Experimental Analysis of Hydrogen Online Monitoring Device for Low Oil Equipment

There is a lack of effective online monitoring methods for low oil equipment such as 750 kV bushings and current transformers in Xinjiang region. The hydrogen online monitoring device using palladium metal sensors can detect internal partial discharge, suspended discharge, and spark discharge faults in a timely manner, and is small in size and easy to install. This paper focuses on verifying the accuracy and response time of data in extreme environments, and then analyzes the comparison test results of eight hydrogen online monitoring devices in detail, demonstrates the effectiveness of installing hydrogen online detection devices in oil reduction devices, and selects the equipment of manufacturers with high accuracy.
