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.
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.
Overload prevention in any given design is serious business, which means that the choice of safety capacitor shouldn’t be taken lightly either. Areas to consider in the decision process include safety requirements, type of filtering, the pros and cons of different device types, the consequences of device failure, and much more.
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.
This article describes methods to identify hazards and assess the risks associated with capacitor stored energy. Building on previous research, we establish practical thresholds for various hazards that are associated with stored capacitor energy, including shock, arc flash, short circuit heating, and acoustic energy release.
Since safety capacitors operate directly connected to the mains, they have to meet the requirements of the IEC 60384-14 safety standard. The safety requirements are much higher for Y capacitors, because a short/failure of such a component could present an immediate danger of an electric shock (see below). 3.
