Abstract: In order to raise the reliability and correctness of monitoring data for transformer online monitoring device, this paper carried out statistical analysis of transformer equipment state monitoring technology’s application situations based on state grid company investigation and study materials, as well as state monitoring device’s reliability and validity. This paper gave the total disposition principle and the preferred selection and evaluation method. The transformer online monitoring project was raised to recommend installing oil spectrum monitoring device and iron core grounding current monitoring device with partial discharge line detection instead of online monitoring etc.
Key words: transformer; online monitoring; fault; dissolved gas analysis; iron core grounding current; partial discharge
