Abstract
An electrical equipment includes a calculator or a data concentrator for connecting to a tachometer via a cable that includes a measurement wire and a test wire. The electrical equipment has a measurement input to which the measurement wire can be connected and a test input to which the test wire can be connected, measurement acquisition components connected to the measurement input and arranged to acquire an electrical measurement signal present on the measurement wire and produced by the tachometer, test acquisition components connected to the test input and arranged to detect whether the test wire is or is not open-circuit, and processor components arranged to detect a break of the measurement wire if the test wire is open-circuit.
