Undercurrent Protection In 5th Harmonic Filter
Undercurrent Protection In 5th Harmonic Filter
(OP)
Is anyone able to explain the purpose of undercurrent protection in a 5th harmonic filter.
With reference with the attached schematic, why are the highlighted CTs installed in the resistance circuit of the filter and why would a low current in this circuit cause a fault condition? Is it just to ensure that the resistors have not opened circuited?

Again, ff the installation is un-attended, better trip rather than going unattended!
