(1) Hazards to Power Capacitors When there is a harmonic in the power grid, the terminal voltage increases after the capacitor is inserted, and the current through the capacitor increases more, which increases the power loss of the capacitor. For film-membrane composite dielectric capacitors, although the power loss when harmonics are allowed is 1.38 times the power loss without harmonics, the power loss when harmonics are allowed for all-film capacitors is 1.43 times that without harmonics, but if Higher harmonic content, beyond the capacitor allowable conditions, will make the capacitor over-current and overload, the power loss exceeds the above value, so that the capacitor abnormal heat, the insulation medium under the effect of the electric field and temperature will accelerate aging. Especially when the capacitor is put into the power grid where the voltage has been distorted, the harmonic of the power grid may also be exacerbated, that is, the phenomenon of harmonic expansion occurs. In addition, the presence of harmonics tends to make the voltage appear sharp. The steep-peak voltage wave easily induces partial discharge in the medium. Due to the large voltage change rate and partial discharge intensity, it can accelerate the aging of the insulating medium, thus shortening it. The service life of the capacitor. In general, for every 10% increase in voltage, the life of the capacitor is reduced by about 1/2. In addition, in the case of severe harmonics, the capacitor will bulge, breakdown or explosion.
