HVDC Circuit Breaker- Types, Working & Applications
The HVDC circuit breaker serves as a switch to interrupt the flow of abnormal direct current in a circuit. In case of a fault in
Power System
Testing of Circuit Breaker
Circuit breaker testing is more challenging compared to other electrical equipment, such as transformers or machines, due to the high short circuit current. Circuit breaker
Bulk Oil Circuit Breaker
Definition: A circuit breaker that uses a large amount of oil for arc extinction and insulation purposes is known as a Bulk Oil Circuit Breaker.
Types of Circuit Breaker
There are multiple ways of classification of circuit breakers. Circuit breakers can be classified into different types based on the medium used for arc extinction. Different media,
Air Break Circuit Breaker
The air break circuit breaker (commonly referred to as an Air Circuit Breaker or ACB) is designed to initiate and extinguish arcs in relatively still
Sulphur Hexafluoride(SF6) Circuit Breaker
A circuit breaker that uses pressurized SF6 gas to extinguish the arc is known as an SF6 circuit breaker. SF6 (Sulphur Hexaflauride) gas has outstanding
Zero Sequence Current
Definition: An unbalanced current flows during an earth fault in an electrical circuit. This current is known as the zero sequence current or the DC component
Oil Circuit Breaker
An oil circuit breaker is a type of circuit breaker that uses oil as a dielectric or insulating medium to extinguish the electrical arc. The
Pin Type Insulator (Pin Insulator): Construction, Uses, Diagram & Advantages
The pin type insulator is used for power distribution for voltages up to 33kV. It is mounted on the cross arm of a supporting tower.
Transposition of Conductors
Definition: The transposition process involves physically rotating the conductors so that each conductor takes up the next position in a regular sequence. This equalizes the
