Abstract: A method that tests a differential protection device having a first and a second differential protection chain includes: a step of controlling the flow of a test signal for a duration smaller than a no-trip time, and steps of determining the state of the two differential protection chains after the flow of a test signal, of monitoring the conformity of the evolution of the protection chains, and of determining the state of the test. The differential protection device includes two differential protection chains and controls the flow of a test current for a duration smaller than a no-trip time. It includes modules for monitoring the evolution of the protection chains and determining the state of the test in order to control the opening of an electrical unit if the test is good. The device can be included in the electrical unit.

Abstract: In this method, the voltage outage load-side is an opening of the circuit breaker, and the circuit breaker is able to interrupt the flow of electric current in an electric connection including an electric conductor. The auxiliary unit comprises a current sensor for measuring the intensity of the current flowing in the electric conductor and a first detection means for detecting the voltage outage load-side from the circuit breaker. The method comprises the following steps: measuring the intensity of the current flowing in the electric conductor, detecting the voltage outage load-side from the electric circuit breaker, determining a cause of the detected voltage outage load-side from the circuit breaker, said cause being selected from the group consisting in: an electric overload, a short-circuit and a voltage drop.
