Power Analyzer/Power Meter: Why Doesn't the Power, Power Factor, and Phase Angle of Each Input Element Match When Measuring Balanced a Three-Phase Load?

With 0.02% accuracy and 1MHz bandwidth, the WT3000 delivers where the highest precision measurements are required. It is the industry standard for R&D work on inverters, motor drives, lighting systems and electronic ballasts, UPS systems, aircraft power, transformer testing, and other power conversion devices.

The WT1800 High Performance Power Analyzer from Yokogawa Test&Measurement offers maximum flexibility with up to six wattmeter elements, high bandwidths, simultaneous high speed digitizing, and wide voltage and current ranges. Although this model is still available, the newer WT1800E offers higher accuracy.

The WT2000 digital powermeter series has been designed with emphasis on basic performance (bandwidth, accuracy, response speed, and noise immunity) from the viewpoint of measurement of electrical quantities. The broad range of functions of these power analyzers enable them to be used in various fields of applications.

• Power and Harmonic (THD) Measurements with Independent Range Controls
• Efficiency measurements of AC/DC or DC/AC Inverters & Motors

Measure characteristics of devices that generate, transform or consume electricity. Also called power meters or wattmeters, these devices measure parameters such as true power (watts), power factor, harmonics, and efficiency.
