6 FAQs about [Fire protection requirements between capacitors]
Should a capacitor test be based on a standard?
Even if the test based on the capacitor standard is passed, this does not ensure comprehensive protection against all pos-sible overloading. Currently, a number of customers are requesting special tests on unprotected capacitors with extreme overvoltages and temperatures to prove safe capacitor per-formance.
Why do I need a special test on unprotected capacitors?
Currently, a number of customers are requesting special tests on unprotected capacitors with extreme overvoltages and temperatures to prove safe capacitor per-formance. or their behavior in the event of a fault. perature) should be monitored within the application. 8.
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.
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.
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.
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.
