Description
The ICMmonitor on-line partial discharge monitor continuously monitors the condition of the insulation system of your medium and high voltage (MV and HV) assets and gives you the ability to analyse the acquired data. The in-depth analysis of the trending information delivered by the ICMmonitor enables you to detect defects in an early state and prevent costly failures.
The ICMmonitor combines three devices into one instrument: A spectrum analyser, an acoustic detector, and a partial discharge (PD) monitor. The combination of spectrum analyser and PD detector greatly expands the measurement possibilities when analysing the insulation systems in a noisy environment. Thus, the ICMmonitor offers continuous PD on-line monitoring and excellent measurement results, even with a large amount of electrical noise.
With the monitoring web server function (MWS) you can remotely access the ICMmonitor instrument and see topical information on your asset’s condition. Additionally, you can receive an email notification in the case of system errors.
The ICMmonitor can be used for monitoring the following assets:
Power transformers
Motors
Generators
Cable systems
Standard features of the ICMmonitor are:
PD spectrum analysis for the selection of frequency bands with less disturbances, resulting in an improved signal-to-noise ratio.
A built-in four-channel multiplexer offers scanning of three-phase systems or multiple sensors, with each measurement channel separately configurable.
Effective noise gating for blocking phase-stable or phase-independent noises
Automatic data acquisition and storing for trend analysis, alarming, and reporting
UHF measurements
The instrument is available with a wide range of optional features, giving it flexible installation and a range of configuration options that can meet your specific need.
Available features are:
Industrial monitoring cabinet with necessary supply and safety components pre-installed, suitable for outdoor installation
Specialised control software for remote access and download of stored trending data.
Eight-channel multiplexer.
Monitoring web server for web browser based remote access and control from everywhere in your network.
Mobile communication interface for remote access via UMTS
Up to four additional output signals for external monitoring purposes.
Up to six additional inputs for sensor signals.
IEC 61850 interface.
Built-in preamplifier.
Pre-installed control PCs or notebooks.
Expert software for PD pattern classification according to their PD faults.
Power Diagnostix’s ICMmonitor 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 provides easy access to view, compare, and analyse the stored data.
Additionally, the optional monitoring web server (MWS) provides an Ethernet gateway for a platform-independent remote access to monitoring data recorded with the ICMmonitor. Alarms triggered by the instrument can be reported by automated email to the responsible person.
Combined with an LTE mobile router, a secure remote access via the Internet can be provided.

Frequently Asked Questions
Why is PD monitoring recommended for medium and high voltage assets?
Medium and 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. PD monitoring with the ICMmonitor can help to keep these units in service for longer by early identification of insulation defects and efficient planning of maintenance or repair work. Thus, PD monitoring can prevent costly asset breakdowns and system failures.
What does IEC 60270 compliance mean?
The IEC 60270 standard covers the measurement of partial discharges (PD) occurring in electrical equipment, components, or insulation systems when tested with AC voltages up to 400 Hz or with DC voltage. It specifies requirements for the measurement equipment and for calibrators that should be used for measuring. Additionally, it defines three possible measurement setups to ensure reproducible and comparable PD measurement results.Power Diagnostix’s ICMmonitor meets all the requirements of the standard and thus guarantees highly accurate and reliable measurement results.
What is the advantage of a spectrum analysis panel in connection with partial discharge measurements?
Observing the frequency spectrum of a harshly disturbed partial discharge signal allows 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 with large noise.
What kind of accessories are available for PD measurements with the ICMmonitor?
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. Please refer to Power Diagnostix’s accessories catalogue for further information.
