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

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.

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 d 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.
