便携式钳式功率计

能效问题已受到全球范围内的普遍重视，需要有合适的产品来监视每个工厂的能量要求。CW240和CW120功率监视器系列允许客户使用便携式记录装置来测量电压、电流、功率、Var、VA、PF、PA、频率、谐波和需量。1P2W到3P4W功率监视器提供当前电力状况的可视化报告，以防止发生重大能耗问题或电费超支。

CW10与其说是记录仪，不如说是一款测试仪，可以测量单相AC和DC功率、电压、电流、功率因数、频率、谐波。该产品是用电设备维护人员的得力助手，也适用于太阳能和风力发电等可再生能源的设备。

电能质量分析仪 CW500

The Yokogawa CW500 is a portable power meter that utilizes current clamp-on probes, navigation screens and quick start guides to enable user friendly power consumption and power quality measurements in the field that conform to IEC6100-4-30 Class S.

Power Measuring and Logging

• Simultaneously measures 3 CH Voltage input, 4 CH current clamp probe input, 2 CH DCV input.
• Instantaneous/Average/Maximum/Minimum value list or trend graph screen of Voltage/ Current/Power/Power factor/Phase Angle/Phase Advanced Capacitance Calculation.
• Integration Value of Active/ Reactive/Apparent Energy are each displayed for consumption and generation.
• Demand monitoring which displays screens of present power consumption compared to aimed demand power values.

User Support

Quick Start Guide Function:

• The Quick Start Guide Function supports correct wiring and setting before measuring.
• The Quick Start Guide Function automatically recognizes the type of current clamp probe.

Vector Display:

• The Vector Display indicates Voltage and Current phase difference and values between input channels of voltage and current.
• The Vector Display checks whether the wiring is correct or not.

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 ?s 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

Measure Continuous Malfunction of the Power Line

Harmonics

• Measure and display graphs and lists of up to the 50th Harmonic components of voltage, current, and power for each phase and total.

Flicker

• Measures 1-minute flicker (Pst, 1 min), short flicker, (Pst) and long flicker (Plt).

Unbalance rate

• Displays voltage and current unbalance rate on 3 phase wiring.

CW500Viewer (Included PC software)

• Automatically display the graphical and report data by clicking on the file on the PC display.
• Manage multiple settings of the unit.
• Measure in real-time using USB communication.

Types of data
