Yokogawa WT1800 Overview
The perspective of the efficient use of energy is boosting demand for inverters to convert 50 Hz or 60 Hz AC power to DC power, grid connection controllers to control reverse power flow occuring due to excess power, and battery chargers/dischargers.
The WT1805 is capable of simultaneously measuring the harmonic distortion of the input and output current of these devices. Challenging the common wisdom that “harmonic measurement is limited to a single line,” the WT1805 is capable of performing two-line simultaneous harmonic measurements. The WT1805 is also capable of measuring up to the 500th order harmonic even at high fundamental frequencies such as a 400 Hz frequency.
The Yokogawa WT1805 High Performance Power Analyzer has broken the mold and is capable of reading user-created image files (BMP) as display screens to allow viewing data in a flexible format. Thus the display screen can be customized in a more user-friendly and easy-to-read manner.
