Yokogawa WT3000 (760303) Precision Power Analyzer with Power Meter Options: 03/SV/M/B5/C12
In recent years, the demand for energy-efficient machinery and equipment designed to address global environmental problems and to effectively utilize energy resources has been increasing. In Japan, the Law Concerning Rational Use of Energy was revised in response to the Conference of Parties III (COP3) conference on global warming, which was hosted by Kyoto in December 1997. The Japanese Government ratified the Kyoto Protocol in June 2002. Internationally, the Energy Star Program was launched in 1995. The energy efficiency standard of this program applies to home appliances and OA equipment. Now that hybrid automobiles, inverter-driven refrigerators and air conditioners are widespread, greater accuracy is needed in power measurement.
The recently developed WT3000 meets the demands of the high-accuracy power measurement market by offering the world's highest accuracy for power measurement.
FEATURES
High-accuracy and Broad Bandwidth
The basic accuracy, or the accuracy of measurements at commercial frequencies of 50/60 Hz, is ± (0.02% of reading and + 0.04% of range). The frequency bandwidth covers 0.1 Hz to 1 MHz as well as DC signals. The basic accuracy and the measurement bandwidth of the WT3000 are much greater than those of its predecessor, the WT2000

.
With these improved features, the WT3000 serves various applications for high-accuracy power measurement.
Maximum of Four Input Elements
Since the WT3000 can be equipped with a maximum of four input elements, one WT3000 unit can measure the inputs and outputs of a three-phase inverter. With two units, multi- channel power measurement can be performed on a synchronized basis.
Common-mode Voltage: 1000 V
The WT3000's predecessor employed a photocoupler to insulate the input circuit, and its rated common-mode voltage was 600 V. The WT3000 employs a newly developed pulse transformer for input circuit insulation. By maintaining a sufficient insulation distance, a common-mode voltage of 1000 V was achieved. This enables measurement of ever- increasing inverter drive voltage.
High-speed Data Updating
The maximum data updating period of the WT3000 is 50 ms, which is five times the speed of its predecessor. This feature is useful in evaluating the characteristics of the motor (torque, rotation speed, and the like). It is also effective in measuring phenomena that tend to change in a relatively short period of time such as ramp current and the secondary voltage of lighting that changes at high frequencies.
Motor Evaluation (optional)
The analog or pulse output of the torque and the rotation speed can be input directly from the torque meter to the WT3000. Torque and rotation speed readings as well as motor output, synchronous speed, sliding, motor input/output efficiency, and inverter input/motor output efficiency are calculated to measure the total efficiency of the inverter and the motor. Just one WT3000 unit can perform comprehensive measurements such as these.
