INTRODUCTION
KSTPS is first coal based power plant in Rajasthan.
It is located ideally on the left bank of CHAMBAL
River at the upstream of KOTA BARRAGE.
Its first unit of capacity 110 MW is synchronized on 17
jan 1983.
It is one of highest power generating plant with
installed capacity of 1240 MW.

COAL HANDLING PLANT
Is called the HEARTof thermalpower plant because it provided thefuel for combustion in boiler.
The coal is brought to the KSTPSfrom BHARAT COAL LTD.
There are 14 tracks fortransportation.
Everyday 3- 4 trains of coal areunloaded, each train consists 58wagons.
Coal is unloaded from wagons bymeans of WAGON TRIPPLER

TURBINE
Turbine is a machine in which a shaft is rotated
steadily by impact of steam it converts heat
energy into mechanical energy.

SWITCHYARD
The 220 KV Switch yard is the main part of the KTPS
it has two buses arrangement with a bus coupled breaker.
There are 11 feeders connected at 220 KV switchyard

CIRCUIT BREAKER
Circuit breaker is basically a mechanical device used
to make or break an electrical circuit under normal &
abnormal condition.
A circuit breaker is switched on or off under loadconditions an arc is produced in between the breaker
contacts.
This arc produced between the breaker contacts is
quenching by some suitable medium.

TYPES OF CIRCUITS BREAKER
MINIMUM OIL CIRCUIT BREAKER SF6 CIRCUIT BREAKER
In M.O.C.B separating contact of the
breakers are made to separate within
an insulating oil.
In SF6 separating contact of the
breakers are made to separate within
SF6 material.

ISOLATORS & ARRESTORS
Isolators are device which disconnect the instruments
from power supply, the isolators provided at 220 KVswitchyard are motor operated.
Lightening Arresters are used in switchyard for preventingfrom Lightening phenomena and are installed at entranceof switchyard.

CURRENT TRANSFORMER
Current transformers are provided for measuring
and protection. All Current Transformers at 220KV switchyard are BHEL manufactured .
Designed to provide a current in its secondary coil
proportional to current flowing in its primary coil.
Primary winding consists of very few turns.
Secondary winding consists of large no. of turns
Current to be measured is passes through
primary winding.
8/22/2019 Presentation r5
20/24
POTENTIAL TRANSFORMER
Used for the measurement of high voltages.
Primary winding is connected to voltage to be
measured.
Voltmeter is connected across the secondary
winding.
