Power Measurement in Single Phase Circuit by Wattmeter: Wattmeters are generally used to measure power in the circuits. A wattmeter principally consists of two coils, one coil is called the…
Average Power Formula: To find the average value of any power function, we have to take a particular time interval from t1 to t2; by integrating the function from t1…
Overcurrent Protection Relay in Power System: The technique of Overcurrent Protection Relay in Power System is still widely used as a means of detecting faults on distribution system and on…
Instantaneous Overcurrent Relays: If the relay operates instantly without any intentional time delay, this characteristic can generally be satisfied by a relay of the non-polarized attracted armature type. This relay…
Full Wave Rectifier DC Power Supply: Like half-wave rectifiers, full-wave rectifiers require filter circuits to convert the output waveform to direct voltage. Figure 3-13 shows a Full Wave Rectifier DC…
Measurement of Power Articles: Bolometer: Bolometric measurements are based on the dissipation of RF power in a small temperature sensitive resistive element, called a Bolometer. This bolometer may be a…
Power Frequency Overvoltages in Power Systems: The Power Frequency Overvoltages occur in large power systems and they are of much concern in EHV systems, i.e. systems of 400 kV and…
