Abstract： Electromagnetic relays are widely used in the fields of modern national defense, military, industrial automation and transportation. When the electromagnetic relays fail in the system, the reliable operation of the entire electrical system will be affected. In order to improve the reliability of the electrical system, it is necessary to test the characteristic parameters of the relay to evaluate its working performance and improve its stability. Aiming at the problem of easy failure of electromagnetic relay contact, this paper designs a set of online testing system of electromagnetic relay based on FPGA. The railway relay is used as a sample, the characteristic parameters of the relay are analyzed, and the time parameters which can reflect the degree of contact degradation are selected for testing. This portable online test system, which can be applied to multiple relay models, can detect the waveforms of voltage changes during relay suction and release in real time and store the data. It provides data support for the subsequent performance status evaluation of relays, and also provides reference data for the repair and maintenance of electromagnetic relays.
