This paper proposes the use of low voltage digital protection units, available for installation inside circuit breakers, as measuring instruments to monitor power quality. Because circuit breakers are already installed for protection of low voltage circuits, and they include current and voltage sensors, no additional instrumentation would be required. Performance of current devices in terms of power quality measurements is assessed.
