GENERATOR EFFICIENCY
Generator Efficiency is ratio between power output and power . Efficiency can be written as :
LOSSES TYPE
1COPPE
R LOSSE
S
2IRON LOSS
ES
1HYSTER
ESIS LOSSES
2EDDY
CURRENT LOSSES
LOSSES IN GENERATOR
Copper Losses is the power lost in the form of heat in the armature winding of a generator
Iron Losses is the power lost in the form of heat in iron core of a generator
Iron Losses divide into : 1.Hysteresis Losses is a heat loss caused
by the magnetic properties of iron core2. Eddy Current Losses is a heat loss
caused by current conductor of iron core
