Delivering comprehensive, reliable and robust online monitoring, GE’s Multiple Gas Transformer DGAs enable full remote diagnostics and assured decision-making.

Integrating DGA measurement, additional sensors, analysis models and data handling features to address the majority of prevalent failure modes, this cost-effective solution delivers essential condition assessment tools.

Benefits

• Modular and retrofittable architecture using selectable standard add-on cards
• Provides extensive remote insight into transformer condition and safe operation
• Enables correlation of data for validation and in-depth fault analysis
• Models with a graphical presentation using built-in web-page-based HMI and local colour screen available
• Issues can be detected in their infancy, avoiding unexpected failures and facilitating planned outages
• Models featuring integration with GE’s acclaimed Perception™ Fleet asset management software are available
• Integrated DGA and bushing monitoring

Delivering cost-effective, optimised, low-maintenance monitoring devices, the field-proven DGA monitoring solutions, provide continuous monitoring of gas and moisture levels to alert users of developing faults and minimise the risk of unplanned outages.

GE’s DGA devices can also come as a UL certified, HazLoc version for installation on transformers in hazardous locations.

Benefits

• Support for asset performance management software analytics, enabling fleet-level deployments
• Extending beyond DGA monitoring, through the connection of sensors, monitoring other parameters
• Provides critical data, facilitating the planning of site intervention and maintenance activities
• Easily upgraded to accept analogue signals and monitor other key parameters
• Integrated display and keypad for simplified local user interaction and data visualisation
• Sensors are available as a traditional Hydran composite gas (H2, CO, C2H2, C2H4) sensor or a discrete Hydrogen only (H2) sensor
• Compatible with GE’s Perception™ software to trend and analyse transformer health data

A cost-effective, compact, modular, online monitoring solution, the GE CB Watch is suitable for high-voltage circuit breakers.

The GE CB Watch records information using non-invasive sensors to detect and trend leaks early and monitor operational parameters in real-time to warn of any significant change in performance, assembling an overall condition assessment of the breaker.

Benefits

• Computation of Switchgear Health Index for condition-based asset management strategy
• Compact and modular solution adaptable to most circuit breaker types
• Improved circuit breaker operational availability and lack of surprises
• Enables health/condition-based asset replacement strategy
• Delivers reduced and optimized operating maintenance costs
• Help reduce costly SF6 gas losses into the environment

Bushings account for a large proportion of High Voltage (HV) substation failures, often causing severe and costly damages.

GE’s advanced Intellix™ BMT 330 is an online system that continuously monitors the condition of the bushings and can also detect developing partial discharge (PD) activity in the transformer main tank. It will alert personnel of fault conditions at an early stage and provide vital health information on the bushings and the transformer.

Benefits

• Comprehensive monitoring of transformer bushings and PD activity on a bank of single-phase transformers
• One product combining advanced online continuous bushing monitoring and partial discharge activity in the main tank
• GE’s Perception™ is used for bushing information, PD activity and DGA data analysis, resulting in familiar easy-to-use information
• Minimising administrative burden, lowering the total costs
• Can be integrated with GE’s Kelman TRANSFIX Dissolved Gas Analysis (DGA) multigas analyser for an in-depth view of the transformer’s condition and the root cause of major failures
