Testing Methods
EL CID
to detect failures between laminations of stator cores
RSO Testing
to test both the turn and ground insulations of generator rotors
IMCA (Induction Motor Current Analyser)
to test for cracked rotor bars while machines are running in service
Insulation Resistance
testing of all electrical equipment before any high voltage testing is commenced
Partial Discharge Analyser
to test the condition of a machines insulation by measuring the levels of partial discharges at operating voltages
Tan Delta Testing
Main cell wall insulation of all coils above 4.0v AC are tested using an inductively coupled capacitive bridge to measure tan delta
TVA Probe Testing
to locate areas of localised discharge within the stator slots of high voltage stators
Underwater Testing
can be used after the VPI (Vacuum Pressure Impregnation) Process before being returned to site.
