Analysis and Report of recorded data

Demand measuring

Demand is the average power value of a specic period
(usually 30 minutes). Contract with the power supplier
conditionally concerns the maximum average power value
between 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 specic period

When the estimated demand
value line is displayed inside
this area, it mean that the
demand value will be over the
target value.

Analysis and report is enabled by simply clicking on the
desired data on software screen.
Analysis is capable by trend graph, average, maximum and
minimum value of voltage, current, power, power factor.
Report generating could be set by day time, night time,
working day, off day or monthly period.
Additionally energy data to quantity of crude oil barrels, or
to CO

can be converted.

Power Quality Function

Short period power line malfunctions such as voltage swells/dips/interruptions/transient overvoltage or inrush currents, or
long period such as harmonic distortion, icker may damage or reset your devices.
The CW500 helps to identify each of those short period malfunctions, by recording occurrence time, occurrence nish time
and waveforms. Additionally there is a digital output on occurrence.
Long period malfunctions can be analyzed by harmonics, icker, waveform or checking on the unbalance rate calculation
for 3 phase measurement.
All data can be nalized to a report format with included software.
The CW500 conforms to the IEC standard of 61000-4-30 Class S.

which are used for the control circuit of general devices
could affect currents and cause harmonic distortion.

Heavy loading on a specic phase, could inuence

Examination of main power line quality for
factory system control and assets

• Conrm to check quality of power line for factory system

control and assets.

• Simultaneously measure the consumption of energy

trend and consider solutions for energy saving.

CW500 not only continuously measures harmonics
but captures malfunction of power line and records
occurrance time with waveforms. Simultaneously it can
measure power and leakage current of neutral phase.
Additionally users can conrm the condition of assets
