AC calibration service covers wide bandwidth

The Yokogawa Europe calibration service offers power calibration at DC and AC from 0.1Hz to 100kHz.

Yokogawa Europe is offering a new calibration service for high-frequency AC power measurement through its Calibration Centre in Amersfoort, the Netherlands.

Based on Yokogawa's WT3000 precision power analyser, the Yokogawa Europe calibration service offers power calibration at DC and AC from 0.1Hz to 100kHz.

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.
