<p>Disclosed is a duplex system for measuring and outputting at least one from among a voltage and a current. A first measuring unit measures at least one from among a voltage and a current. A second measuring unit measures at least one from among a voltage and a current. A control unit releases the connection with the first measuring unit when the first measuring unit malfunctions, and changes over to the second measuring unit. A filter filters and outputs the measured value of the second measuring unit based on the measured value of the first measuring unit.</p> |
