Precision power analyser offers 0.05% accuracy, extended harmonics
Increased flexibility comes with the WT1800E’s six channels which means it can accommodate three-phase systems and other applications requiring multiple input channels. Energy saving circuits employ high frequency switching techniques which challenge the accuracy of power analysers. The WT1800E has been designed to retain its outstanding accuracy at and beyond these frequencies, analysing multiphase inputs during motor and drive design or meeting the efficiency standards of photovoltaic inverters.
Key features of the WT1800E include:
– Accuracy; guaranteed power accuracy of 0.05% of reading plus 0.05% of range
Capable of harmonics analysis up to the 500th order of a 50/60 Hz fundamental frequency
Accuracy can be further improved with calibration at Yokogawa’s ISO 17025 accredited lab.
– Reliability; high levels of stability mean that measurements are consistent when repeated over the lifetime of the instrument.
– Flexibility; up to 6 input channels, with a wide range of display and analysis features

PC connectivity.

Terry Marrinan, VP of sales and marketing at Yokogawa Europe BV, comments, “[Engineers] are increasingly having to ask themselves ‘How accurate are my power measurements?..We guarantee the power accuracies of our analysers over their full ranges and specify the effects of all the other factors such as power factor, crest factor, phase angle error, temperature range, warm-up time, stability period and common mode rejection.”
