6 FAQs about [Capacitor maintenance principles]
How to perform preventive maintenance on capacitor banks?
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.
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.
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.
What is a capacitor repair procedure?
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. The objective is to identify possible faults and ensure that the capacitor banks are working correctly.
How much MVAR should a capacitor bank have?
0% to +5% for capacitor banks above 30 MVAr. These are usually HV capacitor units/banks: for capacitor units or banks containing one ±7.5% unit per phase ±5% for capacitor banks less than 30 MVAr ±3% for capacitor banks 30 MVAr and above.
Does a capacitor need protection?
As discussed in the previous chapters, a capacitor may have to encounter many unfavourable service conditions when in operation. Most of them may lead to its direct over-loading. Summing up all such conditions, a capacitor would need protection against the following:
