Dissolved Gas Analysis
CSE W Arthur Fisher’s Dissolved Gas Analysis solutions support critical asset performance with continuous monitoring and real-time, intelligent insights.
Continuous monitoring and analysis for optimised transformer performance
Transformers are critical components of the electrical grid and understanding their condition is essential to preventing failures and unplanned outages. Dissolved Gas Analysis (DGA) is a proven method for detecting insulation stress and developing faults by analysing gases dissolved in transformer oil.
In collaboration with GE Vernova, CSE WAF delivers advanced DGA solutions that provide continuous, real-time monitoring of transformers, circuit breakers, and bushings. These systems deliver early fault detection and actionable alerts, enabling timely intervention before issues escalate, while optimising reliability and reducing maintenance costs.
Applications
Medium to large sized transformers
DGA is a critical tool for fault detection and predictive maintenance, supporting the long-term reliability and efficiency of medium to large power transformers.
Utility and industrial transformers
Designed to meet the specific demands of both utility and industrial environments, our DGA solutions offer flexible, scalable monitoring. When integrated with protection relays and supporting technologies, they provide comprehensive analysis of transformer health through synchronised chemical and electrical measurements.
Transmission transformers
By continuously tracking gas concentrations and fault trends, DGA enables operators to assess insulation condition, plan proactive maintenance, and extend transformer life, minimising downtime and improving network resilience.
Leading Analysis Solutions
Selecting the right Dissolved Gas Analysis solution is critical to protecting people, assets, and maintaining operations. CSE WAF provides specialist support to help identify the most suitable technologies based on specific risks, application demands, and environmental conditions to meet your site’s requirements and seamlessly integrate into existing infrastructure.
