Power Factor by Two Wattmeter Method: When we talk about the power factor in three-phase circuits, it applies only to balanced circuits, since the power factor in a balanced load…
Three Wattmeter and Two Wattmeter Method: In this method, the three wattmeter are connected in the three lines as shown in Fig. 9.45, i.e. the current coils of the three…
Reactive Power with Wattmeter: We have already seen earlier that the difference between higher reading wattmeter and lower reading wattmeter yields VLIL sin Φ. So, the total reactive power =…
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…
Frequency Domain Network Function: As the frequency domain network function is a complex function, it can be expressed mathematically in two ways i.e. using rectangular coordinates or using polar coordinates.…

Polyphase Circuits Articles: Polyphase System: In an ac system it is possible to connect two or more number of individual circuits to a common polyphase source. Though it is possible…
Leading Power Factor Load: Suppose the load in Fig. 9.46(a) is capacitive, the wattmeter connected in the leading phase would read less value. In that case, WR will be the…
