Product description
When it comes to partial discharge (PD) monitoring, GISmonitor by Power Diagnostix is an ideal choice. The main task of GISmonitor is to provide users with a reliable partial discharge monitoring system capable of detecting defects hidden inside SF6 gas insulated switchgear (GIS), such as particle jumps, floating potentials, cracks in insulators, protrusions, or other damage in the insulation system.
The system hardware is optimized for continuous, parallel, real-time PD data collection to record every signal from pre-installed UHF sensors inside the GIS enclosure, ensuring no PD activity goes unnoticed.
Frequency converter units (FCU2) capture UHF signals from embedded UHF sensors and demodulate them to lower frequency ranges for easy long-distance transmission. Special input protection units (IPU2B), placed at the UHF sensor outputs, block strong signals such as very fast transient processes (VFT) and protect the PDMS.
Each UHF sensor is connected to a Data Collection Cabinet (PDMAR), which processes data before sending it to the Control Cabinet (PDMCR): up to 120 UHF sensors can be connected to each data collection unit. Thanks to a very small number of data collection cabinets, Power Diagnostix's GISmonitor can cover even the largest GIS, and its modular approach allows high scalability for future expansion of the switchgear.
The obtained and processed data are transmitted via a fiber optic ring network to the control unit (PDMCR), where the user can directly manage the system and have a complete overview of the GIS status. To ensure proper analysis of measured partial discharges, GISmonitor software provides a variety of functions and options. With the monitoring mode, the operator can access historical and real-time analysis of measured data over many years with just a click.
