transient measurements

Ultrasonic flowmeters that use transit-time ultrasonic transducers face measurement errors due to ``crosstalk,'' whereby the working signal travels through the pipe wall and couplings, interfering with the signal from the fluid.  Although various procedures have been proposed to solve the issue of crosstalk, they're limited to low-frequency ranges, or they are not effective in high-pressure environments.

Design information of a real 50 MVA power transformer is available in this dataport. In addition, transient measurements of 4 different configurations are included.

This material has been shared with the authorization of Prof. Alvaro Portillo (Task force leader of JWG A2/C4.52) and the WEG transformer factory. 

We express our deepest gratitude to Prof. Alvaro Portillo and WEG for allowing the use of this information for academic and research purposes.
