Impulse Current Generator
Impulse current generators are primarily used to test the ability of electrical equipment to withstand surge currents stably. They are widely used for energy and residual voltage tests on valve-type units of zinc oxide surge arresters and entire surge arresters, for surge current testing of meteorological lightning protection equipment, and for model testing of aircraft lightning current resistance.
Functions
The impulse current generator can produce standard 1/20 μs steep-front currents, 4/10 μs high-current pulses, 8/20 μs standard currents, 18/40 μs and 30/80 μs operating currents, 10/350 μs, 2000 μs long-duration square-wave currents, 3200 μs long-duration square-wave currents, 6400 μs long-duration square-wave currents, and 200–230 μs half-wave near-sinusoidal currents, A, B, C, D, and H current waves for aircraft models. The waveform technical specifications comply with national and IEC standards. The product has passed ministerial-level appraisal, and its key technical performance is at the forefront domestically, reaching the technical level of comparable international products.
