Controlling
Simple controlling 3-phase (3-phase capacitors), max. 15 switching outputs. For 3-phase-
measurement: controlling is done either according to the worst cos
φ
or average value.
For single-phase-measurement: 2 current inputs are additionally available for measured capacitor
bank currents
Single phase controlling: max. 5 switching outputs for each phase (3 · 5 switching outputs); each
phase is controlled separately. Single phase capacitors are switched to neutral.
Mixed controlling: e.g. 3
·
3 single phase capacitors per phase (L-N) for balancing and additional
6 outputs for normal 3-phase-capacitors.
Separate controlling of single phase capacitors L-L (without neutral)
