Abstract

This paper presents the design of DC protection Relay for Light Rail Transit system, which is very beginning product in domestic. Protection Function characteristic, principle and I/O interface including interlock signal has been introduced. The protection algorithm and EMC characteristics have been certified by official organization and Type test report has been introduced. Up to date in domestic, the test procedure for DC Protection relay hasn't been established so the new method and test equipment based on IEC regulations are proposed. Finally the product will be proved based on field test.
