  • Method for detecting earth-fault conditions in a power conversion apparatus
    Patent number: 10845427
    Abstract: A method for detecting earth-fault conditions in a power conversion apparatus including the following steps: acquiring a first detection signal indicative of an earth-leakage current flowing between the power conversion apparatus and the ground; processing the first detection signal to calculate a first processing signal indicative of a time variant component of the earth-leakage current for one or more selected frequency bands of interest; processing the first detection signal to calculate a second processing signal indicative of a time-invariant component of the earth-leakage current; processing the first and second processing signals to calculate a third processing signal indicative of a resistive component of the earth-leakage current; and processing the third processing signal to determine whether earth-fault conditions are present.
