B.H.E.L . AN OVERVIEW

BHELs first plant was set up in BHOPAL in1960s under Indo-Soviet agreement.

BHEL is the largest engineering and

manufacturing enterprise in India. It has been earning profits continuously

since 1971-72.

The wide network of BHEL has 14manufacturing division, 150 project sites,

eight service centers and 18 regional

offices.

BEARINGS

Bearing is a machine element which support another

moving element (journal).

TYPES OF BEARINGS

1.Sliding contact type 2.Rolling contact type

EXCITATION SYSTEM

It is the power source that supplies the dcmagnetizing current to the field windings ofa synchronous generator thereby ultimatelyinducing ac voltage and current in the

generator armature.Types of excitation system

Rotating exciters

1:-Brush Type 2.Brushless Static exciters

1.Shunt Type 2.Series Type

1.Requirments

2. Maintenance

3.Operation

4. Efficiency

Require slip-rings commutators

and brushes

periodic maintenance required

More noise operation

Gives little discrimination in

efficiency

Do not require slip-rings

commutators brushes

Practically maintenance free

Less noise operation

Gives Better efficiency
