6 Frequently Asked Questions about “Fire protection level of indoor capacitors”
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.
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.
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.
