What is Phase Sensitive Detector or Phase Meter Circuit?: Figure 10.4 shows a Phase Sensitive Detector or Phase Meter Circuit for comparing an ac, signal with a reference signal. The…
Digital Phase Meter Block Diagram and Working Principle: Digital Phase Meter - The simplest technique to measure the phase difference between two signals employs two flip-flops. The signals to be…
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…
Three Phase Cycloconverter - Types, Working and Applications: A cycloconverter converts ac at one frequency to an ac of another frequency. Cycloconverters can be classified as single-phase to single-phase, three-phase…
Single Phase Half Wave Controlled Rectifier with Resistive Load and Inductive Load: In a Single Phase Half Wave Controlled Rectifier only one SCR is used in the circuit. It is…
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 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…
