The Importance of Safety Capacitors in Power Electronics

Y Capacitors: Class-Y capacitors, also known as "line-to-ground capacitors" or "line bypass capacitors," offer line-to-ground protection, which generally means that if a failure with the ground occurs, there is a risk for shock. However, Class-Y safety capacitors must meet rigorous specifications, minimizing the chance of electric shock.

What are the risks of a power capacitor failure?

VI. Risks when a fault occurs circuit power. uncontrolled release of this energy. This systems containing several capacitor units due to possible avalanche effects. 2. Power capacitors can actively fail when internal or external protective devices are missing, incorrectly dimensioned or have failed.

Are self-healing capacitors the same as fail safe system stability?

The so-called self-healing capability is not the same as fail safe system stability. 4. Most internal protective devices can inter-rupt the voltage only within the capacitor. They are not fuses in the classical sense such as cable or device fuses which inter-rupt the voltage upstream from the faulty system component. 5.

Are power capacitors dangerous?

When power capacitors are used, suitable te possible danger to humans, animals and property both during operation and when a failure occurs. This applies to capacitors both with and without protective devices. Regular inspection and maintenance by a competent person is therefore essential.

Can a capacitor be stored in a corrosive environment?
