When an electric current coil of a wattmeter is connected to the electric current path R and the voltage coil is connected between the electric current R path and the neutral side of the balanced three phase supply, it shows 10 kW. The line voltage along the phase sequence RYB is 400 V. The current drawn by the current path is 54 A. What is the new reading of the wattmeter if the voltage coil is connected between the lines B and the Y paths, even if the electric current coil is continuously present in the line R?
What are the steps required in sequence to solve a circuit using superposition theorem? (a) Select any one source and short circuit all other voltage sources. (b) Find out the current or voltage across the required element, due to the source under consideration. (c) Open all current sources, if the internal impedance is not known. If known replace them by their impedances. (d) Add all the individual effects produced by individual sources to obtain the total current in or across the voltage element. Code :
