The ICMmonitor Portable partial discharge (PD) monitoring system from Power Diagnostix ’s ICMmonitor Portable is a compact non-invasive PD monitor for continuous on-line evaluation of the insulation condition of medium and high voltage (MV and HV) assets.

The ICMmonitor Portable comprises a spectrum analyser, an acoustic detector, and a conventional PD monitor in one instrument. This combination enables PD measurements, even with high levels of background noise, on assets such as power transformers within substations or power plants.  

Its built-in multiplexer allows you to scan three-phase systems or multiple sensors, and its simple push-button interface and on-screen menus, located in an embedded LCD panel, make it incredibly easy to use.

The display modes include, a horizontal bar graph display, monochrome phase-resolved PD patterns for classification of defects, a scope-like display showing phase-summed charge pulses superimposed with the applied voltage wave, and a spectrum display showing the frequency spectrum of the acquired signals.


Power Diagnostix’s ICMmonitor Portable is an autonomous instrument that, can be used as stand-alone monitoring device. It is equipped with a serial computer interface for the download of trending data and remote access, e.g., by LAN network (TCP/IP) or USB. Special software allows the remote control of the instrument, data evaluation, and in-depth diagnosis of the acquired data. This service software also provides easy access to view, compare, and analyse the stored data. 

The instrument is used principally for temporary
on-line monitoring and spot testing of:

  • Power transformers

  • Motors

  • Generators

  • Cable systems

FAQs

  • High voltage assets, such as power transformer, cable systems, and generators, are of high importance for every grid. With high electric fields in comparatively small spaces, failure can lead to extensive damage and long outages. Temporary PD monitoring with the ICMmonitor Portable can help to keep these units in service for longer by the early identification of insulation defects and efficient planning of maintenance or repair work. Thus, PD monitoring can prevent costly asset breakdowns and system failures. 

  • It is always useful to gather as much information as possible in advance. In particular, try to be informed about:

    • The type of asset to be monitored.

    • The technical details of the asset (nameplate, specification, age).

    • The types of sensors or the types of coupling units.

    • The test conditions: On-line or off-line?

    • The environmental monitoring conditions.

    • The reason for monitoring.

    • The results of previous measurements and maintenance, SAT/FAT.

    • Applicable or relevant standards, guidelines, and technical brochures.

  • Observing the frequency spectrum of a harshly disturbed partial discharge signal allows you to select frequency bands with fewer disturbances. Using such a selected frequency for a partial discharge acquisition, gives a largely improved signal-to-noise ratio, resulting in a clear pattern acquisition. The combination of spectrum analyzer and PD detector within one instrument opens a broad field of new possibilities when analyzing isolation defects even in noisy environments.

  • Power Diagnostix offers a broad range of PD coupling units, cables, and other accessories to cover most of the possible monitoring situations with the ICMmonitor Portable. Please refer to Power Diagnostix’s accessories catalogue for further information.
