6 FAQs about [What are the capacitor forming treatments ]
How are capacitors reformed?
Capacitors are reformed via a composition of a rectifier and a resistor circuit, which is connected to the converter DC link. The reforming circuit is shown below. Component values for different voltages are given in the table below. See the reforming time from Figure 1. WARNING!
What is the correct course of action for electrolytic capacitors?
The correct course of action is to ensure that each electrolytic capacitor’s insulation layer is ‘reformed’ by the application of a current and voltage limited DC supply to each individual capacitor. Current limiting ensures that the heat generated within the capacitor is kept at a sufficiently low level that damage does not occur.
What is a capacitor reforming voltage?
Capacitor reforming is based on DC power supply, which is connected to the drive input. The power supply current charges drive capacitors. If the power supply cannot limit the current, the voltage is increased gradually (with e.g. 100V steps). The maximum recommended reforming current is 100mA. An appropriate reforming voltage is (1.35 2) * Ux.
How to reform a capacitor based on a DC power supply?
Capacitor reforming is based on DC power supply, which is connected to converter DC link. Power supply current charges the converter capacitors. If power supply cannot limit the current, voltage is increased gradually (with e.g. 100 V steps). Maximum recommended reforming current is 500 mA. An appropriate reforming voltage is (1.35
Does reforming a capacitor fix a problem?
If there are any visible signs of failure of a capacitor (leaks, etc) you should replace it; reforming will not fix those problems. Reforming is a preventative measure to potentially reverse natural deterioration in the capacitor. Reforming does not “fix” capacitors, it just prevents potentially healthy capacitors from failing
Do you need a capacitor reforming schedule?
A rigorous schedule for reforming capacitors should be incorporated in your facility maintenance schedules. This will prevent damage to spares and intermittently idle plant systems. Manufacturers of drive and other power supply equipment that uses large electrolytic capacitors include capacitor reforming schedules in the applicable documentation.
