Read MoreWhat is a Circuit Breaker? Working Principle, Types, Applications
Circuit Breaker. A circuit breaker is a type of switch that is designed to interrupt the flow of nominal, abnormal, or fault current. Whenever a high magnitude of current flows through the circuit, the circuit breaker works as a mechanical device that can easily cut off the power supply and protect the electrical system from damage.
Read MoreElectrical Circuit Breaker Working Principal Operation & Types
The potential energy can be stored in the circuit breaker by different ways like by deforming metal spring, by compressed air, or by hydraulic pressure. But whatever the source of potential energy, it must be released during operation.

Read MoreEnergy storage
Energy storage is the capture of energy produced at one time for use at a later time [1] to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential ...
Read MoreWhat is 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 breaker''s contacts are separated within an insulating oil. When a fault occurs in the system, the circuit breaker''s contacts are opened under the insulating oil, creating an arc between them.
