Our aim here is to calibrate the given Single-Phase Energy Meter using a precession Wattmeter and stopwatch using or employing phantom loading. The main apparatus required for conducting this practical experiment include: Single-Phase Induction type Energy Meter – 240V (5-10)A Wattmeter 300V/10A UPF Phase ...Read More

3-Voltmeter Method of Measuring Choke Coil Parameters:- The choke coil parameters we are going to measure in this 3-voltmeter method are – the inductance, resistance as all choke coils have inherent resistance in addition to their inductance. We also measure the quality factor and ...Read More

We aim to measure the resistance of a given resistor using Kelvin Double Bridge and determine its tolerance. Kelvin Double Bridge is nothing but a modification of Wheatstone bridge. It is used for measuring of low resistance to a good precision. It compares two ...Read More

Here we aim to measure the three phase reactive power ‘Q’ absorbed by the given 3Φ induction motor by using single wattmeter. The formula for the reactive power ‘Q’ absorbed by “Balanced Load” is given by where, Q = Total reactive power absorbed VL ...Read More
