  • GDPD-PTU  PD Online Monitoring System for Oil Transformer

    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.

     With the continuous expansion of the power grid, it is becoming increasingly important to improve the safe operation level of electrical equipment, carry out online monitoring of partial discharge of transformers, analyze the insulation status of transformers in combination with intelligent diagnostic expert systems, and determine the nature of insulation defects in a timely manner.
