Precision power analyser measures to suit
Designed to measure power any way the user wants, the WT1800E power analyser has been announced by Yokogawa. According to the company, it introduces new standards of accuracy and flexibility in power measurement.
It was developed to be flexible enough to provide engineers with accurate and reliable power measurements for demanding applications, such as the manufacture of energy efficient devices and appliances, plug-in hybrid/EVs, lighting, aircraft and for renewable energy technologies. It can also be used for the input and output of motors, inverters, actuators, energy recovery systems and generators.
There are six channels to accommodate three-phase systems and other applications requiring multiple input channels.
Modern energy saving circuits employ high frequency switching techniques which challenge the accuracy of power analysers, says the company, but this instrument has been designed to retain accuracy at and beyond these frequencies.
It offers guaranteed power accuracy of 0.05 per cent of reading plus 0.05 per cent of range. It is also capable of harmonics analysis up to the 500th order of a 50/60Hz fundamental frequency. Accuracy can be improved with calibration at the company’s ISO 17025 accredited lab.
