As a high-voltage electrical system, the insulation performance and grounding reliability of photovoltaic power plants are the core foundations for ensuring personnel safety and stable equipment operation. During long-term outdoor operation, issues such as cable aging, water leakage from junction boxes, and damaged insulation layers of components can easily lead to decreased insulation performance, grounding faults, and safety accidents such as leakage, short circuits, and electric shocks. Suzhou LAILX focuses on the core requirements of photovoltaic electrical safety, and has ingeniously created the LXH601 insulation and grounding comprehensive tester, which integrates insulation testing, grounding testing, fault location, voltage and current detection, and other functions. With high-precision measurement, intelligent operation, and high safety design, it provides a one-stop solution for electrical safety testing of photovoltaic power plants, becoming the "all-round guardian" of electrical safety testing in the industry.
