  • Specification


    • Voltage
    • Current
    • Active power
    • Reactive power
    • Apparent power
    • Power factor
    • Frequency
    • Current flowing on the neutral line (Only on 3 phase 4 wire measurement)
    • Active power energy
    • Reactive power energy
    • Apparent power energy
    • Demand measurement

    Transients / Over Voltage (Impulse)

    • Can Set Detecting Level Value (Threshold Value).
    • Easy-to-Use Checking the Occurrence data On The Display.
    • Arises from defective contact etc. of Breakers, Magnets and Relays.
    • Reaches highest value (peak value) of voltage in a very short time from inputting voltage and this is a unipolar type voltage change (Spike) that attenuates slowly.
    • Destroys the instrument’s power source and causes reset action due to sudden voltage change (Spike).

    Inrush Current

    • Can Set Detecting Level Value (Threshold Value).
    • Easy-to-Use Confirming the Occurrence data On The Display.
    • Large current (Surge current) flows transiently at the time of starting of instruments etc. which have built-in motor, incandescent lamp, larger capacity smoothing condenser.
    • Causes bad effect to power switch's welding, fusing, breaker’s trip and converter circuit etc. and also causes unstable power voltage.

    Harmonics Analysis

    • Can Measure and Analyze from 1st to 63rd Harmonics.
    • Harmonics Contents (THD: Total Harmonics Distortion Display)
    • Can Judge Inflow / Outflow.
    • Can Set Detecting Level Value (Threshold Value).
    • Control circuits of instruments use inverter circuit (condenser input type converter circuit) and thyristor control circuit (phase control circuit). These circuits cause distortion in the current. The distortion causes harmonics.
    • Causes burning of phase advance condenser and reactor, beat of transformer, wrong way of breaker, flicker of TV image, noise of audio players etc.

    Swells / Dips / Instantaneous Stop

    • Can Set Detecting Level Value (Threshold value).
    • Easy-to-Use Confirming the Occurrence data such as Swells/Dips/Instantaneous Stop on the Display.Cause of Swells (Voltage rise)
    • Voltage rises instantaneously by Inrush Current caused at the time of power input of the power line switchgear.
    • Voltage drop happens by Inrush Current caused at the time of starting of load of motors etc.
    • Power supply stops instantaneously due to thunderbolt etc. (Under 1 sec.) (Interruption of Service > Power supply stop more than 1sec.)
    • Stops operation of instruments / welding robots and causes reset of OA appliances like PC.

    Unbalance Rate

    • One Touch Switch to Vector display and Power display
    • Easy-to-Use Confirming Phase angle difference thanks to Vector display
    • Specific Phase gets over loaded due to fluctuation of power line load and unbalanced equipment built. These cause distortion of voltage / current, voltage drop and antiphase voltage.
    • Causes unbalance of voltage / current, uneven turning of motor, antiphase voltage, harmonics etc.
