Siemens SINAMICS G150 - Insulation Test; High-Voltage Test

3.5 Insulation test
3.5.1 High-voltage test
Fundamentals
The test is carried out according to the following standards:
● IEC 61800-5-1
● IEC 62103
● For marine applications, additional requirements from the marine classification societies
may apply.
The high-voltage test verifies the voltage strength (test voltage) for overvoltage conditions
specified in the standard.
Test equipment
A calibrated test instrument is used for the test.
Test procedure
1. The circuits to be tested are separately short-circuited corresponding to the individual
voltage levels.
– Power circuit/circuits
– Various auxiliary circuits
2. The circuits that are presently not connected to the test instrument are connected to ground
potential.
3. The test voltage is adjusted for each circuit corresponding to the insulation test report.
4. The circuits are tested with respect to one another and with respect to the PE protective
conductor at the electrical cabinet.
The test duration is 1 s, for marine applications, 60 s.
5. The test is repeated with 80% test voltage.
Result
The test is passed if the test instrument is not switched off (tripped) during the test as a result
of flashover.
