Transformer partial discharge online monitoring system (pulse current method)

The anti-interference effect is remarkable. Researched and developed a dual-sensor directional coupling pulse identification system (two patented technologies) with independent intellectual property rights, and comprehensively applied multiple anti-interference methods such as digital filtering, phase windowing, and dynamic threshold to effectively eliminate or suppress interference and ensure acquisition The data is accurate and reliable. According to the principle of virtual instrument, adopt PC-DAQ system structure, LabVIEW programming, and realize various functions by software. It has powerful functions, strong flexibility, easy to expand multi-parameter monitoring and multiple equipment tour monitoring, and easy to maintain and upgrade. The system is safe, stable and easy to manage.
