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 : 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) ...
Latest Answer : Actually, we use fans for cooling of transformer fins. ...
What is the voltage drop for 100kw motor if the length of the cable is 200m and what is the cable size.
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. ...
How much voltage is present in neutral resistance?and how much voltage is present in earth resistance
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. ...
How do we select a cable for a machine as per standards. Is there is any standard to select a cable as per voltage, or as per KVA and as per amps ratings?
Latest Answer : When there is a sudden loss of load, The Generator terminal voltage increases due to the fact that the IX drop in the generator winding decreases. The EMF generated being the same the reduced reactance loss leads to a sudden rise in generator voltage..but ...
Latest Answer : When AC supply is given to the primary of the transformer current flows through the primary windings, inducing an EMF in the winding & creating a magnitic flux around the winding (i.e production of flux around the windings)Here since supply is AC-alternating ...
