KPPF3x - POWER FACTOR (COS PHI) GUARD
- 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.
The unit meets EN 61010-1 Cat. III, Pollution degree 2 and the relevant
environmental and EMC tests specified in EN 61326-2-4 to comply with the
requirements of the major Classification Societies.
