RL Protect

Description

The RL-PROTECT is the new answer from GILLAM-FEI to the railway traction network protection demand.  It is a numeric protection system equipped with a bidirectional amperemetric unit and a voltmetric unit.
The same equipment realizes electrical protection, oscillo-perturbography and history recording through a modern and user friendly interface.

RL-PROTECT is a digital relay designed to offer a complete over-current protection for DC metro and railways feeders.  RL-PROTECT is connected to isolated transducers to monitor the feeder current and voltage. A large panel of customizable conditions allows exhaustive detection of different types of line faults.
