Generator stator and generator cable
Check the insulation of the generator stator and cable as follows:
• Check that all cables are disconnected from the converter output terminals U2, V2 and
W2.
• Measure the insulation resistance between each phase conductor and the protective
ground conductor using a measuring voltage of 1000 V DC. The insulation resistance of
an ABB generator must exceed 100 Mohm (reference value at 25 °C (77 °F)). For the
insulation resistance of other generators, please consult the manufacturer’s instructions.
•
Note:
Make sure that there is no condensed moisture inside the generator casing. If you
suspect that there is moisture, dry the generator before measurement.
•
Note:
When using permanent magnet generator, it must be stable at the time of the
measurement.
