Tokyo, Japan - February 15, 2011
Yokogawa Meters & Instruments Corporation announces the market release on this date of a new power measuring instrument, the WT1800 precision power analyzer.
As the top supplier of power meters in Japan and all other markets*1, Yokogawa Meters & Instruments actively supports energy-saving efforts by offering customers a variety of products that enhance the measurement of power consumption and improve efficiency in the development and evaluation processes.
The WT1800 is the successor to the well reputed WT1600 digital power meter. In line with intensifying energy-saving efforts, the WT1800 offers a number of enhanced functions that improve the accuracy of power measurement. This high-performance power meter is also capable of simultaneously measuring harmonics on an inverter's input and output sides, an industry first.
WT1800 Precision Power Analyzer
To curb global warming, greater efforts are being made to use power more efficiently. This is driving the growth of the photovoltaic, wind power, and other renewable energy markets, and is leading to accelerated development of environmentally friendly electric vehicles (EV), plug-in hybrid vehicles (PHV), and energy-efficient home appliances with energy-saving functions. The development of such products requires very accurate measurement of power consumption to determine their energy efficiency. For example, conversion efficiency must be improved to reduce power loss in inverters, which play a key role in enhancing the energy efficiency of home appliances and industrial equipment. To accomplish this, superior power meters that are accurate to within ±0.3% must be used.
As this requirement was beyond the capabilities of our existing models, we have developed the WT1800, focusing on improving basic performance aspects. With its increased measurement accuracy, the WT1800 will assist in the development of energy-saving products.

*1 Based on our survey
*2 A harmonic is a component frequency of a signal that is an integer multiple of its fundamental frequency. Harmonics are created during power conversion, and their transmission through electric circuits to other electrical devices can cause malfunctions and overheating.
