Creepage distances, i. For example, rail-mount terminal block designed to operate 800 nominal voltage usually tested using 2000 alternating voltage for one minute. The insulation material the housing may car- bonized creeping current, which further increases conductivity.g.20 www. T: Time interval for calculating the rate rise T1: Front time (duration between start impulse and reaching the peak) T2: Total pulse duration The test values are the values sea level specified the relevant test specification. Apart from the amount impurities which terminal block subjected, for example, the plastic material and housing design are also involved generating creeping currents.

This test verifies the clearances product. The arrangement the rated impulse withstand voltage test identi- cal that the power frequency withstand voltage test; the test voltages, however, are comparatively higher and the testing times shorter, e
