Asymmetry is defined as follows: max{|Vph-ph|} nom. voltage when measuring phasephase voltages and also as follows: 2 max{|Vph-n|} nom. voltage when measuring phase-neutral voltages. If the asymmetry exceeds the set level the red LED starts flashing 2 Hz and the output relay releases after the set time period. If the phase sequence is incorrect or one phase is lost, the output relay releases immediately. Only 200 ms delay occurs. The failure is indicated by the red LED flashing 5 Hz after the alarm condition occurs. Example 2 (load monitoring) Example 1 (mains network monitoring) The relay releases in case of interruption of one or more phases or when the asymmetry exceeds the set level. The relay monitors asymmetry, phase loss and correct phase sequence.
