Research & standards committees publish many standards relating to surge risk & immunity. These standards however differ from one geography to another. Of importance is that there are two basic low voltage standards in the world. In the U.S. it is Vac, 60Hz. (half the voltage & twice the current). These high-capability varistors will clamp the voltage at a level sufficiently low - typically V in a V system under a surge of 10 kA, or V in a V system for the same 10 kA surge (by comparison, conventional arresters have a protective level of 2 to 3 kV). medium-voltage surge arresters of the 3EJ product family with high energy discharge capabilities The medium-voltage portfo-lio is completed with the 3EQ0, a medium-voltage surge arrester with directio-nal pressure relief device Siemens launches the 3EL3, the strongest silicone housed cage design surge arrester available in the market History.

SURGE ARRESTERS AND LOW VOLTAGE LIMITING DEVICES FOR D.C. RAILWAY NETWORKS The descriptions A1 and A2 define the function of the MO-arresters. Function A1: Overvoltage protection of the equip-ment and apparatus connected to the traction supply voltage. The MO-arresters are connected between the traction supply voltage (overhead.
