GB/T 17627-2019High-voltage test techniques for low-voltage equipment - Definitions, test and procedure requirements, test equipment (English PDF)

1 Scope

This standard specifies.

--- Definition of terms for general applicability and specific applicability;

--- General requirements for samples and tests;

--- Test voltage generation and measurement methods;

--- test procedures;

--- Evaluation methods and acceptance criteria for test results;

--- requirements for accredited measuring devices and their verification methods;

--- Measurement uncertainty.

Note 1. Refer to Appendix A and Appendix B for examples of measurement uncertainty and evaluation.

If alternative test procedures are used, they should be prescribed by the relevant technical committee.

It is worth noting that if the test product contains a pressure limiting device, its test results may be affected, and the relevant technical committee should be responsible for this type of test product.

Provide technical guidance.

This standard applies to DC and AC electrical equipment with AC rated voltage not higher than 1kV, or DC rated voltage not higher than 1.5kV.

Current, impact insulation test and test equipment.

Relevant technical committees may perform type tests and routine tests of low-voltage electrical equipment that have high-voltage test requirements specified in this standard.

The test equipment includes a voltage generator and a measurement system.The measurement equipment in the measurement system should be able to avoid external

Interference and coupling, a simple comparison test is sufficient to ensure that its measurement results are valid.

This standard does not apply to electromagnetic compatibility tests for electrical or electronic equipment.

Note 2. For the combined test of impulse voltage and current, refer to GB/T 17626.5.
