MONITORING DEVICE FOR POWER TRANSFORMERS Russian patent published in 2017 - IPC H02H7/04 

FIELD: electricity.

SUBSTANCE: device has a control unit 20 of the partial discharge, vibration control unit 21 and the transformer block colour visualization of the transformer technical condition of 22 levels. Continuous recording of the level and distribution of partial discharges in isolation bushings, coil, and magnetic circuit to determine the place of origin of the partial discharge and insulation failure mechanism. Control parameters of the vibration of the walls of the power transformer load tap changer tank and the body in real time allows you to determine the status of the compact coil and magnetic circuit. Specifying classification level technical condition of the transformer and the implementation of a light-signaling alert attendants different colour signals can improve the accuracy and timeliness of informing staff about the severity of deviations of parameters from the set limits.

EFFECT: enhanced functionality and increase the reliability of the power transformer through the implementation of a comprehensive work on the diagnostic monitoring main working transformer parameters in real-time assessment of defects of development and the level of danger of accidents, localization and identification of faults in the isolation transformer and the device voltage regulation under load, promptly informing staff about the level of deviation from the prescribed limits and severity of accidents.
