Capacitors | Environmental Health and Safety | Virginia Tech

Capacitors may store hazardous energy even after the equipment has been de-energized, and may build up a dangerous residual charge without an external source. "Grounding" capacitors in series, for example, may transfer (rather than discharge) the stored energy.

Overheating and Fire Hazards in Capacitor Banks

Moreover, the capacitor lifetime depends directly on the operating temperature hence an overheating will lead to a faster aging. The main reason for a burning or even exploding capacitor bank is the liquid-filled capacitors, or the plastic parts that are combustible. If the temperature rises, the capacitor can cause a fire, a life-threatening

6 FAQs about [Occupational hazards of aging capacitors]

How does aging affect capacitor performance?

What are the aging laws of aluminum electrolytic capacitors?

Aging laws of electrolytic capacitors. Many techniques deal with life forecast and failure detection of aluminum electrolytic capacitors which are utilized as a part of power electronic converters. The main idea of these techniques is to estimate the values of Equivalent Series Resistance (ESR) and Capacitance (C).

Are electrolytic capacitors aging?

Since the development and production of electrolytic capacitors, designers have had to deal with the issues of aging and shelf life of these products. Electrolytic capacitors have been around for a very long time, but the rapid increase did not occur until the 1960s.

How many capacitors are used in the accelerated aging study?

A total of 47 capacitors under test are used for this accelerated aging study. Measurements using an impedancemeter are done periodically during the accelerated aging test to characterize the frequency response of the capacitor’s impedance.

What factors affect the lifetime of electrolytic capacitors?

Therefore, the major factors affecting the lifetime of electrolytic capacitors in the power applications will be the operating temperature, the ripple current and the operating voltage. Other factors have minor affect to the lifetime and can be ignored in the calculation. 1. Influence of temperature on the lifetime model

What causes an electrolytic capacitor to fail?

An electrolytic capacitor has several failure modes and causes. Electrical, thermal, mechanical, and environmental stresses cause the degradation of this component. The main failure mechanism is the evaporation of the electrolyte, which is accelerated with temperature rise during the operation, mainly due to ripple currents.
