Thermal Management of Electrolytic Capacitors
In many current applications, however, the internal temperature requirements have been ignored: many times the capacitor banks are so densely packed that the capacitor bodies are touching. Even though the capacitor specifications usually require a 1" spacing, the demand for smaller packages overrides the capacitor''s need for cooling.

6 FAQs about [Capacitor on-site management requirements]
What safety practices should be followed during installation and maintenance of capacitors?
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.
What are the maintenance requirements for a capacitor bank?
Maintenance Requirements: Regular maintenance is necessary to ensure the long-term reliability of capacitor banks. This includes periodic inspections to check for signs of wear or damage, such as bulging capacitors or leaking dielectric fluid.
What should be taken before energization of capacitor banks?
Initial Inspection Measurements and Energization Procedures During the initial inspection before energization of the capacitor banks the following measures should be taken: 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.
Why is sizing a capacitor important?
Proper Sizing is Crucial: Accurate power factor analysis and reactive power assessment are essential for effective capacitor bank performance. Maintenance is Key: Regular inspection and timely maintenance help mitigate issues such as overvoltage and harmonic distortion.
How long does it take to re-energize a capacitor bank?
When returning to service, verify that all ground connections that were installed for maintenance purpose are removed. Allow a minimum of 5 min between de-energization of the capacitor bank and re-energization of the capacitor bank to allow enough time for the stored energy to dissipate. 5.
How often should a substation and distribution capacitor bank be inspected?
The substation and distribution capacitor banks should be inspected and electrical measurements be made periodically. The frequency of the inspection should be determined by local conditions such as environmental factors and type of controller used to switch the capacitors on and off. 7. Visual Inspections
