A Training Presentation On 132 KV GSS JAIPUR Submitted in partial fulfillment For the award of the degree of BACHELOR OF TECHNOLOGY Submitted To:- Submitted By:-

INTRODUCTION 132KV GSS HINGONIA INSTALLED IN 1993 THIS GSS SUPPLIED FROM RAINWAL AND THIS GSS FEED CHAMPAPURA THE TOTAL CAPACITY OF THIS GSS IS 80MW IN AMP. ABOUT 320AMP THERE ARE 11 FEEDERS 4 FEEDER 33KV 7 FEEDER 11KV

 FEEDERS  BUSBARS  CIRCUIT BREAKERS  TRANSFORMERS  LIGHTNING ARESSTER  ISOLATERS  PLCC SYSTEM  CAPACITOR BANK  BATTERY CHARGER & CONTROL ROOM CONTENTS:

FEEDERS 33 KV FEEDERS:- * KHEJRAWAS * LALPURA * MUNDOTA * KARANSAR

* HNG VILLAGE * GUDAMAN * BHAINSAWA * MURLIPURA * DUNGRI * BASSI NAGA * HINGONIA(HNG) 11KV FEEDERS:-

A bus bar is a conducting bar that carries heavy currents to supply several electric circuits. When a no. of generators or feeders operating at the same voltage level to be directly connected electrically, busbar are used as the common electrical component. Capacity is 80MW of this GSS There are two types of busbars:- o Main busbar o Auxiliary busbar BUS BAR SYSTEM

A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit A ckt breaker essentially consists of fixed & moving contacts, called electrodes under normal operating conditions, these contacts remain closed & will not open automatically until & unless the systems becomes faulty. CIRCUIT BREAKER

SF6 CIRCUIT BREAKER

Transformer is an electrical machine which works on the principle of electromagnetic induction. It transfers electric power from one electric ckt to other with the help magnetic path(flux) on constant frequency but equal or different current voltages. TRANSFORMER

132/33 KV TRANSFORMER

C.T. is an instrument transformer used for protection & metering of high values of currents. C.T. is used for reducing ac from higher to lower value for measurement/protection/control. There are two classes of C.T:  protective C.T  measuring C.T CURRENT TRANSFORMERS

CURRENT TRANSFORMER

Potential transformers are instrument transformers. They have a large number of secondary turns and a fewer number of primary turns. They are used to increase the range of voltmeters in electrical substations and generating stations POTENTIAL TRANSFORMERS

A lightning arrester is a device used on electrical power systems and telecommunications systems to protect the insulation and conductors of the system from the damaging effects of lightning LIGHTNING ARRESTER

Isolators are designed to open a ckt under no load. Its main purpose is to isolate portion of ckt from the other & is not intended to be opened while current is flowing in the line. There are two types of isolators:-  off load isolators  on load isolators ISOLATERS

For exchange of dates and transfer message between grid substation, voice communication is necessary. for this purpose high frequency carrier current is transmitted on same transmission line on which power is transmitted. Hence such communication is called “power line communication POWER LINE CARRIER COMMUNICATION

Capacitor banks are used to improve the quality of the electrical supply and the efficient operation of the power system. Studies show that a flat voltage profile on the system can significantly reduce line losses CAPACITOR BANK

In a GSS, Separate dc supply is maintained for signaling remote position control, alarm circuit etc. There is a battery room which has 55 batteries of 2 volt. CONTROL ROOM AND BATTERY CHARGER
