POWER FACTOR CONTROLLER
1.General Features
The Power Factor Controller PFC 9055 measures the power
factor (cosφφ
φφ
φ) and reactive power (kVAr) of power system and displays
them on a digital display. The power factor controller performs the
automaticconnectionanddisconnectionofcapacitorsinfunctionofthepower
factor and set point programmed.
Designed with latest state of art technology using micro controller, the
power factor controller becomes an intelligent equipment, able to
accurately measure the power factor and to take complex decisions for
switching on/off the capacitors.
The power factor controller performs the true R.M.S measurement of
reactive power and power factor including harmonics. The power
measurement is done for the full four quadrants. The power factor is
displayed on a 12.5 mm high visibility red LED display. Four keys are
provided on the front panel for programming purpose.
The power factor controller is provided with 12 output relays with the
possibilityof an additional alarm relay. Thepower factor controller is housed
in a PVC enclosure with the dimension of 144(H)x144(W)x150(D) mm
Installation
General consideration
The meter is panel mountable and fits into a cut out of 138 X 138 mm
dimension. Place the meter through the panel cut out and fix the mounting
clamps provided with the meter on each side of the meter. Tighten the fixing
clamps with limit amount of force so as to hold the meter firmly.
The power factor controller is used to measure power factor, when
mounted in instrument panels and is to be installed only by trained
electricians and technicians. The PT’s and CT’s used for measurement
should be of instrument class 1 or better for accurate measurement
results. Also PT’s and CT’s should have adequate VA rating to support the
burden on the secondaries.
