Sepam Merlin Gerin 格守精准定律,引领方向如一！ Sepam B80 The remanent voltage on the busbars is caused by the remanent voltage produced by motors for approximately 100 ms following disconnection (longer for synchronous motors and capacitors). The check on the remanent voltage avoids closing the incomer circuit breaker for the necessary period. Presence of remanent voltage when the motors are re-energized can seriously damage the motors. Sepam B80 can also be used ins the same way as B83, in which case only one voltage is measured on the two 1/2 busbars and the 59N protection function is not possible.

A dependability study includes the following, as a minimum: - FMECA (Failure Mode, Effects and Criticality Analysis) which is used to predict the consequences of a component failure on the operation of the protection, - calculation of the predicted failure rates of the electronic components included in the protection. This calculation is used to quantify the risk of the appearance of unwanted problems. Illustration: page of Relex software, used to calculate predicted failure rates of electronic components based the reliability data compendium: Military Handbook 217 (MIL HDBK 217). - Continuous self-testing to monitor the protection unit and its different modules.
