In case of overvoltage, the RVL limits the dangerous voltage to very low safe values. Additionally, in case of faults (e.g. accidental short-circuits with the contact lines), the RVL generates a durable conductive path between the overloaded area and the substation. This results in increased current loads that are sensed at the substation, allowing an efficient tripping of the safety circuit breaker.

In case of overvoltage, the TVL limits the dangerous voltage to very low safe values. In addition, in case of faults (e.g. accidental short-circuits with the contact lines), the TVL generates a durable conductive path between the overloaded area and the substation. This results in increased current loads being sensed at the substation, allowing an efficient tripping of the safety circuit breaker.

When impermissible touch voltage is developed, the RHP-SCD limits it to very low safe values by efficiently short-circuiting the negative rail and the earth. The programmable automatic opening of the RHP-SCD limits the effects of stray currents. In case of insulation faults (e.g. accidental short-circuits with the contact lines), the RHP-SCD generates a durable conductive path between the overloaded area and the substation and is able to carry the traction fault current until the fault is cleared by the traction high speed circuit breaker. Embedded state-of-the-art protection technology against lightning and transient overvoltage guarantees optimum equipment protection.
