Partial discharge monitoring systems

Partial discharge measurements are used to validate the integrity of the insulation system at the end of the production line or when commissioning gas insulated switchgear and lines (AIS/GIS/GIL).  On-line partial discharge measurements utilizing acoustic as well as UHF sensors help keeping such equipment in service. External ring antennas, window sensors, or embedded sensors allow survey type measurements and monitoring of the partial discharge activity in the UHF range.  Adiradh Energy offering  range of instruments cover the entire needs of partial discharge testing on gas-insulated substation equipment from production testing and commissioning to maintenance and monitoring. The ICMcompact is the most popular device used in test benches of switchgear manufacturers, the ICMsystem, the AIAcompact and the ATTanalyzer are choosen for onsite inspection and maintenance work, and the GISmonitor for permanent online monitoring in substations.

Partial discharge monitoring on GIS systems Portable 

Adiradh Energy offers GISmonitor which is a portable unit for partial discharge measurements on gas-insulated switchgear (GIS) caused by hopping particles, floating potentials, cracks in insulators or spacers, or other degradation in the insulation system.  GIS monitor offers parallel real time PD acquisition on up to 40 channels. PD measurements can be easily applied on GIS systems without the need of interrupting the operation. Such temporary online monitoring helps to identify internal imperfections of the insulation system, which may lead to breakdown and system failure in the future.

PD monitoring on Gas-insulated switchgear GIS systems

GISmonitor Portable

Due to the dielectric properties of the SF6 gas, partial discharge activity in gas insulated switchgear covers a bandwidth of well beyond 2 GHz. The mechanical properties of the components of gas insulated switchgear further allow transmission of such signals over a distance of a couple of meters. Thus, the partial discharge monitoring of GIS equipment is done preferably in the UHF range.

On line Partial discharge monitoring on GIS systems 

Adiradh Energy offering GISmonitor which  is a scalable monitoring device for continuous monitoring of gas-insulated switchgear (GIS) using true prarallel, real-time acquisition techniques.Each 8-channel acquisition plug-in board operates fully stand alone,
but can be com-bined with a virtually unlimited number of units, to monitor all PD sensors in one GIS PD monitoring system in parallel. A partial discharge monitoring acquisition rack (PDMAR) carries up to 15 plug-in boards – each with eight channels – providing up to 120 channels.An industrial type PC installed in a partial discharge monitoring control rack (PDMCR) reads all data of the instruments via the high speed fiber optic LAN ring
providing communication redundancy. The GISmonitor indicates with on-board LED’s internal states and alarm conditions. Cabinets are used to accommodate all instruments and the industrial type PC. Each cabinet comes with a standard 19” frame, an uninterruptible power supply, a network switch as well as temperature controlled cooling and heating. Cabinets for indoor applications feature a protection class of IP54, while cabinets for outdoor applications reach a protection class of IP65.

PD monitoring

PD monitoring acquisition and control racks

The GISmonitor is designed to suit all currently available UHF sensors for GIS PD monitoring. This includes embedded and external retrofit UHF sensors. A special input protection unit (IPU2) blocks strong transients (VFT). The preprocessing unit FCU2 demodulates UHF signals into a lower frequency band. The user interface software panel of the GISmonitor monitoring system is installed on the local industrial PC and can be installed additionally on any remote computer for data evaluation and diagnosis. Using an administrative setup allows configuring the system and the embedded service program.

Continuous on-line monitoring of partial discharge activity in high voltage equipment

Adiradh Energy offers  Partial discharge detector Model ICMmonitor  which is an instrument for continuous on-line monitoring of partial discharge activity in high voltage equipment. The instrument tracks changes in key discharge quantities for storage in trending diagrams and for triggering user-settable alarms. TCP/IP, Modem, fiber optic or direct serial links enable remote access and full remote control. The latest version of the ICMmonitor comes with spectrum analysis function,acoustic signal detection, and a conventional partial discharge measurement circuit. A built-in four- or eight-channel multiplexer offers scanning of three-phase systems or multiple sensors. It is used principally for permanent, continuous on-line monitoring of rotating machines, cable systems, power transformers, and gas-insulated switch gear (GIS).

ICMmonitor is an instrument for continous on-line monitoring of partial discharge activity in high voltage equipment. The instrument tracks changes in key discharge quantities for storage in trending diagrams and for triggering user-settable alarms.

 

ICMmonitor

ICMmonitor, with its embedded display

ICMmonitor, with its embedded display multifunctional, convenient trending, and settable alarms, is an ideal solution for continuous on-line monitoring of rotating machines and other electric devices in industrial and utility applications.

PD Detector

ICMmonitorr with spectrum analyzer

Combining a spectrum analyzer, an acoustic detector, and a conventional partial discharge monitor in one instrument the ICMmonitor enables PD measurements even with a large background noise e. g. on power transformers within substations or power plants.

Power Diagnostix ICMmonitor is a digital PD detector for permanent installation and continuous monitoring of medium and high-voltage insulation. ICMmonitor software automatically maintains the trending information as well as the phase-resolved pattern of a multitude of ICMmonitor units. The instrument can be connected to a computer via serial interface, modem, or TCP/IP. A special software allows  the remote control of the instrument and the download of the stored data. An autoscan function takes the trending information as well as the phase-resolved pattern of one or multiple units.
