Applications

  • Measure Temporary and Continuous Malfunction of Power Line

    Captures temporary malfunction phenomena of power line which causes malfunction or destruction of devices by types
  • Measure Continuous Malfunction of Power Line Harmonics, Waveform, Flicker and voltage and current unbalance rate on 3 phase wiring

  • Analysis of Data and Report Generation

  • Detect voltage fluctuation

    When trouble occurs on supply side of electric power, instantaneous voltage drop can affect quality of produced goods at the factory. The CW500 is useful for collecting data such as voltage fluctuation to prevent such problems.

Description

The Yokogawa CW500 is a full-function power quality analyzer with features that include power measuring and logging (one-phase two-wire to three-phase four-wire), power quality measuring (voltage swell, voltage dip, voltage interruption, transient overvoltage, inrush current, harmonics, and flickers), user support (start guide function and automatic detection of current clamp probe), and data analysis and report generation (single-click creation of graphs and reports of measured data).

IIII [+] Read More
Applications/major target markets include power and energy measurement for power plants, automated factories, offices, and commercial facilities as well as power quality measurement for inspecting and troubleshooting power lines of assets where there are concerns of voltage swells, voltage sags, voltage dips, voltage interruption, inrush currents, harmonics distortion, and flicker.
