Description
The ICMcompact is Power Diagnostix’s standalone partial discharge detector. This digital instrument has been designed for the condition evaluation of medium and high voltage (MV and HV) insulation and is typically used for quality assurance and quality control, including factory acceptance tests (FAT), end-of-line testing, and post repair. It is also suitable for field use.
The ICMcompact is primarily intended for the following assets:
Factory acceptance tests for MV and HV assets
Distribution transformers
Instrument transformers (voltage transformers and current transformers)
MV and HV cables
Electronic components (e.g., insulated-gate bipolar transistors)
The ICMcompact has a simple push-button interface and on-screen menus located in an embedded LCD panel. The display modes include a simple PD charge meter with adjustable ‘needle’ sensitivity, monochrome phase-resolved PD patterns for classification of defects, and a scope-like display showing phase-summed charge pulses superimposed with the applied voltage wave.
The ICMcompact is an autonomous unit, but it can be connected to a computer with installed Power Diagnostix software to capture screenshots or to implement remote control of the unit.
To adapt the ICMcompact to your specific needs, it can be equipped with numerous extras and additional functions:
Partial discharge spectrum analysis
Partial discharge fault location for cables with digital storage oscilloscope (DSO) function
Radio influence voltage (RIV) measurement
High voltage measurement (HVM)
Analogue gating
Four- or twelve-channel multiplexer
Battery-operated and cordless device with up to three hours operation time (Explorer case only)
LAN and fibre optic serial link
Auxiliary inputs for recording additional data such as power and temperature
Computer-controlled software
Rugged case ICMoutlander for outdoor use
For greater configuration flexibility, we have created the ICMcompact pro. This unit has a colour touch display and offers a wider range of accessories and additional functions. It also comes available in three housing versions:
Half 19-inch desktop version
19-inch rack mountable version
Robust outdoor Explorer case

Frequently Asked Questions
What does IEC 60270 compliance mean?
The IEC 60270 standard covers the measurement of partial discharges 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 ICMcompact 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 analyser and PD detector within one instrument opens a broad field of new possibilities when analysing isolation defects even with large noise.
Is it necessary to rearrange the test setup every time I change the test object while performing a partial discharge routine test?
An optional built-in multiplexer allows you to switch between several measuring channels for different test objects without the need to rearrange the test setup for each new test object. Power Diagnostix offers four- or twelve-channel multiplexers to speed up partial discharge routine tests by avoiding time-consuming setup modifications foür every test object.
