    Power Management
    Geetech is a company specialized in energy metering and
    partner for your energy consumption monitoring system.

    Energy is a precious good which is becoming always more
    important in all different sectors.  Attention is more and more
    focused on energy costs and there is a growing interest
    to avoid energy waste. Energy measurement and analysis
    allow the user to monitor and manage the energy consumption
    and the relevant costs, resulting in a read and effective quality
    and money saving.  the soft ware and analyzers are the
    appropriate solution both for basic measurement and complete
    comprehensive energy management system.


  • Real Time data viewing of  electrical  parameter
  • The value can be displayed numerically, graphically
    or on a trending and  moving chart. Location of devices
    on a synoptic table.
  • Creation of measured data archives.

    The remote connection can be set by RS 232/485 serial line,
    or by Ethernet/ Internet net works, Modem, Wireless system
    and etc..

    Answer  1

    Your meter measures kW, not kvar, it ignores the power factor. Correcting the power factor will make very little difference since the
    only power saved will be the small amount of loss in the cables. Connecting capacitors may actually make this loss larger since
    the capacitive current will flow continuously.


    Answer 2

    Capacitors will improve your power factor only if your present load is quite inductive. Typical inductive loads include incandescent light bulbs,
    and motors (including forced air heating / cooling fans, refrigerator compressors, chest freezer compressors, dehumidifier compressors etc.)

    If your load is already capacitive, adding more capacitors will only make your power factor worse.

    One way to figure out what your present power factor is, is to view the incoming voltage waveform (240V) with an appropriate probe attached
    to channel 1 of an oscilloscope, and attach a current clamp to the incoming line on channel 2 of the scope. Compare the phase difference
    of the two waves, and convert to an angle Take the cosine of the angle to find your power factor. Ideally, it should be 1.

    If the voltage waveform leads (rises before) the current waveform, your load is inductive, and a capacitor will help.

    If the voltage lags the current, a capacitor is not recommended, as your load (house) is already capacitive.

    Don't try these measurements unless you take appropriate safety precautions, and know what you're doing.

    Alternately, you could request the VAR (volt-amp-reactive) numbers for each major appliance from their manufacturers, and calculate
    your load without coming anywhere near 120 or 240VAC.
