Stator Core Testing

The document discusses EL CID testing which is used to test the insulation of stator cores in electric generators. EL CID testing identifies damage to the insulation and localization which can reduce outages. Common causes of stator core damage include physical impacts, plate relaxation, loose components, foreign objects, thermal effects, and insulation failures.

Stator Core Testing

Dedicated People, Quality Products, and Above All, Service

ELectromagnetic Core Imperfection Detection (EL CID)


is the comprehensive method of testing the interlaminar
insulation of the stator core. When eddy currents are
elevated, hot spots appear in the stator core that may
cause deterioration of the core lamination insulation. If
the hot spots are not discovered, permanent damage
may occur to the stator winding insulation and core iron.
EL CID testing identifies and localizes existing damage
that reduces planned or forced outages.
Advantages
Setup time and safety hazards are greatly reduced
over the traditional high current loop ring flux
testing
Identifies further damage
Reduces safety hazards
Extremely low excitation power demand
Causes of Stator Iron Core Damage
Physical damage caused by the rotor core
Compression plate relaxation
Loose bars and wedges
Foreign magnetic objects
Thermal core creeping
Interlaminar iron core insulation failure
Oil contamination
Incorrect wedging
