MUMBAI, India, Oct. 11 -- Intellectual Property India has published a patent application (202441028667 A) filed by Mr. Makaram Narasimhan Ravinarayan; and Mr. Makaram Ravinarayan Suraj, Bengaluru, Karnataka, on April 8, 2024, for 'method of detecting leaky insulator on a transmission line tower and substation asset under charged condition.'
Inventor(s) include Mr. Makaram Narasimhan Ravinarayan; and Mr. Makaram Ravinarayan Suraj.
The application for the patent was published on Oct. 10, under issue no. 41/2025.
According to the abstract released by the Intellectual Property India: "A method for identifying a leaky electrical insulator (206) includes sensing leakage current flowing towards ground through each leg of a high-voltage structure or electrical grounding cables connected with each leg. A total leakage current for the high-voltage structure is determined by summing values of the leakage current flowing across each base. It is determined whether the total leakage current exceeds a predetermined threshold value of current associated with an operating voltage of the high-voltage structure. Upon determining that the total leakage current is exceeding the predetermined threshold value, an ultrasonic partial discharge detection is performed by directing an ultrasonic detector (302) towards each of the plurality of electrical insulators from the ground and collecting ultrasonic signals indicative of partial discharge activity. An electrical insulator is identified as the leaky electrical insulator (206) when the partial discharge activity is observed for the electrical insulator."
