5.7.1 Ultrasonic classification

The Ultrasonic display on the UltraTEV Plus² includes the output of EA Technology's
proprietary ultrasonic classification algorithm. The algorithm processes measured
ultrasonic data in real time to give an indication whether the input data is a background
noise source or partial discharge activity.
The algorithm processes the data from the ultrasonic Microphone along with the phase
reference signal, and looks for patterns within the data stream which experts at EA
Technology have identified as typical indicators of partial discharge.
