Product Solutions / Voltage Limiting Devices / TVL Voltage Limiting Device News Events Careers Resources Search for: EN DE Product Solutions Company Contact TVL VOLTAGE LIMITING DEVICE TVL Voltage Limiting Device In the case of overvoltage events in railway networks the TVL products limit the dangerous voltage to very low safe values. In fault cases such as 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. The TVL is adapted for installation in urban railway infrastructure structures.

Product Solutions / Surge Monitoring News Events Careers Resources Search for: EN DE Product Solutions Company Contact SURGE MONITORING Surge Monitoring Surge Counters & Monitors – ProGRID Surge currents can cause loss of data transmission, switch tripping, disturbance of machine control systems and a slow but noticeable degradation of circuit elements. In addition, a surge can be an indicator of a short circuit which causes currents of power to travel along unintended paths with little or no electrical impedance, for example after a blackout or wiring insulation damage. Raycap’s ProGRID surge and lightning counter solutions have various capabilities that can sense, record and transmit the occurrence of otherwise undetectable surge currents, enabling users to take preventive measures and plan appropriate maintenance.
