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

8/22/2019 presentation for electrical engineering in ntpc

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.
