Visual inspection of the capacitor bank must be conducted for blown capacitor fuses, capacitor unit leaks, bulged cases, discolored cases, and ruptured cases.
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.
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.
Safety First, adhering to Standard Practices: Installation, inspection, and maintenance processes must all be strictly followed over the whole lifespan of a capacitor bank. Protecting field workers and equipment requires adherence to pertinent standards like the NFPA 70E and the NESC (National Electrical Safety Code).
The Factory Acceptance Test (FAT) procedure for Low Voltage (LV) switchboards entails checking the design and functionality prior to installation. Inspections, functional testing of components & systems, and assuring specification and standard compliance are all part of the process.
