Ten faults of capacitors(9)

When the capacitor bank adopts fuse protection (the drop fuse must be used, the capacitor itself is affected by a barrier or overvoltage of the system, etc., all of these will make the capacitor bank fuse. Once the capacitor fuse a wire, it will cause the three-phase current indication to be out of balance.

Solution: first identify the fuse phase and capacitor number, and then check. The appearance of the capacitor has the phenomenon of bulging, whether oil seepage, whether the casing has flashover discharge trace, then the occurrence of 'time, phase, capacitor number and observed phenomena are reported to the dispatch, all according to the dispatch order.
