Variable Frequency Drives (VFDs) keep industries moving. From manufacturing plants and HVAC systems to water treatment facilities and food processing lines, these drives are the backbone of efficient motor control. But what happens when a VFD sits unused for months or even years?
The answer is hidden inside the drive: its electrolytic capacitors.

Why Capacitor Reforming Matters
Electrolytic capacitors store and filter energy within a VFD, ensuring stable, efficient operation. However, when idle for long periods, their oxide layer weakens. This silent breakdown can lead to leaks, shorts, or even catastrophic failure once the drive is powered on again.
Capacitor reforming provides the solution. By applying a controlled voltage, the process rebuilds the oxide layer, restoring the capacitor to like-new condition without costly re-placement.
It is not just a good idea; it is a best practice. Major OEMs such as ABB, Siemens, and Rockwell Automation recommend reforming VFD capacitors if equipment has been stored for more than one to two years.
