Online monitoring technology mainly uses two methods: vibration analysis and partial discharge detection. The first is vibration analysis, and the second is partial discharge detection.
Gas chromatography (GC) technology is primarily used to analyze the internal components of gas mixtures. This detection technology boasts several advantages, including high efficiency, ease of use, and convenient operation. These advantages have led to its widespread application, particularly in the testing of various electrical equipment.
Sensor array technology plays a very important role in transformer fault detection.
Infrared spectroscopy technology, also known as online infrared spectroscopy detection technology, offers advantages such as high detection speed, high accuracy, high sensitivity, and low maintenance.
DC resistance testing technology for windings: By using DC resistance testing technology for windings, the longitudinal insulation and current loop connection of the windings in a transformer can be analyzed.
