Gases and Gas Mixtures for Insulation Purposes: Over the years, considerable amount of work has been done to adopt a specific gas for practical use. Before adopting a particular gas…
Medium Transmission Line Voltage: In short transmission line calculations; the effects attic line capacitance are neglected because such lines have smaller lengths and transmit power at relatively low voltages (<20…
Constants of a Transmission Line: A transmission line has resistance, inductance and capacitance uniformly distributed along the whole length of the line. Before we pass on to the methods of…
Power Factor Correction Circuit: To calculate Power Factor Correction Circuit, Consider an inductive load taking a lagging current I at a power factor cos Φ1. To develop Power Factor Improvement…
Power Factor Improvement: The low power factor is mainly due to the fact that most of the power loads are inductive and, therefore, take lagging currents. In order for Power…
Current Source Inverter Fed Induction Motor Drive: Current Source Inverter Fed Induction Motor Drive - In a voltage source inverter fed induction motor the applied voltage to the stator is…
Influence of Static Protective Relays: Influence of Static Protective Relays on the associated equipment like current transformers, voltage transformers, etc,. Let us discuss one by one. Current Transformers: Burdens on…
Static Relay: The term 'static relay' is generally referred to a relay incorporating solid state components like transistors, diodes, resistors, capacitors, etc. In this type of relay, the functions of…
