MONTESTO 200

Portable on-line partial discharge measurement and monitoring system

Convenient 2-in-1 solution

MONTESTO 200 is a portable, two-in-one solution that enables you to perform both on-line partial discharge (PD) measurements and temporary on-line PD monitoring: It can be used on various medium-voltage and high-voltage electrical assets under load to assess insulation condition. You can use the IP65 rated MONTESTO 200 both indoors and outdoors. Automated software features enable users to quickly and reliably identify and locate signal sources.

MONTESTO 200 at a glance

Plug-and-play setup
The on-line PD measurement and monitoring device can be easily connected via a terminal box to permanently-installed partial discharge sensors. This enables quick and safe plug-and-play connections during setup without having to shut down the asset.
User-friendly analysis
Automatic software features, such as 3PARD (3-Phase Amplitude Relation Diagram) and Automatic Cluster Separation, separate noise from PD signals to help you easily and reliably determine the signal source.
Remote data access
A built-in computer enables long-term data collection and archival. You can remotely access the computer and collected data with the web interface. You can also set up the system to send email alarm notifications when PD levels exceed user-defined thresholds.

Reliable indicator of insulation condition

Partial discharge (PD) activity is a reliable indicator of insulation condition, and it is often a sign of insulation defects that can cause failure in electrical assets. On-line PD measurement evaluates PD activity and offers a snapshot of insulation condition status when the asset is in operation. Temporary on-line PD monitoring indicates changes in PD activity over specified periods of time during an asset's service life.

“OUR MONTESTO 200 combines two functions into one portable solution. It enables users to easily and safely perform both on-line partial discharge measurements and temporary on-line partial discharge monitoring on various medium and high voltage assets under load.”
