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…
Three Phase Balanced Circuit: The analysis of Three Phase Balanced Circuit is presented in this section. It is no way different from the analysis of AC systems in general. The…
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…
Potential Transformer Tests: The three Potential Transformer Tests are namely, Polarity check, Ratio check and Phasing check. Polarity check: Polarity check in Potential Transformer Tests is performed in the same…
Motor Protection: Motor Protection - There is a wide range of motors in existence for various purposes. However, the fundamental problems affecting the choice of protection are independent of the…
Restricted Earth Fault Protection: This type of Restricted Earth Fault Protection is provided to detect earth-faults within the protected zone of the transformer. A CT is fitted in each connection…
