0IL 2IR21I! REA4ERIT IS WELL KNOWN THAT WHEN A CIRCUIT CARRYING A LARGECURRENT IS BROKEN, AN ARC OCCURS AT THAT POINT WHERE THECONTACTS ARE SEPARATE, THE ARCHING IS SPECIALLY SEVERE

WHEN HIGH VOLTAGES ARE INVOLVED AND IF A SHORT CIRCUITOCCURS ON A HIGH VOLTAGE CABLE WHICH IS SUPPLIED FROMLARGE POWER STATION. THE ARC WOULD BE POWERFULL TO BRIDGETHE CONTACTS OF THE SWITCH AND DESTROY IT BY BURNING. THEDEVICE IS EMPLOYED AS AN OIL BREAKER. AN OIL BREAKER POSSESTHE PROPERTY OF ALWAYS BREAKING AN ALTERNATIVE CURRENT ATITS ERO VALUE.

THESE SWITCHES ARE SUITABLE FOR A MA'IMUM VOLTAGE OF ?.? KV.THE CONTACTS OF THESE SWITCHES , WHICH BREAKS HIGH TENSION

CIRCUIT, ARE IMMERSED IN OIL TO ENSURE RAPID & EFFECTIVERAPTURE OF THE CIRCUIT. WHEN THE ARC OCCURS, THE OIL IN ITSPATH IS VAPORISED AND THE GAS THEREBY GENERATED E'TRACT APRESSURE ON THE SURRROUNDING OIL. THIS PRESSURE IS UTILISEDIN ARC CONTROLLED DEVICES TO CAUSE A MOVEMENT OF FRESHCOOL OIL ACROSS THE PATH OF THE ARC, THEREBY EFFICIENTLY

ASSISTING ITS INTERRUPTION.

/. TO PERMIT THE TRANSMISSION LINES TO BE CONVENIENT PUT INTO AND TAKEN OUT FROM SERVICE.//. TO DISABLE THE SOME PLANT AND LINES WHEN THESE BECOME

FAULTY, TO BE REPIDLY AND SAFELY ISOLATED BY AUTOMATIC MEANS. THE FIRST OF THESE CAN BE SERVED BY RELATIVELY SIMPLESWITCHES THE SECOND HOWEVER RE3UIRE CIRCUIT BREAKERS,WHICH ARE MORE ROBUST & CAPABLE OF BREKING THE LARGE VALUEOF FAULT POWER THAT RESULTS IN FAULTS ON MAJOR POWER SYSTEM.SINCE ALL PLANTS AND LINES ARE LIABLE TO DEVELOP FAULTS AS ARESULTS OF MECHANICAL DAMAGE, ELECTRICAL BREAKDOWN,ERRORS IN OPERATION 46. THE SIMPLE ISOLATORS SWITCH IN FAVOUROF AUTOMATIC CIRCUIT BREAKERS EVEN FOR SWITCHING FUNCTION.THE WHOLE SWITCHGEAR ASSEMBLY CONSISTS OF TWO PARTS>*

A.%AEL* PANEL CONSISTS OF PROTECTIVE RELAYS,MOUNTIG OFPOTENTIAL TRANSFORMER,CURRENTTRANSFORMER,AMMETER,VOLTMETER & ENERGY METER. THEPOTENTIAL TRANSFORMER IS MOUNTED ON THE PANEL. THE PRIMARYIS CONNECTED TO 11KV & THE REDUCE VOLTAGE FROM THESECONDARY IS GIVEN TO ENERGY METER AS LINE VOLTAGES & FORPROTECTIVE PURPOSES.

.!R0LL6* THE TROLLY CONSISTS OF CURRENT CARYING CONTACTSCALLED ELECTRODES. THESE ARE NORMALLY ENGAGED BUT INPREDETERMINED CONDITIONS, SEPARATE TO INTERRUPT THE CIRCUIT,WHEN THE CONTACTS ARE MADE.

A LIGHTING ARRESTER IS DEVICE, WHICH PROVES LOWIMPEDENCE PATH FOR THE FLOW OF CURRENT BETWEEN THE LINE

AND EARTH WHEN THE SYSTEMS VOLTAGE INCREASES MORE THAN THEDESIRE VALUE AND REGAINS ITS ORIGINAL PROPERTIES OF ANINSULATOR AT NORMAL VOLTAGE. IT IS CONNECTED BETWEEN LINE

AND EARTH AT THE SWITH YARD NEAR THE TRANSFORMER.

THE LIGHTING ARRESTERS ARE E'TENSIVELY USED FOR PROTECTIONOF TRANSFORMERS, SWITH GEARS AND ELECTRICAL E3UIPMENTS OFOVER HEAD LINES, POWER HOUSES AND SUB*STATION . THESE ARE
