6 FAQs about [Capacitor Quality Inspection Notes]
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 is a visual inspection of a capacitor bank?
Visual inspection of the capacitor bank must be conducted for blown capacitor fuses, capacitor unit leaks, bulged cases, discolored cases, and ruptured cases.
How to measure the capacitance of a capacitor?
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. Measure #2 – It may be useful to measure the capacitance of the banks and keep the measurements as benchmark data for future comparison.
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
Do capacitor banks need maintenance?
Capacitor banks generally require very little maintenance because they are static type of equipment, but don’t be fooled by this statement. Capacitors are well known for their dangerous reaction when something goes wrong. Standard safety practices should be followed during installation, inspection, and maintenance of capacitors.
How is the finish of film capacitors assessed?
The finish of film capacitors is assessed in compliance with EPCOS finish specifications. For more detailed specification, refer to the "General technical information" chapter. When applicable, the individual data sheets are definitive for finishing. The failure rate is defined as the failure percentage divided by a specified operating period.
