To the production and inspection of the capacitors, the standards (VDE [German Association for the Electrical, Electronic, andInformation Technologies] and IEC provisions and requirements) that, unless otherwise explicitly agreed upon by the parties, are effective at the time of the order confirmation will apply.
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.
describe the state of technology which must as a rule be adhered to in all relevant contracts for goods and services. II. General safety rules Since power capacitors are electrical energy storage devices, they must always be handled with caution.
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-
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.
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.
