Electromagnetic Oscillation & Event Inference Based Transformer Safety Pre-control

Intelligent safety pre-control of large transformers based on electromagnetic oscillation monitoring and event reasoning: Based on the mechanism of electrical and mechanical fault events of transformers, with the help of the "electromagnetic oscillation" matrix for judgment, it ensures the safe operation of large transformers: Applying the principle of electromagnetic oscillation to fault diagnosis; Introduce intelligent monitoring technology for microcurrents in transformer core grounding to promptly detect abnormal micro-discharges. Deeply develop the online intelligent diagnosis function of transformer chromatography; Develop an expert knowledge base for various internal and external faults of transformers, and establish multi-source coupling analysis and diagnosis models for electromagnetic oscillation, chromatography online and microcurrent.

Product Details

Key Technologies

◆Scope: Within the high and low voltage bushings of the transformer. Monitoring: Covers UHF partial discharge, core current, electromagnetic oscillations, and oil chromatography analysis. Analysis & Decision-Making: a. The UHF unit sensitively captures internal and external discharge faults within the transformer. Any abnormal discharge detected within the monitored range triggers an early warning. b. A micro-current sensor for core grounding detects "additional" induced current and issues an alarm. c. An electromagnetic oscillation sensor matrix is deployed to synchronously collect and directionally analyze "electromagnetic oscillation" signals. Matrix scanning locates the "discharge fault" point, continuously assesses the severity, and recommends operational strategies. d. Oil chromatography gas analysis continuously monitors the degradation of insulating oil composition, enabling qualitative analysis of significant discharge faults, confirming the "fault severity" level, and providing recommendations on whether to shut down the unit.

: Expected effect

◆Realize the diagnosis and early warning of latent faults during the operation of transformers, and promptly push operation and maintenance suggestions to prevent major damage accidents to transformers. ◆Timely identify internal and external faults of the transformer, such as winding deformation, core faults, as well as internal and bushing discharge faults of the transformer for monitoring and early warning. ◆Monitor and warn of faults such as moisture or damage to the insulation inside the transformer, multi-point grounding of the core, foreign objects in the box, and sludge deposition in the oil tank.
