About Online Partial Discharge Monitoring system on GIS

GISmonitor builds on more than 20 years of experience in online PD monitoring on rotating machines, transformers, cables, and especially GIS systems. It combines proven technology of the ICMmonitor with new processor technology and embedded hardware capabilities. The hardware core of the system has been optimized for parallel, real-time PD acquisition on multiple channels. Any UHF signal can be detected and digitized within microseconds. A separation of PD events from external disturbances or internal switching pulses is calculated in real-time and, therefore, an effective PD and alarm detection is given.

Each 8-channel acquisition plug-in board operates fully stand alone but can be combined with a virtually unlimited number of units, to monitor all PD sensors in one or even multiple GIS in parallel. A full 19" sub-rack carries 64 channels. A remote computer reads all data of the instruments via the high speed fiber optic LAN ring, providing communication redundancy. The GISmonitor indicates with on-board LEDs internal states and alarm conditions

The unit is moisture, dust, and corrosion resistant, operating within a wide temperature range and harsh environments.

FAQ's of Online Partial Discharge Monitoring system on GIS:

Q: How does the system detect partial discharge in GIS equipment?

A: The system uses UHF, TEV, and Acoustic Sensors to capture partial discharge signals from gas insulated switchgear (GIS). Its advanced PD pattern recognition software analyzes these signals in real time, identifying insulation faults with high accuracy.

Q: What are the installation options available for this monitoring system?

A: Installation is flexible, offering clamp-on and bolt-on methods suitable for different GIS panel sizes. The enclosure's customizable dimensions ensure compatibility with a variety of GIS configurations.

Q: When should I use online partial discharge monitoring on GIS?

A: Continuous monitoring is recommended for preventive maintenance and early fault detection. It is especially useful during commissioning, after retrofits, or in routine monitoring frameworks to prevent accidental shutdowns and costly repairs.

Q: Where is the data from the monitoring system stored and how is it accessed?

A: All diagnostic data and event logs are stored in the system's 32 GB internal memory. Users can access data remotely via Ethernet, RS485, optional wireless connections, or through the integrated 7-inch LCD touch panel. Reporting and analysis can also be managed using advanced onboard software.

Q: What is the process if the system detects a partial discharge event?

A: Upon detecting a PD event, the system activates configurable visual and audible alarms. It records detailed, time-stamped event data and can notify maintenance teams instantly through remote monitoring interfaces for immediate attention.

Q: What are the primary benefits of using this online PD monitoring system?

A: Benefits include enhanced GIS reliability, reduced downtime, early insulation fault detection, and support for condition-based maintenance. The system also ensures safety compliance, detailed diagnostics, and improved asset management decisions through actionable insights.
