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

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
