B.H.E.L . AN OVERVIEW
BHEL’s first plant was set up in BHOPAL in 1960’s 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 14 manufacturing 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
dc magnetizing current to the field windings of a synchronous generator thereby ultimately inducing 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
TYPICAL VIEW OF BLES
DIFFERENCE B/W BTES AND BLESS.No BTES BLES
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
