After a capacitor bank is de-energized, there will be residual charges in the units. Therefore, wait at least 5 minbefore approaching it to allow sufficient time for the internal discharge resistors in each capacitor unit to dissipate the stored energy. These resistors are designed to reduce the voltage across the individual.

Conduct a thorough inspection of mechanical assembly, clearances, and the overall structure of the capacitor bank before returning it to service. Test all controls, load breaks, disconnects, and grounding switches to ensure proper operation. Periodic Inspection and Measurements:
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.
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.
Visual inspection of the capacitor bank must be conducted for blown capacitor fuses, capacitor unit leaks, bulged cases, discolored cases, and ruptured cases.
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
