GB/T 25890.9-2010 Railway applications—Fixed installations—DC switchgear—Part 7-3: Measurement, control and protection devices for specific use in d.c. traction systems—Isolating voltage transducers and other voltage measuring devices
Abstract
This part of GB/T 25890 specifies the requirements for isolation voltage transmitters and other voltage measurement equipment used in DC facilities and ground devices of rail transit systems.
Transmitters are typically installed between the sensors or rails of the primary-side equipment in the distribution panel and the secondary-side equipment, providing electrical insulation for the input and output.
