This document provides the procedure for preventive maintenance of medium voltage capacitor banks at PT. Schneider Indonesia. The procedure involves preparing for maintenance by obtaining permits and assembling tools. The main power is then isolated by switching off the main supply panel and installing locks and tags.
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.
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).
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.
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.
Allow a minimum of 5 min between de-energization of the capacitor bank and re-energization of the capacitor bank to allow enough time for the stored energy to dissipate. 5. Initial Inspection Measurements and Energization Procedures
