Power Diagnostix ICMcompact Partial Discharge

ICM Compact

Power Diagnostix 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 Power Diagnostix software to capture screenshots or to implement remote control of the unit.

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 switch gear and others. A wide range of accessories adapts the ICMcompact to specific testing applications and noise conditions.

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 ICMcompact offers convenient on-site testing of equipment such as cable accessories or sensors installed with gas insulated switch gear, for instance.

Generally, this unit can be used with the full range of the ICMseries preamplifiers, covering the IEC60270 standard frequencies.

To adapt the basic ICMcompact unit to suit special measurement requirements, it can be equipped with various options:

  • Voltage measurement. Adds the HVM oscilloscopic display showing the wave form of the high voltage and calculates Û, Û/√2, Urms, etc.
  • Cable PD location. An additional DSO board samples the PD signal at 100 Msample.
  • Analog gating to cancel external disturbance. This option offers sensitive measurements even in noisy environments.
  • MUX4. Four-channel multiplexer for testing three-phase equipment, such as power transformers. For each channel the unit maintains an individual setup and calibration.
  • MUX12. This option offers a built-in 12-channel multiplexer or a remote 12-channel switching box for acceptance testing on large power transformers.
  • AUX4. For long-term testing up to four additional parameters can be captured as 0(4)-20 mA or 0-10 V signals.
  • RIV measurement. Adds a radio influence voltage measurement function to the instrument (needs the SPEC option and includes the MUX4 option).
  • Modem. Allows communication with the instrument via analog telephone line.
