WT1800 Datasheet Accessory Kit
This new addition to Yokogawa's highly recognized digital power analyzer product line offers innovative measurement functions which benefit the engineer with electrical power measurements. It is the ideal measurement solution for testing Product Efficiency, and the design of Inverters, Motor Drives, Lighting Systems, Uninterruptible Power Supplies, Aircraft Power Systems, Transformer Testing and other power conversion devices. The High-end WT1800 is the successor to the WT1600 and designed for a wide range of applications, from energy-saving to large load applications. The Yokogawa WT1800 has a six element input capability to provide maximum flexibility, and Basic Power Accuracy of 0.1% with 5 MHz Bandwidth.

Yokogawa's previous model provides two different measurement modes, called Normal and Harmonic, and each of the measurements is performed separately. The WT1800 makes it possible to simultaneously measure voltage, current fundamental wave, harmonic components, and harmonic distortion factor (THD) in the Harmonic measurement mode, along with the conventional voltage and current RMS values in the Normal measurement mode. You do not need to switch modes and can measure all data at high speed. In addition, up to the 500th order harmonic can be measured for fundamental frequencies.
