AN IMPROVED DEVICE FOR MEASURING THE ELECTRIC POWER DRAWN BY A RAILWAY VEHICLE FROM A HIGH-VOLTAGE ELECTRIC SUPPLY LINE

摘要

A device (1 ) is disclosed that comprises a plurality of resistive voltage dividers (23a, 23b) connected operationally between a supply line (L) and an electric earthing terminal (22; 32c) so as to form separate respective connection paths to the electrical earthing terminal (22; 32c), and a processing assembly connected to the outputs (26a, 26b) of said voltage dividers (23a, 23b) and designed to generate signals or data indicating the voltage of said supply line (L). The processing assembly comprises a plurality of separate processing modules (41 a, 42a, 43a; 41 b, 42b, 43b) each one coupled to a respective one of the connection paths and designed to generate respective signals or data indicating the voltage of said supply line (L).
