automatic and protective relay

Reliability test and assessment for protective relays and automation equipments of power systems;

电力系统继电保护及自动化装置可靠性试验与评估

The development of electric power system makes the electromagnetic environment becomes increasingly harsh,and conversely the normal functions of relay protection and automation equipment are affected by the environment.

由于电力系统的发展,电磁环境变得越来越严酷,反过来要影响继电保护及自动化设备的正常功能。
