Coefficient of Coupling: The amount of coupling between the inductively coupled coils is expressed in terms of the coefficient of coupling, which is defined as where M = mutual inductance…
Instantaneous Power Formula: Instantaneous Power Formula - In a purely resistive circuit, all the energy delivered by the source is dissipated in the form of heat by the resistance. In…
Static Protective Relay Articles: Static Relays Basics and Classification: A Static Relays Basics refers to a relay in which the measurement or comparison of electrical quantities is done in a…
Types of Arc Control Pots: There has been a continuous development in the types of arc control pots, the two basic forms of which are shown in Fig. (15.6). As…
Recovery Voltage: Recovery Voltage - While closing or opening the circuit breaker, the circuit constants play an important role. It was noticed in practice a circuit breaker that would operate…
Overcurrent Protection Relay in Power System: The technique of Overcurrent Protection Relay in Power System is still widely used as a means of detecting faults on distribution system and on…
Transistor Relays: These are the most widely accepted type of static relays, so much so that when we say static relays, we can safely infer transistor relays only. The transistor…
Transductor Relay (Magnetic Amplifier Relay): Transductor Relay - Since relays now have to perform much more complicated functions, many types tend to become very complex mechanically, and hence costly, to…
