SUMMARY
INTRODUCTION The creation of Uttar Pradesh Power Corporation Ltd.
(UPPCL) on January 14, 2000 is the result of power sector reforms and restructuring in UP (India) which is the focal point of the Power Sector, responsible for planning and managing the sector through its transmission, distribution and supply of electricity.
For efficient operation & management Uttar Pradesh Power Corporation Limited (UPPCL) is further restructured into:-
Dakshinanchal Vidyut Vitaran Nigam Limited (DVVNL) - Agra Zone Madhyanchal Vidyut Vitaran Nigam Limited (MVVNL) – Lucknow
Zone Pashchimanchal Vidyut Vitaran Nigam Limited (PVVNL) - Meerut
Zone Purvanchal Vidyut Vitaran Nigam Limited (PUVVNL) - Varanasi
Zone Kanpur Electricity Supply Company(KESCO) - Kanpur City Lucknow Electricity Supply Administration (LESA) - Lucknow City Uttar Pradesh Power Transmission Limited (UPPTCL) - State

132 kV substation KASIAIt is divided into two parts:-
A. Panel Section Control Panel Section Relay and Protection Panel Section
B. Switch Yard
132kV section 33kV section
C. Battery Room (Extra)
A. Panel Section It is a room which contains all types of panels. It has two sections:-
Control Panel SectionIt contain panels related to controlling of instruments. E.g.:- feeder panel, transformer panel, etc.
Relay And Protection Panel SectionIt contains panels related to relay systems and protection systems. E.g.:- Relay panel, line protection panel, etc.
B. Switch Yard It is the field where components used in controlling
supply and measuring supply(incoming and
outgoing) are placed.Some of these components are:-
C.Bs Isolators C.Ts P.Ts L.As Transformers, etc.

-EQUIPMENTS - LIGHTENING ARRESTER- Protect the Insulation & Conductors
of the system from damaging effect of LIGHTNING
CAPACITIVE VOLTAGE TRANSFORMERStep down extra high voltage signals.
Provide a low voltage signal.
For MEASUREMENT of voltage.
To operate a protective relay.
WAVE TRAP (PLCC)POWER LINE CARRIER COMMUNICATIONExchange of data and transfer of messages between substations.
WAVE TRAP-TRAPPING the unwanted waves.
ISOLATORS Used for completely DE-ENERGISED the electrical circuit for SERVICE
or MAINTENANCE. Separate the circuit at NO LOAD CONDITION.
INSTRUMENT TRANSFORMERS
INSTRUMENT TRANSFORMERS are used for measurement and protective
applications together with equipments such as meters & relays
Types-
A) CURRENT TRANSFORMER B) POTENTIAL TRANSFORMER
CIRCUIT BREAKER
Automatically Operated ELECTRICAL SWITCH.Designed to protect the ckt. from overload
or SHORT CKT.Separate Healthy & Faulty Section of ckt.
Operate at ON LOAD Condition.
VACUUM CIRCUIT BREAKERS Vacuum circuit breakers are circuit breakers which are used to protect medium and high voltage circuits from dangerous electrical situations
AIR-BLAST CIRCUIT BREAKERFast operations ,suitability for repeated operation , auto reclosed , unit type multi break constructions ,simple assembly , modest maintenance are some of the main features of air blast circuit breakers. A compressors plant necessary to maintain high air pressure in the air receiver.
TYPES OF CIRCUIT BREAKERS
OIL CIRCUIT BREAKERA high-voltage circuit
breaker in which the arc is drawn in oil to dissipate the heat and extinguish
the arc; the intense heat of the arc decomposes the
oil .SULPAR HEXAFLUORIDE CIRCUIT BREAKER (SF6)
Sulpharhexafluoride (SF6) gas is used as the arc
quenching medium . The SF6 is an electronegative
gas and has a strong tendency to absorb free
electrons. Circuit breakers have been developed for
voltage 115KV to 230KV , power rating10 MVA
BUS BAR
A bus bar is a conducting bar that carries heavy currents to
supply several electric circuits.
Made up of copper rod or thin walled tubes.
TYPES:-
- MAIN BUS BAR.
- AUXILIARY BUS BAR
POWER TRANSFORMER
A Static Device.
Transfer Power from One circuit to another circuit
No Change in FREQUENCY.
Principle-FARADAY ’s LAW of ELECTROMAGNETIC INDUCTION.Types- 1. STEP UP TRANSFORMER::
O/P Voltage > I/P Voltage.
2. STEP DOWN TRANSFORMER ::
O/P Voltage < I/P Voltage.

core Winding(H.V winding, L.V winding,
tertiary winding) transformer OILS PRESSURE RELIEF VALVE BREATHER Conservator RADIATER Tap changer Tank
Protective Relay is a sensing device and is designed to detect
operating conditions on an electric
circuit.
It trips the circuit breaker when fault is detected.
PROTECTIVE RELAYS
TYPES OF RELAY Overcurrent relay Differential relay Tripping relay Directional Relay Auxiliary Relay
A gas actuated relay.
it is installed in b/w the conservator and the main tank.
PRINCIPLE:- Whenever a fault occurs inside the transformers, the oil of the tank gets
overheated and gases are generated. The heat generated by the high local current causes
the transformer oil to decompose and produce gas which can be used to detect the faults.
BUCHHOLZ RELAY
BATTERY ROOM
DC battery shell be installed in the power house for
Emergency power.
Protection.
Alarm and indication.
TRANSFORMERSAlso known as the heart of substations. These are used to reduce the voltages at appropriate levels
CURRENT VOLTAGE TRANSFORMERSIt is a used in power systems to step down extra high voltage signals and provide a low voltage signal, for measurement or to operate a protective relay
WAVETRAPTraps the high frequency signalsISOLATORS
Used for maintenance of the circuit in no load
condition
CIRCUIT BREAKER used to protect the
equipment by opening the circuit for over
current and over voltages
LIGHTINING ARRESTER
Used for protecting the equipment from surge
voltages
