High-voltage cables, insulators and bushings are critical components in power transmission and distribution systems. Their insulation performance must be evaluated using the test procedures and acceptance criteria applicable to each product type.
An impulse voltage test system can generate specified high-voltage impulse waveforms for applicable insulation tests. System configuration depends on the rated voltage, electrical characteristics of the test object, required impulse waveform, connection arrangement and measurement requirements.
For insulator testing, an appropriate steep-front impulse attachment may be considered when required by the test procedure. Other applications may require different measuring arrangements or accessories.
Some configurations may cover multiple applications, but compatibility must be verified individually for each test object and procedure.
No. It is only required for specific tests that call for steep-front waveforms, such as certain insulator tests.
Provide the cable type, rated voltage, required test waveform, applicable standard, termination arrangement and other relevant test parameters.
This depends on the measuring and software configuration. Specify the desired report format and waveform data requirements in advance.
