Circuits and equipment are generally classified as ‘high voltage’ when they have a nominal voltage exceeding 1000 volts AC or 1500 volts DC. High voltages are generally found in the electrical distribution network where it is common to see systems operating at 11,000 VAC, 33,000 VAC, 132,000 VAC and even 400,000 VAC.
WebA high voltage surge generates turn to turn, coil to coil, and phase to phase voltage stress, as well as ground insulation stress. When used as a dielectric test, accurate voltage readings are essential. The HV Surge Tester monitors the voltage directly across the winding under test. WebTest voltage levels are either calculated using a multiple of the cable's nominal phase-phase voltage or via tables in IEEE 400.2; typically they are in the range of 1.5 U0 to 3 U0. ... the IEEE 400.3 outlines a procedure for assessment and IEC 60270 provides the background for partial discharge testing of high voltage apparatus. The test is ...
