The ICMmonitor is part of the ICMseries of digital partial discharge detectors. It is primarily used for continuous on-line monitoring of rotating machines, GIS (gas-insulated switchgear) transformers, and critical underground cables. Detecting insulation problems before they cause breakdowns can prevent expensive unplanned outages.
A partial discharge (PD) is an electrical discharge within electrical insulation that does not completely bridge the gap between electrodes. This detector is a stand-alone instrument, configured and operated through on-screen menus and corresponding push buttons. It measures key partial discharge quantities, maintains trending information over a chosen time period, and offers a monochrome phase-resolved PD pattern display. Although it does not need to be connected to a PC to operate, it can be connected to a PC to download data and capture screenshots.
An important feature of this instrument is telemonitoring, which allows remote access to the detector through a modem from anywhere in the world. In the event of an alarm trigger, the manufacturer can dial into the monitoring system in order to download data, inspect the system and give instant advice. The device also provides effective noise gating that blocks phase-stable noise as well as noise independent of the applied voltage cycle, allowing the it to be used in noisy environments without losing PD data.
