摘要： A method of operating a generator set is disclosed. The method includes generating a current using a generator set, and stepping down the generated current to a stepped down current, using an internal current transformer. The method includes measuring the stepped down current using a current meter that may generate a current signal representative of the stepped down current. Further, the method includes generating a root-mean-square (RMS) value using a plurality of current values associated with the current signal. The method also includes generating a modified RMS value, using the current values that are greater than a predetermined current value. The method includes determining a measured value of the current generated by the generator set based on the RMS value and the modified RMS value. In addition, the method includes adjusting an operation of the generator set when the measured value exceeds an over-current threshold.
