Power limiter TVL series

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. •Fast response time •Efficient elimination of dangerous overvoltage to very low safe voltage values •Low residual voltage ensured by Metal Oxide Varistor (MOV) module •Temperature independent triggering voltage •Guaranteed recoverability for long term currents •Combined protection for personnel, passengers and equipment •Bidirectional operation for protection against overvoltages in both polarities
