6 FAQs about [Capacitor Device Safety Measures]
Do capacitors need external protective devices?
Particularly with sensitive applications, the internal protective devices of the capacitors must be supplemented by the user with suitable external protective mea-sures. External protective measures are even mandatory when capacitors are used without internal protective devices.
Can internal protective devices interrupt a capacitor?
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. It is advisable to supplement internal protective devices with external protective 6.
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.
How to choose a capacitor?
safety and quality should be the top priori-ties when a capacitor is selected. This is why we urgently recommend the use of capacitors with appropriate internal pro-tective devices. 2. Before designing the application, capaci-
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.
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.
