저압 전원용 서지보호장치(surge protective devices) 기술

A new standard on a developing market A new document taking account of varied aspects of photovoltaic generators and technologies is available, designed EN 50539-11, to define specific surge protection to photovoltaic installations. According to the very specific characteristics of PV generators and PV installations with high voltages and low DC current, the EN 50539-11 introduces the idea of testing the behavior of photovoltaic surge protective devices on end of life for the safety of the equipments.
