Reforming a capacitor
Web11. jún 2013 · If you want to keep the look the best is to remove the old capacitor, gently open it ( or not so gently in some cases) and remove the dead foil and paper insides. Then clean it, dry it and put a modern replacement inside the old case, close it up after connecting the new leads to the old case parts. place back in the equipment and enjoy. WebBus Capacitors For drives that are in storage and do not have voltage applied, maintenance of the capacitors in the drive can be required. Follow these requirements and the guidelines listed in Table 3 for bus capacitor maintenance and reforming: • The reforming voltage must be 1.35…1.45 times the rated AC system voltage
