Options expand precision power analyser
A number of new features are now available to boost the measurement and communications functions of the Yokogawa WT3000 precision power analyser.
This calibration is traceable to international standards by the accredited NMI (Nederlands Meetinstituut) in Delft and the JEMIC Institute in Japan.
"The calibration of AC electrical power has always been a challenge", said Terry Marrinan, Yokogawa's European Sales and Marketing Director.
"The calibration of AC power is different from calibrating just voltage and current and only a few calibration laboratories worldwide are actually able to carry out AC power calibration".
The calibration frequency range for AC power is often limited to between 50 and 440Hz.
Modern power meters are, however, used for measurements on switch-mode power supplies, high-frequency electronic lighting ballasts, soft starters in motor control systems and frequency convertors in traction applications.
The Yokogawa WT3000 wide bandwidth power analyser has revealed the gap in available national standards between the two calibration frequencies of 50Hz and 1MHz.
