Insulation test

3.4.1

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
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
2. The circuits that are presently not connected to the test instrument are connected to ground
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
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.
