ISO 9001 certified, highly qualified specialists:
high pressure cleaning
components testing
coolers and flanges inspection
stator and rotor rewinding
vacuum pressure impregnation (VPI)
final tests and measurements
All High Voltage AC stators repaired by our Company undergo strictly the following tests according to VDE 0530 and IEC-34 specifications:
Magnetic induction measurements on stator iron core to detect the existence of any hot spots. If any hot spots are detected then we proceed with their total elimination
Megger tests between phases and ground
Megger tests between phases
Dielectric strength tests by applying 2Un+1000 Volts for one minute between phases and ground
Polarisation Index and Absorption Factor Tests
Capacitance measurement on each phase
Dissipation factor losses (tangent delta)
Ohmic resistance on each phase
Routine tests after order, provided the whole motor is received
