Analysers capture extended transients

Electrical Review Logo

Outram Research  has announced a new revision of firmware for their PM7000 power quality analyser, Waveform Capture Extension, which allows capture of long-duration transients and waveform events. The new feature is designed to help engineers troubleshoot long-duration problems and to see the consequential impact of disturbances.

Whilst most transients and waveform events are over in less than three or four cycles, occasionally it is useful to capture longer periods. Examples include monitoring the network’s recovery from sag after reclosures, or to view the reaction of downstream control systems such as wind turbine control.

The Waveform Capture Extension allows for selective extension of the capture window beyond the 160ms that was previously possible, enabling recording for up to 60 seconds. Extensions of the different capture triggers can be set individually, enabling complete control over the monitoring of the disturbances that are recorded for the longer period.
