ELECTRICAL CIRCUIT BREAKE R CIRCUIT BREAKER IS A MECHANICAL DEVICE DESIGNED TO CLOSE OR OPEN CONTACTS MEMBER,CLOSING OR OPENING OF AN ELECTRICAL CIRCUIT UNDER NORMAL OR ABNORMAL CONDITIONS.THIS TYPE OF DEVICE OPERATED   ON-LOAD AS WELL AS   OFF-LOAD OF AN ELECTRICAL NETWORK.IT DIFFERS FROM ELECTRICAL ISOLATOR BECAUSE ELECTRICAL ISOLATOR IS ONLY OPERATED OFF LOAD. CIRCUIT BREAKERS ARE INSERTED IN ELECTRICAL SYSTEM FOR PROTECTION OF ELECTRICAL CIRCUITS FOR OVER CURRENT OR SHORT CIRCUITS.CIRCUITS BREAKER EQUIPMENTS CONSISTS  TRIPPING  COIL .THIS COIL DISCONNECT THE CONTACTS MEMBERS DURING FAULTY CONDITIONS AS WELL AS MAINTENANCE OF THE BREAKER. CIRCUIT BREAKER FOLLOWS SOME FOLLOWING RULES 1 .CURCUIT BREAKER CARRIES FULL LOAD CURRENT OF THE EQUIPMENT  OR LINE. 2 .IT IS A ON-LOAD SWITCH AS WELL AS OPERATE OFF-LOAD SWITCH. 3. IT BREAKS THE LINE ONLY OVER CURRENT OR SHORT CIRCUIT CONDITION POWER CIRCUIT BREAKER IS RATED IN MVA  WHICH IS MULTIPLICA...

                     Current transformer CURRENT TRANSFORMER IS USED IN MEETERING,PROTECTION PURPOSE.IT STEP DOWN THE VALUE OF CURRENT WITH RESPECT HIGH CURRENT FLOWING THROUGH LINE.WHEN A FAULT OCCURE IN THE LINE CURRENT TRANSFORMER COMPAIR THE VALUE OF ITS SECONDARY CURRENT SETTING VALUE THAT IS 1 OR 5 AMP,THEN EXTRA HIGH VALUE CURRENT FLOWING TO THE RELAY AND RELAY CONTACT CLOSED THEREFORE TRIP THE LINE.
