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…
Power in Three Phase Circuits: Measurement of power by a wattmeter in a single phase circuit can be extended to measure Power in Three Phase Circuits. From earlier Section, it…
Unbalanced Three Phase Circuit Analysis: Types of Unbalanced Loads - An unbalance exists in a circuit when the impedances in one or more phases differ from the impedances of the…
Bridged T Network Analysis: Consider Bridged T Network Analysis as shown in the Fig. 6.15 (a). We can consider bridged T network as a parallel connection of the two networks…
Network Topology: Basically network analysis is nothing but finding unknown branch currents or voltages across various branches. We can find these unknown parameters by using different network simplification techniques. These…
Circuit Breaker Analyzer: Short Circuit Generator: This is of a special design having very low reactance in order to give the maximum short-circuit output of the Circuit Breaker Analyzer. The…
Static Distance Protection Relay: Static Distance Protection Relay are characterized by having two input quantities respectively proportional to the voltage and current at a particular point in the power system,…
Logic Circuit in Static Relay: The concept of Logic Circuit in Static Relay can be better understood by considering the logic operations performed by the devices rather than the actual…
