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.

Testing capacitors is essential to prevent equipment failure and ensure system reliability. A faulty capacitor can cause significant operational downtime or even damage other components,
Begin with a visual inspection. Look for any signs of physical damage, such as bulging, leakage, or discoloration. These visual cues can indicate a capacitor in distress. Use a digital multimeter to measure
Visual inspection is another effective diagnostic tool for assessing capacitor health. Observable signs like bulging, swelling, or electrolyte leakage are clear indicators of internal failure modes, often resulting from excessive pressure within the casing. Swollen capacitors will appear convex or domed, rather than flat, signaling internal gas buildup due to
There are three types of test performed on capacitor banks. They are. Design Tests or Type Tests. Production Test or Routine Tests. Field Tests or Pre commissioning Tests. When a new design of power capacitor is launched by a manufacturer, it to be tested whether the new batch of capacitor comply the standard or not.

Conclusion: Proper inspection and maintenance of capacitor banks are essential to ensure their safe and efficient operation. Adhering to industry standards and best practices, along with periodic inspections and measurements, helps identify potential issues early on, reducing the risk of accidents and maximizing the bank's lifespan.
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:
Visual inspection of the capacitor bank must be conducted for blown capacitor fuses, capacitor unit leaks, bulged cases, discolored cases, and ruptured cases.
In making this evaluation, consideration must be given to the sensitivity of capacitor bank protection (such as unbalance protection) and the potential for a capacitor under test to inadvertently discharge stored energy into a protection system. In most cases secondary isolation of the protection system will be required.
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
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.
