Online Partial Discharge Monitoring System – GISmonitor

Adiradh offers the Online Partial Discharge Monitoring System – GISmonitor for continuous insulation condition monitoring of gas insulated switchgear. Moreover, the system enables real-time partial discharge monitoring under normal operating conditions. Therefore, utilities assess GIS health without outages. In addition, the system supports early detection of insulation defects. Also, it delivers stable and continuous data acquisition. Furthermore, the system is designed for permanent installation on GIS assets. However, operation remains simple and structured. Consequently, maintenance teams gain clear insight into discharge activity. As a result, teams plan maintenance actions in advance. Thus, the system helps reduce unexpected GIS failures. Moreover, the platform supports long-term trend analysis. In addition, it integrates with existing UHF sensors and monitoring infrastructure. Also, clear visualization improves decision-making. Finally, the GISmonitor supports reliable online partial discharge monitoring, therefore improving GIS reliability and supporting condition-based maintenance strategies.

Overview

The Online Partial Discharge Monitoring System – GISmonitor is developed for continuous monitoring of partial discharge activity in gas insulated switchgear. Moreover, the system operates while GIS remains energized. Therefore, it captures true operating conditions accurately. In addition, the platform supports multiple UHF sensor inputs for flexible configuration. Also, it enables parallel data acquisition from several monitoring points. Furthermore, the system supports phase-resolved partial discharge analysis for defect recognition. However, advanced noise separation ensures stable and clear measurements. Consequently, the system distinguishes internal PD signals from external interference. As a result, insulation degradation trends become visible at an early stage. Thus, utilities improve asset reliability and maintenance planning. Moreover, the system supports centralized monitoring architectures. In addition, it allows remote data access and visualization. Also, the scalable design supports future system expansion. Finally, the GISmonitor provides a reliable solution for online GIS partial discharge monitoring.

About Product

The GISmonitor is an online partial discharge monitoring system designed specifically for gas insulated switchgear using UHF measurement technology. Moreover, it processes fast transient electromagnetic PD signals captured by embedded or external UHF sensors. Therefore, it enables accurate detection of internal GIS defects. In addition, the system supports phase-resolved partial discharge (PRPD) analysis and time-based trending. Also, it evaluates parameters such as pulse amplitude, repetition rate, and phase position. Furthermore, advanced digital signal processing and gating reduce electromagnetic interference. However, measurement sensitivity remains stable during continuous operation. Consequently, the system detects low-level discharge activity reliably. As a result, defects such as particle discharge, surface discharge, and insulation degradation can be identified. Thus, the GISmonitor supports technical diagnostics using established PD terminology for long-term GIS insulation condition assessment.

Technology & Benefits

The GISmonitor uses high-speed digital acquisition to continuously capture UHF partial discharge signals. Moreover, synchronized phase reference ensures consistent PRPD evaluation. Therefore, the system tracks discharge behavior accurately over time. In addition, digital filtering enhances signal clarity. Also, noise gating separates PD activity from external disturbances. Furthermore, continuous data logging supports long-term trend evaluation. However, system stability minimizes measurement drift. Consequently, users compare results reliably across extended periods. As a result, early insulation degradation becomes visible. Thus, maintenance strategies shift from reactive to condition-based approaches. Moreover, centralized monitoring supports fleet-level GIS supervision. In addition, the modular architecture allows easy system expansion. Also, standardized data output simplifies reporting and analysis. Finally, the GISmonitor delivers reliable online partial discharge monitoring, therefore improving GIS availability and reducing unplanned outages.
