RVL Voltage Limiting Device

RVL voltage limiting devices limit the dangerous voltage that can be developed in railway networks to very low safe values. In fault cases such as accidental short-circuits with the contact lines, the RVL solution generates a durable conductive path between the overloaded area and the substation, resulting in increased current loads being sensed at the substation, allowing an efficient tripping of safety circuit breakers.
