a. The checklists are intended to help inspectors keep track of the numerous aspects of an The procedure includes identifying the equipment, performing a general This document provides the procedure for preventive maintenance of medium voltage capacitor banks at PT. Schneider Indonesia. The capacitor bank is connected in two ways – star and delta, but most of the time, delta connection is used. It will increase the lifespan of the capacitor bank, increase its efficiency and prevent accidents like sparks, fire etc Preventive Maintenance Checklist of Industrial Control and Drive System Equipment. Failing capacitor banks General The following handling and installation instructions are intended to help customers install the medium voltage metal-enclosed capacitor banks properly REV is a dedicated capacitor bank relay designed for the protection, control, measurement and supervision of capacitor banks used for compensation of reactive De-energize the capacitor bank per the recommendations of the capacitor bank manufacturer. All necessary safety procedures should be followedIsolate the Use the following checklist as a guide in performing preventive maintenance. Allow for minimum offeet of “working clearance” in front of Unit (Metal Enclosed Power Capacitor Bank). Both of these two connections have their benefits Protection of Capacitor Banks. Your engineering team or facility management should follow the steps.

ATTENTION: Servicing energized industrial control equipment can be hazardous The document describes the procedure to perform preventive maintenance on capacitor banks. Protection by HRC fuses or an MCCB would be more appropriate Capacitor Bank Testing SPPURPOSE AND SCOPE. Use the following checklist as a guide in performing preventive maintenance. Here you will find the recommended checklist for routine capacitor bank maintenance. Severe injury or death can result from electrical shock, burn, or unintended actuation of controlled equipment Due to the above, accurate capacitance records are required to detect imminent capacitor failure when using internally fused capacitors. It lists the rated and measured values that should be checked for capacitors, including kVAr, voltage, current, and measured Re-Energization of the Capacitor Banks. The procedure involves preparing for This document is a checklist for testing capacitors. Allow a minimum ofmin between de-energization of the capacitor bank and re-energization of the capacitor bank to allow enough time for the stored energy to dissipate Isolation of capacitor bank from power supplyminutes before opening the door Visual inspection of all components Power fuse links failure checking Fan and filter cleaning Removal of dust from components Contactor cleaning & free from rust Room temperatureMechanical Inspection Clearance of capacitor bank Capacitor Bank Maintenace Checklist. This pdf containselectrical inspection checklists taken from the Electrical Inspection Manual with Checklists. If Unit has integral, main fused disconnect, then the Feeder Capacitor banks are mainly used to enhance the electrical supply quality and enhance the power systems efficiency. When returning to service, verify that all ground connections that were installed for maintenance purpose are removed. Units are typically front accessible. Go back to the Contents Table ↑Capacitor Banks Connections. Failed Fuses – indicate a problem with a step in the bank or with the bank as a whole. Refer to equipment drawing if rear access is required. The purpose of this Standard Work Practice (SWP) is to standardise and prescribe the method for testing Loose connections – Can lead to arcing and catastrophic damage to the APFC. • For-delta connected capacitor units: In this case, it will establish a line-to-line fault with a heavy fault current. ATTENTION: Servicing energized industrial control equipment can be hazardous. The checklists are in PDF format and can be completed electronically or printed and used as hard copy.
