4.2 Transformer
Alll checks and insulation measurements of transformers must be
performed according to the instructions of the transformer
manufacturer.
Note that the I/O interface to the converter will be tested later.
Checking of the transformer includes the following:
• Insulation resistance
The insulation resistance must be measured or the confirmation of
the measurement must be obtained.
• Oil quantity, in case of oil type transformer
Oil quantity can be checked on the oil level gauge located on the oil
expansion vessel.
• Valves between transformer tank and radiator
All valves must be in open position to allow free oil flow between
tank and radiators.
• Condition of dehydrating breathers.
• Sense of rotation of fans and pumps (if applicable).
• Protection devices of transformers
Will be checked together with the external signals of the ACS 6000,
see Chapter 8 - Checking I/O, 8.3.2 Transformer Signals.
• Cleanness, rating plate values and thermal protective devices of
dry-type transformers (ABB Resibloc)
Follow the checkpoints of the commissioning report.
4.3 Motor
All checks and insulation measurements of the motor and its auxiliary
systems must be carried out according to the instructions of the motor
manufacturer.
Checking of the motor includes the following:
• Insulation resistance
The insulation resistance must be measured or the confirmation of
the measurement must be obtained.
• Oil quantity.
• Visual check of electrical and pneumatic instrumentation.
