The CW240 power meter is a complete tool for enhancing energy efficiency, finding areas for improvement and assessing equipment lifecycles. The meter provides in-depth information on how an item of equipment, an area of a plant or a complete facility is operating that goes beyond simply measuring power usage.
By using the supplied clamp-on components and probes, users can better determine maintenance, repair and replacement schedules for equipment such as transformers and motors. Information is provided with respect to load factors and demand factors, as well as current/voltage fluctuations at motor start-up.
The CW240 offers many unique features to improve energy efficiency through highly detailed data collection and easy-to-understand displays.
Measurement of Instantaneous Values
Better determine the maintenance, repair and replacement schedules for each piece of electrical equipment, such as transformers and motors, by analyzing detailed information with respect to load and demand factors. Review detailed information on current and voltage fluctuations at motor start-up.
Perform data collection at intervals from 60 times per second to hourly in order to cover every application in the plant from low interval (e.g., plant watt hours) to high interval testing (e.g., troubleshooting a motor)
Data Collection Time(s):
Power Quality Measurement
Improve power measurment and data collection for compliance with ISO14001 and other standards by showing exactly how and when power is being used. Power measurement is broken down into individual phases to provide a more comprehensive view of overall power usage.
Data Collection Time(s):
The CW240 also provides real-time and data log capabilities that are seamlessly downloadable into an available software package that can display graphs, trends and reports.
Select the Number of Display Digits and Units
Investigate electric power consumption rate for an item of equipment, an area of a plant or a complete facility. Get data beyond the 30-minute demand time frame that most utilities use to obtain average power usage by setting the demand time to units of seconds or minutes.
Power quality is an important and often overlooked element in reducing energy costs. If the power factor is not taken into account, an energy efficiency program could accidentally implement steps that increase the utility bill instead of lowering it. For example, replacing 100-watt incandescent bulbs with low-watt fluorescent bulbs saves energy but can worsen the power factor, possibly resulting in low power factor fines from the electric utility.
The CW240 also provides a demand feature that can be used to measure peak power usage over a specified time period. This data can be used to minimize peak power usage, or to shift peak usage to a more favorable time in accordance with electric utility time-of-day pricing.
Demand Time Setting:
Obtain detailed date to ensure a smooth power supply for operations, and prolong the life of equipment by reducing the effects of harmonics.
Inverter power supplies can cause distortions in voltages and currents, resulting in malfunctions, equipment damage and power loss. Therefore, it is critical to understand and monitor harmonics to ensure a reliable power supply. The CW240 provides displays of harmonics from the 1st to 50th for analysis to prevent problems.
Data Collection Time
View in-depth information on waveforms through easy-to-understand graphs.
Waveform measurement provides multiple ways to measure and analyze waveforms to see large waveform distortions that can indicate a potential problem in the system.
Data Saving Format:
Voltage Fluctuation Management
Protect equipment from harmful power fluctuations by understanding exactly when and where these flucutuations occur.
The CW240 detects dates/times of when fluctuations occur as well as the type of fluctuation, the channels where they occur, rms values and the periods between start and end. Once the voltage threshold is set, the fluctuations exceeding the threshold are detected.
