MUMBAI, India, Nov. 7 -- Intellectual Property India has published a patent application (202547096451 A) filed by 3M Innovative Properties Company, Saint Paul, U.S.A., on Oct. 7, for 'sensored insulation plug.'
Inventor(s) include Gundel, Douglas B.; and Stollwerck, Gunther A. J.
The application for the patent was published on Nov. 7, under issue no. 45/2025.
According to the abstract released by the Intellectual Property India: "Sensored insulation plug (1, 2) for a medium voltage or high-voltage separable connector (10), operable to sense an elevated voltage, and comprising a plug body (140), a contact piece (175), connectable with the connector on elevated voltage, an embedded discrete coupling capacitor (151), and an integrated sensing capacitor (150), operable as a high-voltage capacitor in a sensing voltage divider for sensing the elevated voltage and comprising a high-voltage electrode (162), a tubular sensing electrode (170), embedded in the insulating material (610) and arranged around an axial section of the high-voltage electrode; and a dielectric (180). The coupling capacitor (151) comprises a coupling electrode (160), connected to the contact piece, and an opposed counter electrode (171) and is operable to harvest energy, superimpose signals over the elevated voltage, extract signals from the elevated voltage, detect a partial discharge signal in the elevated voltage, detect the presence or absence of an elevated voltage, sense an elevated voltage at a low accuracy or detect a zero crossing of the elevated voltage."
The patent application was internationally filed on Mar. 25, 2024, under International application No.PCT/IB2024/052850.
