ABB TB840A 3BSE037760R1 best quality one year warranty
By means of accurate hardware design and by using an efficient directional algorithm a high sensitivity
for the voltage sensing circuit and a high accuracy for phase angle measurement are
achieved so that a correct directional decision can be made even by close three-phase faults.
As an addition, to avoid maloperations due to disturbances, at least 2 periods (40 ms at 50 Hz) are
evaluated.
