Power Quality Measuring

Measure Temporary Malfunctions of the Power Line

Voltage/Current/Power (Active, Reactive, Apparent)/Power Factor/ Phase Angle/Frequency/Calculated Phase Shift Capacitance/DC voltage value 2 CH.

Integration Value

Energy (active, reactive, apparent), Demand (list or graph display of change in a specific period and as a whole)

Recording Interval Period

1/2/5/10/15/20/30 second, 1/2/5/10/15/20/30 minute, 1 hour/2 hours

Recording method

Manual, time, period

Estimated Recording Length with 2 GB SD card

• The recording length shortens according to the number of power quality events.

• Only the included SD memory card or dedicated SD memory card is guaranteed.

Various Measuring Screens

List display, zoom display by 4 or 8 divisions, trend graph display, integration value display for energy, demand list display of value, demand graph display for change of period, demand graph display for whole recording

List Display

Items of measured values can be selected with the curser key.

Zoom Display

Zoom display can be selected by 4 or 8 divisions. 

Trend Graph

Trend graph of voltage/ current/power/power factor/frequency/ advanced phase condenser external DC voltage.

Energy Display

List of active, apparent, reactive by consumption or generation.

Demand measuring

Demand is the average power value of a specific period (usually 30 minutes). The contract with the power supplier conditionally concerns the maximum average power value between a period for the consumption fee. This function supports how to maintain within the target consumption by monitoring the estimated demand value to the setting rate with the maximum demand value.

List of Demand Value

Graph display of change on specific period

Graph display of whole demand trend

Analysis and Reporting of recorded data

Analysis and reporting is enabled by simply clicking on the desired data on the software screen.

Analysis can be viewed by trend graph, overage, maximum and minimum value of voltage current, power, and power factor. Report generating can be set daily by daytime, nighttime, working day, or off day. It can also be set on a monthly period based on daytime or nighttime, working day or off day. Additionally, energy data to quantify into crude oil barrels or CO2 can also be converted.

Power Quality Function

Short period power line malfunctions such as voltage swells, dips, interruptions, transients, over or inrush currents, or long periods of harmonic distortion/flicker may damage or reset your devices.

The CW500 helps to identify each of those short period malfunctions by recording occurrence time, occurrence finish time and waveforms. Additionally there is a digital output on occurrence.

Long period malfunctions can be analyzed by harmonics, flicker, waveform, or by checking on the unbalance rate calculation for a 3 phase measurement.

All data can be finalized into a report format with the included software. The CW500 conforms to the IEC standard of 61000-4-30 Class S.

User Support Function
