General Safety Recommendations for Power Capacitors

Capacitors must never be stored or used outside the specified temperature ranges. Capacitors may not be stored or operated in corrosive atmospheres, particularly not when chlorides, sulfides, acids, alkalis, salts, organic solvents or similar substan-ces are present.

Capacitor Bank Maintenance

y Visually inspect the capacitors. y Check the protection fuse. y Control the ambient temperature (average of 35 °C. In accordance with IEC 60831). y Control the service voltage (especially during moments of low load, it must not exceed the nominal +10%) y Carry out a dielectric rigidity test by applying 2.5 kV for 1 second between the terminals of the capacitor and earth. y Check the

General Safety Recommendations for Power Capacitors

These safety recommendations and requi-rements apply to the following power capa-citors and standards. Their purpose is to. 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.

Inspection and maintenance of capacitor banks (recommended

Standard safety practices should be followed during installation, inspection, and maintenance of capacitors. Additionally, there are procedures that are unique to capacitor banks that must be followed to protect field operators and equipment in accordance with the NESC – National Electrical Safety Code.
