GDPD-PTU PD Online Monitoring System for Oil Transformer
The aging and damage of the internal insulation of the transformer mostly starts from local discharge. The reason for local discharge is that the electric field is too concentrated at a certain point, or the electric field strength at a certain point is too large. At present, the main methods for detecting transformer local discharge faults are: UHF ultra-high frequency monitoring method, HFCT high-frequency pulse current local discharge measurement method (pulse current method), ultrasonic local discharge measurement method (ultrasonic method), and oil gas chromatography analysis method.
