MONTESTO 200 – Portable on-line partial discharge measurement and monitoring system

Germany, Berlin: OMICRON’s MONTESTO 200 combines on-line partial discharge (PD) measurement and temporary on-line PD monitoring functions into one portable system.

The IP65 rated MONTESTO 200 can be used both indoors and outdoors for insulation condition assessments on various medium-voltage and high-voltage electrical assets under load, including motors and generators, power transformers and power cables. Partial discharge activity is a reliable indicator of insulation condition, as it is often a sign of insulation defects that can potentially cause failure in electrical assets.

The lightweight and compact MONTESTO 200 comes with all the necessary connection cables in a wheeled case that is easy to transport to various locations for on-line PD measurements on site. The system’s wide measurement frequency range can be freely adjusted to ensure an optimal signal-to-noise ratio. PD measurement data streams can be recorded and replayed later for detailed analysis.

MONTESTO 200 features a built-in computer that enables long-term data collection and archival. Users can access this computer from any remote location to set up monitoring sessions and to view the collected PD data with the system’s convenient web interface. Users can also configure the system to automatically send email alarm notifications when PD levels exceed user-defined thresholds.

Unique software features, such as 3PARD (3-Phase Amplitude Relation Diagram) and Automatic Cluster Separation, automatically separate noise from PD signals to help users quickly and reliably determine the signal source. Data from third-party sensors can also be easily integrated for correlation with the PD data.

MONTESTO 200 is intended for use by asset manufacturers, maintenance teams at utilities and industrial sites, as well as service providers for convenient on-line PD measurements and temporary PD monitoring.
