  • Determination of insulation resistance of an electric DC circuit
    Patent number: 8466691
    Abstract: A method for determining an insulation resistance of an electric DC circuit having at least a first and a second terminal includes performing a measurement cycle, verifying whether the change of a measured current exceeds a predetermined change rate, calculating a total insulation resistance, and calculating a first insulation resistance between the first terminal and a reference potential and a second insulation resistance between the second terminal and the reference potential. An insulation resistance measurement circuit is also provided for carrying out the aforementioned method.
    Type: Grant
