• Power Factor Protection or Compensation Control
• Lead (CAP) and Lag (IND) relay outputs
• Linear to Phase Angle
• Optional very fast analogue output signal proportional to Meter reading (<50mS), (F-version)

Description
The KPPF3x measure the power factor in single phase or balanced 3-phase systems.

The unit gives analogue indication of power factor and has 2 relay outputs and a optional analogue output signal proportional to meter deflection 0,5 CAP / 1 / 0,5 IND (F-version).

These output relays are configured for one in the lead sector and one in the lag sector. These can be used to control power factor compensation equipment or control and AVR via a suitable motorised potentiometer.

Zone 2 is the normal operational range. In zone 1, the load is capacitive and the trip value of the LEAD relay can be set over the range 1-0,5 LEAD. In zone 3, the load is inductive and the trip relay of the LAG relay can be set over the range 1-0,5 LAG. Both relays have an adjustable time delay of 30 seconds.

Red relay trip lamps flash instantly (approx. 1 flash per second) on passing a trip. The lamp changes state and the trip relay operates after the pre-set delay. If a trip condition ends during the delay interval, the timer will automatically reset.
