Manometer
It is a pressuremeasuringinstrument, usually limited
to measuring pressures
near to atmospheric.
The term manometerisoften used to refer
specifically to liquid column
hydrostatic instruments.

AUTOMATIC CONTROL SYSTEM
LAB
Deals in automating the equipments and feedingroutes.
Provides safe operation under all plant disturbancesand component failures.Requires 24 Volt DC, 4-20 mA to excite all the
controls.System installed in BTPS is OLD RUSSIAN
SYSTEMS.
These are ACS (Automated Control System) which

PROTECTION &
INTERLOCKING LAB
Interlocking : It is basically inter-connecting two ormore equipments so that if one fails other can perform
the task.
Main Equipments of this lab:oRelays
oFusesoCircuit Breakers

Relays
It is a protective device.It can detect wrong condition in electrical circuits by
constantly measuring the electrical quantities flowingunder normal and faulty conditions.
Types:oCurrent Relay
oPotential Relay

Fuses
It is a sheet piece of metal.It melts if a heavy current flows through it and
breaks the circuit.Usually silver is used as a fuse material.Types:o
Semi Enclosed Rewire able FuseoH.R.C Cartridge Fuse
oMiniature Current breakers

FURNACE SAFEGUARD
SUPERVISORY SYSTEM
In this lab, fuel firing system is monitored in thefurnace.
Oil is sprayed first for firing of coal in furnace soLight Diesel Oil (LDO) is used for ignition.The rate of oil flow is 6000 L/hr before firing.
