Bushing creep distance
WebAug 11, 2024 · To help mitigate that risk, there are standards for two primary spacing measurements in your PCB design: clearance and creepage distance. When the voltage between two points overcomes the breakdown voltage, arcing can occur, damaging your product creating a safety hazard for users. http://www.composite-insulator.com/FAQ/protected-creepage-distance.html

WebThe creepage distance for arresters, shown in table 7, should be similar to that of all insulators on the system to which it will be applied. Often for coastal or high-pollution areas, extra creep units are used. The definition of creepage distance is shown in figure 4. 1.2/50μs Impulse WebAug 11, 2024 · Since moving tracks is rarely the first choice, there are a couple other tricks for increasing the surface distance in your design. By adding either a slot between tracks, or a vertical barrier of insulation, you …
WebAvailable at 50 or 60 Hz, their ratings are calculated according to the voltage level of the transformer they are connected to (i.e., 10%). Voltage level ratings for 1-phase voltage regulators vary between 2.5kV and 19.9 kV and between 31.8kVA and 889kVA. 3-phase units are available at 13.2kV, 34.5kV, or from 500kVA up to 4,000kVA.
