Photovoltaic power plants are exposed to complex outdoor environments for a long time, and factors such as humidity, dust, and aging can easily lead to a decrease in equipment insulation performance and insufficient grounding reliability, which in turn can cause safety accidents such as leakage, short circuits, and fires, threatening personnel safety and stable operation of the power plant. Traditional testing equipment has a single function, complicated operation, weak anti-interference ability, and requires multiple instruments to be carried back and forth for operation. The detection efficiency is low and the data correlation is poor, making it difficult to meet the electrical safety detection needs of photovoltaic systems in all scenarios. LAILX in Suzhou is deeply engaged in the field of photovoltaic electrical safety testing. Based on years of technological accumulation, it has launched the LXH601 comprehensive insulation and grounding tester, which integrates multiple functions, high-precision testing, intelligent operation, and strong environmental adaptability to create an "all-round guardian" of photovoltaic system electrical safety. It builds a solid safety defense line in all dimensions and empowers the safe and efficient operation and maintenance of photovoltaic power plants. Leakage current test
