Potential Hazards Of High-voltage Disconnect Switches

Many people are unaware that, despite its crucial function, improper operation can still have serious consequences.

High Voltage Disconnect Switch does not have arc-extinguishing capabilities. This means that when switching under load, an electric arc can rapidly form under high voltage once the contacts separate. As the arc continues to burn, its heat and electrical energy accumulate rapidly, increasing the arc length and potentially crossing the insulation distance between devices, causing a short circuit or equipment damage. Excessive arc energy can even trigger an explosion, posing a significant threat to the surrounding environment and personnel safety.
