Adiradh offers GISmonitor Portable – Portable Partial Discharge Monitor as a reliable instrument for temporary partial discharge monitoring on gas-insulated switchgear. Moreover, it detects PD activity caused by hopping particles, floating potentials, cracks in insulators, or spacer defects. In addition, the system supports temporary measurements during testing and inspection tasks. Furthermore, its portable design enables fast installation across different GIS sections. Therefore, engineers can monitor insulation condition without permanent setup. Also, the instrument captures UHF signals and digitises them within microseconds. Consequently, it records even weak PD events accurately. However, external noise can affect PD results. Thus, the GISmonitor Portable connects to a disturbance antenna that supplies a gating signal. Moreover, this function separates PD pulses from disturbances in real time. As a result, users receive clean and reliable data. Finally, the system supports both AC and DC partial discharge analysis for flexible diagnostics.

The Power Diagnostix GIS monitor Portable serves as a compact solution for temporary PD monitoring on GIS. Moreover, it allows parallel real-time acquisition on up to 40 UHF channels. In addition, the instrument processes signals instantly to support fast fault detection. Furthermore, it works with embedded and retrofit UHF sensors commonly used in GIS installations. Therefore, users can integrate the system easily into existing assets. Also, the IPU2 input protection unit blocks strong transient signals. Consequently, the system maintains stable operation during switching events. However, PD monitoring requires clear signal separation. Thus, the disturbance antenna with gating removes external interference effectively. Moreover, users connect the instrument to a PC through USB or optional LAN. As a result, the software displays PD data from up to 24 sensors at the same time. Finally, compatibility with non-portable GIS monitor software ensures consistent data evaluation.

User manual for GIS monitor Portable – Portable Partial Discharge Monitor
The GIS monitor Portable is a UHF-based partial discharge monitoring instrument for gas-insulated switchgear systems. Moreover, it supports high-speed signal digitisation with microsecond resolution. In addition, the system performs parallel PD acquisition across up to 40 channels. Furthermore, it accepts signals from embedded UHF sensors and external retrofit sensors. Therefore, it suits different GIS designs. Also, the IPU2 input protection unit suppresses high-energy transients before signal processing. Consequently, the system protects sensitive electronics. However, UHF signals can attenuate over distance. Thus, the FCU2 frequency converter demodulates UHF signals into a lower frequency band. Moreover, this allows reliable signal transmission over longer cables. As a result, engineers can position equipment flexibly. Finally, the instrument connects to a PC for AC phase-resolved and DC time-based PD analysis using dedicated software.

The GIS monitor Portable uses UHF detection technology to identify partial discharge activity in GIS. Moreover, fast digitisation ensures precise pulse capture. In addition, parallel channel processing allows simultaneous monitoring of multiple sensors. Therefore, users can detect PD location trends more effectively. Also, disturbance gating separates real PD pulses from external noise in real time. Consequently, false indications reduce significantly. Furthermore, the IPU2 unit protects the system from strong transients during switching. Thus, measurement stability improves. However, field environments can be harsh. Therefore, the optional ICMoutlander protective housing supports reliable operation in severe weather. Moreover, the FCU2 unit enables signal demodulation for long-distance transmission. As a result, installation options increase. Finally, the software enables clear visualisation, comparison, and analysis of PD data under both AC and DC voltage conditions.
It is used for real-time partial discharge analysis on gas-insulated switchgear. The software displays parallel PD data from multiple UHF sensors, including trend plots, phase-resolved PD patterns, and time-based pulse analysis. Moreover, it allows users to compare sensor activity simultaneously to identify abnormal discharge behaviour. In addition, warning tables log PD events with time stamps, signal levels, and sensor identifiers. Furthermore, histogram and pattern views support noise separation and defect classification. Therefore, engineers can assess PD severity, locate sources, and track changes over time. The interface also supports AC phase-resolved and DC time-domain PD evaluation.
