Railways can be damaged by sudden overvoltage impulses. Therefore, voltage on railway<\/strong> lines must be kept at certain levels, and overvoltage limiters should be used.<\/p>\n

Raycap TVL<\/strong> complies with the railway standard for EN 50526-2 voltage limiting devices. Depending on the application, as described in EN 50122-1, it may include VLD-F, VLD-O, or requirements for both types. The device is typically connected between the rail systems and the railway ground. It can be installed with mounting brackets in special panels on catenary poles to protect multiple signaling<\/strong> or telecommunication<\/strong> equipment at passenger stations, workshops, and other critical points.<\/p>\n

\"raycap-tvl\"<\/a>

It can be installed with or without mounting brackets in special cabinets on catenary poles to protect multiple signaling or telecommunication equipment at passenger stations, workshops, and other critical points.<\/p><\/div>\n

\n

In case of overvoltage<\/strong>, TVL limits the dangerous voltage to very low safe values. Moreover, in case of faults or accidental short circuits with contact lines, the voltage is limited.<\/p>\n<\/blockquote>\n

How Does Raycap TVL Work?<\/strong><\/h2>\n

It creates a conductive path between the overloaded area and the substation. This leads to increased current loads detected at the substation, allowing the safety circuit breaker to trip quickly.
\nIts function relies on the coordinated operation of both a metal oxide varistor (MOV) surge suppression block and a controlled thyristor block.<\/p>\n
