T/SMA 0047-2024 The method for testing the surface transfer impedance of high-voltage shielded cables and connectors for rail transit
Abstract
Main technical content: This document specifies the shielding efficiency test procedures and technical methods for high-voltage shielded cables and connectors in rail transit, with a test frequency range of 9 kHz to 30 MHz (which can be extended according to the length of the tested cable and the test device). The test methods specified in this document are applicable to all types of vehicles defined in GB/T 2900.36-2021, such as high-speed trains, locomotives, passenger cars, subways, light rail vehicles, trams, and medium- and low-speed maglev trains, etc.
