Specification

Measures

  • 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.
