CW240 Clamp-On Power Analyzer
Brand: Yokogawa Electric CorporationThe 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.
Features- The CW240 offers many unique features to improve energy efficiency through highly detailed data collection and easy-to-understand displays.
- Measurement of Instantaneous Values: Unique 3-wattmeter display provides an immediate value for each measurement element (voltage/current/electric power, etc.) to allow users to cut energy costs through a better understanding of power consumption, maximum load factor and peak current.
- Power Quality Measurement: Measures and displays active power, regenerative power and reactive power quality—along with simultaneous displays of each value.
- Demand Management: Enables users to set the desired demand limit in preferred time units in order to determine the maximum power demand.
- Harmonics Measurement: Reveals distortions in voltages and currents that can cause malfunctions and power loss. Measures harmonics from the 1st to 50th. User-friendly data display in list, bar graph (linear/log) or vector (inflow/outflow judgment).
- Waveform Measurement: Displays voltage and/or current of each phase in easy to understand graphs.
- Voltage Fluctuation Measurement: Detects time and date of each fluctuation occurrence, the fluctuation type, the rms values, and the start and end period.
