Difference between Static Relays and Electromagnetic Relays: The conventional electromagnetic relays are robust and quite reliable, but are required to operate under different forces under fault conditions. This leads to…
Powder Coating Process: Powder coating process is one of the most durable finishes that can be applied to industrial manufactured products, and offers excellent corrosion protection and is very safe.…
Negative Phase Sequence Relay: A negative phase sequence relay (or phase unbalance) is essentially provided for the protection of generators and motors against unbalanced loading that may arise due to…
Voltage Balance Differential Relay: In this voltage balance differential relay arrangement, two similar current transformers are connected at either end of the system element under protection (such as a feeder)…
Mho Type Distance Relay - Working and Characteristics: Mho relay is a high speed relay and is also known as admittance relay. It is also sometimes called an angle impedance…
HVDC Circuit Breakers - Construction and Working Principle: Light duty dc circuit breakers have been in use since long. However, there is lack of suitable circuit breakers for HVDC systems.…
Factors to be Considered in Selection of Fuse: In order to ensure that the fuses will correctly and reliably protect any given section or element of an electrical circuit, selection…
Different Types of Faults in Power System: A fault in an electrical equipment/apparatus is defined as a defect in the electrical circuit due to which current is diverted from the…
