The ICMcompact is part of the ICMseries of digital partial discharge detectors. The ICMcompact is a compact, stand-alone instrument for evaluating the condition of medium and high voltage insulation. It is often used in quality assurance and quality control tests in manufacturing. Stand-Alone Instrument Partial discharge (PD) measurements are a proven method for effective, nondestructive evaluation of electrical insulation. The ICMcompact provides a simple push-button interface and on-screen menus in an embedded LCD panel. The LCD display modes include a simple PD charge meter with adjustable “needle” sensitivity, monochrome phase-resolved PD patterns for characterization of defects, and a scope-like display showing phase-summed charge pulses superimposed with the applied voltage wave. Although the ICMcompact is an autonomous unit, it can be connected to a computer installed with software to capture screenshots or to implement remote control of the unit. The ICMcompact equipped with an optional DSO board can be used to locate partial discharge defects in power cable. Using time domain reflectometry, in which the PD and its “echoes” travel the length of the cable under test, the ICMcompact provides the proportional distance of the PD fault along the cable. The instrument can be optionally equipped with a 12bit A/D converter for voltage measurement. This feature allows to record pd and voltage values by software, i.e. for acceptance testing or quality tests. Standard Display Modes In standard configuration the ICMcompact comes with four main display modes. The scope display shows the maximum peak values of discharges vs. phase. The refresh Applications Instantly displaying information in an intuitive interface, the ICMcompact is a good choice for applications such as quality control tests in manufacture of electrical products, and for quality assurance of industrial and utility equipment from capacitors and bushings to gas-insulated switchgear and others. A wide range of accessories adapts the ICMcompact to specific testing applications and noise conditions. rate is about 5 pictures per second which gives a good view of increasing or decreasing ENERGY SUPPORT Experts in providing mobile Solutions www.energy-sup

ENERGY SUPPORT pd activity. The pd pulses can also be put on top of the drawn sine wave as shown above. To get a phase resolved pattern a hold function is available. Each pd pulse is plotted related to its amplitude and phase position. Optional Features and Displays a) Gating This optional function for noise cancellation requires an additional input with logarithmic pre-amplifier (RPA6). The firmware is extended by a new sub-menu to adjust the gating parameters. b) DSO board extension This option allows sampling pd pulses and its reflections running over HV cables for cable fault location....

Available Software The instrument can be connected to a PC or laptop by serial interface. The upper picture shows the standard software to read out the display contents and to record data like pd peak values or voltage. The next picture shows the advanced software ICMcompro for cable fault location. To integrate the I CM compact into a full test environment it is possible to use the HVpilot software. This software reads out data from different instruments and runs high voltage Steptests automatically. Technical Data: Mains Supply: Line Fuse: Power Requirements: Display: Display...
