Types of Protection

Types of Protection: When a fault occurs on any part of electric power system, it must be cleared quickly in order to avoid damage and/or interference with the rest of…

Protective Relay

Protective Relay: A Protective Relay is a device that detects the fault and initiates the operation of the circuit breaker to isolate the defective element from the rest of the…

Circuit Breakers Definition: A circuit breaker can make or break a circuit either manually or automatically under all conditions viz., no-load, full-load and short-circuit conditions. This characteristic of the Circuit…

Sequence Networks Unsymmetrical Faults

Sequence Networks Unsymmetrical Faults: The analysis of an unsymmetrical fault by symmetrical components method can be conveniently done by drawing sequence networks. A Sequence Networks Unsymmetrical Faults of a particular…

Short Circuit kVA

Short Circuit kVA: Although the potential at the point of fault is zero, it is a normal practice to express the short-circuit current in terms of Short Circuit kVA based…

Symmetrical Faults on 3 Phase System

Symmetrical Faults on 3 Phase System: Most of the Symmetrical Faults on 3 Phase System on the power system lead to a short-circuit condition. When such a condition occurs, a…

Switchgear Definition

Switchgear Definition: Switchgear Definition status that, The apparatus used for switching, controlling and protecting the electrical circuits and equipment is known as switchgear. The switchgear equipment is essentially concerned with…

Three Phase Unbalanced Load

Three Phase Unbalanced Load: The 3-phase loads that have the same impedance and power factor in each phase are called balanced loads. The problems on balanced loads can be solved…
