Abstract

The present disclosure relates to a RMS detector for directly computing a signal detected through an analog circuit to measure its RMS value, and a circuit breaker using the same. For this purpose, a RMS detector according to the present disclosure may include a plurality of voltage/current sensing units configured to detect a voltage or current shaped analog signal for an arbitrary load; a plurality of square circuit units configured to compute square function units, respectively, based on a voltage output from the plurality of voltage/current sensing units; a summing circuit unit configured to sum a plurality of output voltages output from the plurality of square circuit units, respectively; and a root circuit unit configured to compute a RMS value based on a voltage output from the summing circuit unit.
