Rack-mounted Power Transducers 17-RACK

VAR TRANSDUCER

Functions & Features

• Providing a DC output signal in proportion to AC reactive

power

• DC output containing little ripple is ideal for computer

input

• "Time division multiplication" method accepts distorted

waveforms

Typical Applications

• Centralized monitoring and control of power management

system in a manufacturing facility or building

■ How To Determine Var Range

Calibration Range [var] = (Measuring Range) ÷

((VT Ratio) × (CT Ratio))

Check that the required calibration range is within the

available range in the table.

[example]

3-phase / 3-wire, measuring range 75 kvar,

VT 220 / 110 V, CT 250 / 5 A
