MUMBAI, India, March 14 -- Intellectual Property India has published a patent application (202517133359 A) filed by Siemens Mobility Gmbh, Munchen, Germany, on Dec. 30, 2025, for 'method and assembly for inspecting an insulation.'
Inventor(s) include Sanger, Goran; and Stark, Thomas.
The application for the patent was published on March 13, under issue no. 11/2026.
According to the abstract released by the Intellectual Property India: "The invention relates to a method for inspecting an insulation on the basis of at least one first insulation inspection device, which can be connected to a first and second measuring connection, when electric energy is supplied to an electrically driven vehicle, in particular by means of an overhead line, using a supply voltage, wherein the insulation inspection device is designed to be connected to the supply circuit via the first and second measuring connection for inspection purposes and is designed to operate up to a specified maximally permissible nominal voltage peak value. An electric circuit assembly is connected between the supply of electric energy and the insulation inspection device in an electrically conductive manner, said circuit assembly being dimensioned such that in the event of a first value of the supply voltage which lies above a second value of the nominal voltage, the voltage which is allotted to the insulation inspection device is limited to the second value. The circuit assembly is additionally dimensioned such that at least the resistance value of the internal resistance of the insulation inspection device, said internal resistance being produced when the supply of electric energy is connected, is taken into consideration such that the measurement time for the measurement of an insulation resistance which occurs in the event of a fault can not exceed a fixed maximum time. The invention additionally relates to a corresponding assembly for carrying out the method."
The patent application was internationally filed on May 24, 2024, under International application No.PCT/EP2024/064331.
