voltage at time instant 't' in a three phase balanced circuit assuming that the voltage is applied at reference time ZERO and phase sequence to be +ve ( anti clockwise rotation of vectors) , is Em SIN(wt) for R phase, Em SIN(wt+120) ...
What are the technical reasons for soaking transformers for various times before allowing them to pick load after a fault or maintenance outage or as a new installation.
Latest Answer : Because, the load's are in parallel, if you switch on load due to parallel, total effective resistance decreses. Thus I=(V/R) according to OHM's law relationship the current drawn from the source increases. ...
In a synchronous motor armature current flows due to revolving flux which in turn rotates the load,but in no load condition armature current is zero hence thr is no revolving flux then how motor rotates? pls give books referance.
For an 100kw generator, only 50kw of load is connected. will the generator generate only 50kw or 100kw. if it generate 100kw what happens to rest of the 50kw. what happens if we connect more than 100kw of load?
Latest Answer : Purpose of collecting Knee voltage is to use the circuit as an operating or as an metering circuit.Operating circuit works far below knee voltage.Metering circuit works at the verge of saturation. ...
Latest Answer : The series capacitor is conected to compensate for the line inductance and thus decrease the line reactance so that more power can be tranferred through the line (EV/X sin(delta)) and thus the system stability can be increased. ...
1. what is the different between CGS system and MKS system? 2. When we connect the capacitor Banks in Series with the circuit 3. What is the difference between Earthing & grounding 4. how much voltage
Latest Answer : When the current lead in the circuit use the capacitor in series. ...
