Photovoltaic power plants are usually built in open fields and exposed to harsh environments such as thunderstorms, high temperatures, and high humidity for a long time. The safety of the electrical system is crucial. The problems of insulation aging and poor grounding are like "time bombs" lurking inside the power station. Once they explode, they can cause equipment to trip and shut down, and in severe cases, they can lead to fires and even personal electric shock accidents. With the continuous improvement of voltage levels in photovoltaic systems (such as the popularity of 1500V systems), more stringent requirements have been put forward for the accuracy and safety of insulation detection equipment. In this niche field, traditional electrical testing giants such as Fluke and Nichi still dominate the high-end market, while some domestic brands such as Ulide and Shengli Instrument provide basic products. However, in the face of the unique DC high voltage environment and complex grounding network of photovoltaic systems, general-purpose instruments often appear inadequate, with cumbersome operations and difficult data interpretation.

The Shanghai LAILX Insulation Grounding Comprehensive Tester LXH601 is a "Electrical Safety Guardian" specially designed for photovoltaic systems. The biggest breakthrough of LXH601 lies in its special optimization for the photovoltaic DC side. It can accurately measure the insulation resistance of the DC side to ground online without affecting the normal operation of the power station, and effectively identify the hidden danger of DC arcing. The frequency conversion anti-interference technology adopted can effectively filter out the complex electromagnetic noise on the power plant site, ensuring stable and accurate test data output even in strong interference environments.

In terms of grounding testing, LXH601 supports multiple testing methods and can adapt to the measurement needs of grounding resistance under different geological conditions. The large-sized high-definition touch screen equipped with it presents complex electrical parameters in an intuitive graphical interface, making it easy for even non electrical operation and maintenance personnel to get started. In terms of safety, LXH601 has multiple protective designs, including high-voltage alarm, automatic discharge and other functions, to maximize the personal safety of operators. For power plant acceptance, regular safety inspections, and troubleshooting, LXH601 is not only a testing instrument, but also a necessary legal and technical certificate for compliant operation and risk avoidance of power plants, providing a solid "insulation armor" for photovoltaic assets.
