Yokogawa CW240 Clamp on Power Quality Meter
The Yokogawa CW240 supports four single-phase two-wire systems, two single-phase three-wire systems and even SCOTT connections. The Yokogawa CW240 supports currents ranging from 200.0 mA to 3000 A and voltages up to 1000 V. Electric power (instantaneous values, electric energy, and demand), harmonics, voltage fluctuations (dip, swell, and instantaneous power failure) and waveform scan all be measured simultaneously.

- Backup Power supply attachments available
|Measurement of Instantaneous Values: The Yokogawa CW240 can be used to carry out investigation regarding renewal of electric equipment such as transformers in building, check load factors and demand factors, and to check current/voltage fluctuation at motor start-up.
Power Quantity Measurement: The Yokogawa CW240 can measure and display the power quantity consumed up to the specified time (from the start of integration until the end).
|Demand Measurement: Measurement elements:
Demand time limit: Length of time set to obtain the average power (normally 30 minutes) Demand power: Average power during the demand time limit
Voltage Fluctuation Measurement: The CW240 detects dates/times of when fluctuations occur, fluctuation type, channels where they occur, rms values, and periods between start and end. The voltage threshold is set, and fluctuations exceeding the threshold are detected.
|Measures Loads in Four Systems Simultaneously: The Yokogawa CW240 enables simultaneous measurement of loads in four systems in the case of the single-phase 2-wire system, and in two systems in the case of the single/three-phase 3-wire system (common to voltage). Current clamp probe/range can be set for each system.Reduces Operations Errors at Work Site:
Saving Large Amounts of Data: Use of an external memory card (compact flash) makes it possible to save a large amount of data. A memory card (*1) of up to 512 MB can be used, and the data is saved in CSV format. (*2)In addition, the Yokogawa CW240 has a 1MB internal memory. *1: Memory cards purchased from Yokogawa should be used. *2: Data shorter than one second is saved in binary format. Screen copies can be made in bitmap format. Voltage fluctuation data is saved in text format.
