AI Customer ServiceUndervoltage conditions can lead to machinery malfunction or failure, impacting the entire production line. Advanced undervoltage protection systems detect such conditions early and
AI Customer ServiceUndervoltages come from drop of power supply voltage during surges. The easiest solution is to set undervoltage paramater [FUV] to a lower value and use power supply that doesn't shut down or drop to near zero under power surges. For very short current surges (millisecond range), an added capacitor to HV DC bus might provide a solution.
Operating a high voltage capacitor at lower dc voltage cause some low continuous current to flow through the capacitor, thus rendering the capacitor not behaving ideally as a capacitor. The voltage rating of the capacitor is the point at which the dielectric & insulation between the two plates starts to break down and fails.
Undervoltage happens when the average voltage of equipment falls below the rated voltage amount. Frequent undervoltage can result in a degradation in equipment performance and reliability. The winding suffers a substantial amount of wear and tear in the winding and reduces the lifespan of the equipment. Why?
Rule of thumb round here is that caps rated for 2x the working voltage is a good (reliable) part. You tend to find more like the opposite. A high voltage capacitor will have it's capacitance rated at low voltage meaning when operated close to it's rated voltage the capacitance will be much lower.
In addition to these failures, capacitors may fail due to capacitance drift, instability with temperature, high dissipation factor or low insulation resistance. Failures can be the result of electrical, mechanical, or environmental overstress, "wear-out" due to dielectric degradation during operation, or manufacturing defects.
A leaky capacitor has the effect of a large rated capacitor that leaks and keeps the circuit from working properly. In most cases, you can over rate a capacitor and get away with it. If you double the voltage value of the capacitor but keep the supply voltage low you might want to also double the Farad value.
