6 FAQs about [Energy storage insulation withstand voltage test]
What is the withstand voltage test for Basic insulation?
According to International Electrotechnical Commission (IEC) 60950, the withstand voltage test for basic insulation is 2U + 1,000 VRMS, where U is the maximum operating voltage of a system. A manufacturer may need to apply a 4,242-V withstand voltage test when designing an 800-V system based on Equation 1:
What is a passing grade insulation?
A measured insulation post-test that meets the manufacturer’s requirement threshold is considered a passing grade. According to International Electrotechnical Commission (IEC) 60950, the withstand voltage test for basic insulation is 2U + 1,000 VRMS, where U is the maximum operating voltage of a system.
What is a dielectric voltage withstand test?
Safety standards require that manufacturers evaluate the effectiveness of a given electrical or electronic device’s insulation for safety by performing a dielectric voltage withstand test (also called a high-potential test). The dielectric voltage withstand test applies high voltages across the insulation barrier for one minute.
Do insulation characteristics affect high-voltage dielectric withstand testing?
Insulation characteristics have consequences for high-voltage dielectric withstand testing: internal insulation does not require special test conditions where, for example, the environment has to be taken into account. In case of self-restoring insulation, breakdown may occur during HV tests.
What are withstand voltage tests?
Several kinds of withstand voltage tests are conducted as type tests for high-voltage equipment to validate the dielectric performance. These tests consider various kinds of voltage stresses imposed on the equipment in operation. Testing voltages are defined in the standards.
How does a test voltage break down a insulating material?
Simply stated, the test voltage breaks down the insulating properties of the material. The mechanism of dielectric breakdown begins with the application of a strong electric field to the insulating material by a high voltage. Different materials require different levels of electric field in order for dielectric breakdown to occur.
