Visual inspection of the capacitor bank must be conducted for blown capacitor fuses, capacitor unit leaks, bulged cases, discolored cases, and ruptured cases.
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:
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.
related to the starting of the motor defined in IEC 60644. The capacitor bank protection fuse-links are described in IEC 60549 (High-voltage fuses for the external protection of shunt capacitors) . Also in this case the fuse should meet the requirements described in the general standard IEC 6028
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.
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
