Capacitor banks protection, cautions and maintenance tips
Under minor fault conditions, gases are released within the capacitor element to effectively weld and close any hole caused by the dielectric fault. Under major fault conditions, the gas is released with such force that the capacitor disconnects itself from the supply before further damage is caused by raising the top of the preformed canister and mechanically …
