High voltage bushing creepage distance
WebJun 28, 2024 · In high voltage circuits where the voltage is above 30VAC or 60VDC, creepage and clearance spacing rules must be observed to prevent unintentional arcing between two conductors. Often, these two measurements are the same, as the distance between two component pads or other exposed areas of metal on an unobstructed … WebA UHV bushing is more than 10 m long, and even a maximum of 15 m. Its mechanical performance should not only meet the normal environmental requirements but also …
High voltage bushing creepage distance
Did you know?
WebCreepage distance is defined as the shortest path over the surface between two conductive parts, which is related to the tracking failures. The generation of a conductive path along the isolator surface due to the high voltage applied over a long time is more related to the RMS or DC value, and depends on environmental conditions. WebJun 19, 2024 · for creepage and spacing calculation IEC/UL based calculator2. When I change parameters (pollution, material, etc) it gives the same creepage distance value for all the cases. I 'm not sure it could be a good thing. When I use creepage calculator 1 for 1000V it gives me different values comparing with the calculator 2 using the same parameters.
