6 FAQs about [Electricity costs caused by failure of compensation capacitor]

What causes a capacitor to fail?

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.

Why do electrolytic capacitors fail more often than not?

Electrolytic Capacitor Life is nicely identified by chem-con.com . In a nutshell, they fail more often then not because of excessive temperature. Secondary and more predictable are voltage, high duty cycle, etc.

Can a capacitor be mechanically destroyed?

A capacitor can be mechanically destroyed or may malfunction if it is not designed, manufactured, or installed to meet the vibration, shock or acceleration requirement within a particular application. Movement of the capacitor within the case can cause low I.R., shorts or opens.

What happens if a capacitor leaks?

If the internal pressure becomes great enough, it can cause a breach in the capacitor, which can then cause leakage of impregnation fluid or moisture susceptibility. The epoxy seals on both epoxy encased and wrap and fill capacitors will withstand short-term exposure to high humidity environments without degradation.

Why do paper and plastic film capacitors fail?

Paper and plastic film capacitors are subject to two classic failure modes: opens or shorts. Included in these categories are intermittent opens, shorts or high resistance shorts. In addition to these failures, capacitors may fail due to capacitance drift, instability with temperature, high dissipation factor or low insulation resistance.

What causes a capacitor to change capacitance?

Changes in capacitance can be the result of excessive clamping pressures on non-rigid enclosures. (See Technical Bulletin #4). As the temperature of a capacitor is increased the insulation resistance decreases.
