As a high-voltage electrical system, photovoltaic power plants are exposed to complex outdoor environments for a long time, and problems such as cable insulation aging and grounding device corrosion and failure can easily lead to safety accidents such as leakage, short circuits, and lightning strikes. Traditional testing equipment has a single function and requires the cooperation of multiple instruments to complete insulation, grounding, and other tests. This not only reduces efficiency, but also increases maintenance costs and human error risks. Shanghai LAILX focuses on the pain points of photovoltaic electrical safety testing and has launched the LXH601 comprehensive insulation and grounding tester, which has the full dimensional testing capability of "one machine, eight capabilities" to build a solid electrical safety defense line for photovoltaic power plants. Leakage current test

LXH601 completely breaks the limitations of traditional equipment's "one machine, one use" approach, integrating eight core functions: insulation resistance testing, grounding resistance testing, equipotential continuity testing, AC/DC voltage testing, polarity testing, Voc testing, Isc testing, and insulation fault location. Operation and maintenance personnel do not need to frequently switch equipment and wiring, and can complete comprehensive electrical safety inspections of photovoltaic modules, inverters, combiner boxes, cable lines, grounding devices, etc. in one deployment, with a single inspection efficiency increase of over 40%. In terms of insulation testing, the equipment supports 1500V high-voltage live testing, using dedicated active compensation technology to eliminate photoelectric current interference and truly reflect the insulation status of the system's working state; The grounding resistance test adopts the four pole method, effectively eliminating the influence of soil and lead resistance, with an accuracy of ± 2%, ensuring the reliable conduction of the grounding system.

Intelligent fault location is another highlight of LXH601. The device is equipped with an intelligent insulation fault location module, which can accurately lock the specific location of the fault in the string through percentage values and display it intuitively in the APP, without the need for step-by-step troubleshooting, greatly reducing the time for fault handling. The whole machine weighs only 2.8kg and adopts an IP54 dustproof and waterproof design, which can operate stably in extreme environments ranging from -10 ℃ to 50 ℃, perfectly adapting to various power plant scenarios such as mountains, deserts, rooftops, etc. The built-in large capacity lithium battery supports 8 hours of battery life, meeting the needs of all day outdoor inspections.

From power station construction acceptance to daily operation and maintenance inspection, LXH601 provides comprehensive protection for the electrical safety of photovoltaic systems with its core advantages of multifunctional integration, high-precision detection, portable intelligence, and safety and reliability. LAILX adheres to the concept of "safety first, innovation driven" and continues to deepen its expertise in electrical safety testing technology. The launch of LXH601 not only improves operation and maintenance efficiency, but also provides a solid guarantee for the safe and sustainable development of the photovoltaic industry.
