Has anyone had experience with anti-windmilling devices fitted to motor shafts ? We are having serious problems with standby fans running in reverse when duty fans are on. Then if standby fan is called for the starting / braking current created trips the crrent protection on overcurrent.
Any...
Can anyone recommend a tester that can be used on any 3 phase system motor, prior to startup, so that wrong phase direction and rotation of shaft is eliminated ??
