WitrynaFor impulse tests, impulse voltage of the prescribed magnitude as per specifications is applied, and the cable has to withstand five applications without any damage. Usually, after the impulse test, the power frequency dielectric power factor test is done to ensure that no failure occurred during the impulse test. Partial Discharges: WitrynaAir-Insulated Switchgear – AIS. Proudly manufactured in Lake Mary, Florida, our medium voltage air-insulated switchgear provides safe, reliable switching and fault protection. JST Power Equipment type J100CLAD™ is an IEEE-rated, non-arc-resistant, metal-clad switchgear product line with Type J3MAG™ vacuum circuit breakers. WitrynaThe ratio of breakdown voltage for any insulation or gap due to an impulse voltage of specified t1 / t2 or shape to power frequency breakdown voltage is defined as impulse ratio. For a 1.2/50 μs wave t1 =1.2 μs and t2 =50 μs. For a sphere gap, where the electric field is uniform at the gap, the impulse ratio is unity. design your house software
