- How long do brushes last in VARIAC transformers? How often should they be inspected?
Typical brush life in most applications is several years even with heavy usage. Operation for many years with the original brushes is not unusual.
Periodic brush inspection is recommended depending on use and environment. For most applications once per year is sufficient. Applications where the brush is in constant movement, operated with repeated periodic overloads and/or operated at high ambient temperatures may require more frequent inspections.
