Introduction
An electrical power system is very complex. It needs some form of switchgear in order that it may be safely and efficiently controlled or regulated under both normal and abnormal operating conditions.
Circuit breaker is an automatically operated electrical switch.
It protects an electrical circuit from damage caused by overload and short circuit.
Its basic function is to detect a fault condition and, by interrupting continuity, to immediately discontinue electrical flow.
Unlike a fuse, which ope ....etc

ADJUSTABLE CIRCUIT BREAKER
INTRODUCTION
OBJECTIVE OF THE PROJECT:
In a circuit breaker there will be some reference value for which it has to be tripped. But in this ADJUSTABLE CIRCUIT BREAKER we can change the reference value in certain limit this limit depends on the interest of manufacturer.
That is in this project we are developing a circuit breaker in which the tripping current can be varied here in this project it is fixed between 0.1 A to 1 A.
Circuit Breakers:
A circuit ....etc

CIRCUIT BREAKERS
Abstract:
A circuit breaker is an automatically-operated electrical switch which is designed to protect an electrical circuit from damage caused by overload or short circuit.
Used to prevent the heavy current from damaging power system components.
Unlike fuses, normal operation can be resumed with minimal turn around time.
K ....etc

INTROUCTION



New maintenance techniques and methodologies are emerging, while the circuit breakers keep improving in their designs and functions . As an example, some new circuit breakers have embedded monitoring instruments available to measure the coil current profiles and the operation timing . The recorded information can be used to monitor the condition of breakers during each operation. In this case, it may be more appropriate to replace the time-directed maintenance by condition-directed maintenance practice . When applied properly ....etc

ESSENTIAL QUALITIES OF HV CIRCUIT BREAKER

High-voltage circuit breaker play an important role in transmission and distribution systems. They must clear faults and isolate faulted sections rapidly and reliably. In-short they must possess the following qualities.

In closed position they are good conductors.
In open position they are excellent insulators.
They can close a shorted circuit quickly and safely without unacceptable contact erosion.
They can interrupt a rated short-circuit current or lower current qui ....etc
