Capacitor assembly and maintenance

How to perform preventive maintenance on capacitor banks?

The document describes the procedure to perform preventive maintenance on capacitor banks. The procedure includes identifying the equipment, performing a general cleaning, checking the electrical connections, checking the condition of the components, and testing operation before putting them back into service.

How to measure the capacitance of a capacitor?

Measure #1 – Verify proper mechanical assembly of the capacitor units, clearances as per the electrical code, and soundness of the structure of all capacitor banks. Measure #2 – It may be useful to measure the capacitance of the banks and keep the measurements as benchmark data for future comparison.

What standards are applicable to the production and inspection of capacitors?

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.

What is a capacitor repair procedure?

The procedure includes identifying the equipment, performing a general cleaning, checking the electrical connections, checking the condition of the components, and testing operation before putting them back into service. The objective is to identify possible faults and ensure that the capacitor banks are working correctly.

How do I know if my capacitor bank Assembly is good?

Each capacitor bank assembly shipped is in good condition when it leaves the factory. Immediately upon receipt of a capacitor bank shipment: Check each capacitor nameplate to make sure the rating is correct for the application. Check the bank and each capacitor case and bushing for signs of rough handling and shipping damage.

How do I ensure a safe use of CLMD capacitor units?

For a safe use of CLMD capacitor units, please ensure − Installation and maintenance are undertaken only by authorized and qualified personnel, in ac-cordance with current local regulations; − Isolate the equipment from the supply before at-tempting to gain access.
