Power Quality Analyzer CW500

Published on : Tuesday 30-11--0001

The Yokogawa CW500 is a portable power meter that utilizes current clamp-on probes, navigation screens and quick start guides. These features enable user-friendly power consumption and power quality measurements in the field that conform to IEC61000-4-30 Class S.

Key Features

• Power Measurement and Logging
• Power Quality Measurement
• User Support
• Analysis of Data and Report Generation

Power Measuring and Logging

    Simultaneously measures 3 CH Voltage input, 4 CH current clamp probe input, 2 CH DCV input.

    Instantaneous/Average/Maximum/Minimum value list or trend graph screen of Voltage/ Current/Power/Power factor/Phase Angle/Phase Advanced Capacitance Calculation.

    Integration Value of Active/ Reactive/Apparent Energy is each displayed consumption and generation.

    Demand monitoring which displays screens of present power consumption compared to aimed demand power values.

Power Quality Measuring

Measure Temporary Malfunctions of the Power Line

• The CW500 captures temporary malfunction phenomena of the power line that can cause malfunction or destruction of devices due to voltage swell, voltage dip, interruption, transient voltage over, and inrush current by using a high sampling rate of 24 µs and RUS calculation.
• Event data contains the type of malfunction, occurred time or occurrence finish time, measured value and waveform of voltage and current of all channels for approx. 200 ms period.
• This measurement method conforms to IEC standard  61000- 4-30 Class S

Measure Continuous Malfunction of the Power Line

Harmonics

• Measure and display graphs and lists of up to the 50th  Harmonic components of voltage, current, and power for each phase and total.

Flicker

• Measures 1-minute flicker (Pst, 1 min), short flicker, (Pst) and long flicker (Plt).

Unbalance rate

• Displays voltage and current unbalance rate on 3 phase wiring.

It is used in Electrical Industries.
