As a high-voltage electrical system, photovoltaic power plants are exposed to complex outdoor environments for a long time. Insulation performance and grounding reliability are the core cornerstones to ensure personnel safety and stable equipment operation. With the development of the photovoltaic industry towards high voltage and large capacity, higher requirements have been put forward for the professionalism, accuracy, and convenience of electrical safety testing equipment. Suzhou LAILX focuses on industry pain points and has launched the LXH601 comprehensive insulation and grounding tester, which integrates multifunctional detection, high-precision measurement, and intelligent operation, providing a comprehensive solution for insulation and grounding detection of photovoltaic power plants and various electrical systems, and building the first line of defense for electrical safety.

LXH601 is specially designed for electrical safety testing of photovoltaic systems, with comprehensive functions covering core requirements such as insulation resistance testing, grounding resistance testing, protection conductor continuity testing, DC voltage testing, and ground fault location. One device can complete the entire process of electrical safety testing for photovoltaic power plants, replacing traditional multiple single function devices and greatly improving testing efficiency. In terms of insulation resistance testing, it supports multiple DC test voltages of 250V, 500V, 1000V, and 1500V, with a measurement range of up to 0~199.9M Ω, meeting the high voltage insulation testing requirements of 1500V photovoltaic systems. Equipped with two modes of DUAL bipolar testing and TMR unipolar testing, it can sequentially measure the positive and negative pole to ground insulation resistance of photovoltaic modules, and continuously measure the grounding insulation resistance of modules, adapting to different detection scenarios. At the same time, advanced testing algorithms are used to ensure measurement accuracy of ± 5% reading+3 digits, accurately determining whether the insulation performance meets the standards.

Grounding resistance and continuity of protective conductors are key indicators for safe grounding in photovoltaic power plants, and LXH601 performs outstandingly in this regard. The continuity test of protective conductors supports two levels of testing currents, 200mA and 7mA, with a measurement range covering 0.00 Ω~1999 Ω and an accuracy of ± 2% rdg ± 2 Ω. It accurately detects the connection reliability of grounding conductors, equipotential conductors, and grounding rods. The grounding resistance test adopts advanced three pole and four pole methods, which are suitable for different soil environments and testing requirements. The measurement range is wide and the accuracy is high, effectively avoiding the error problems of traditional grounding testing. What is particularly outstanding is that the equipment has a powerful ground fault location (GFL) function, which can accurately locate the specific location of insulation damage and grounding faults in the photovoltaic string, without the need for step-by-step troubleshooting, greatly reducing the time for fault troubleshooting and lowering the difficulty of operation and maintenance.

Intelligent and convenient design makes LXH601 an efficient assistant for on-site inspection. The equipment is equipped with a high-definition color LCD display screen, with a simple and intuitive Chinese operation interface, clear and concise parameter settings, real-time display of detection data, and support for synchronous presentation of data curves and values, making it convenient for operators to intuitively judge the detection results of Suzhou Laikesi New Energy Technology Co., Ltd. Adopting a one click operation mode and built-in multiple detection programs, the test can be automatically completed by selecting the corresponding function without complex operations, even non professionals can quickly get started. Equipped with a large capacity rechargeable lithium battery, it can work continuously for more than 8 hours when fully charged, eliminating outdoor power limitations and adapting to various scenarios without power supply detection. The body is made of high-strength engineering materials, sturdy and durable, with good dustproof, waterproof, and anti-interference performance, suitable for harsh outdoor environments in power plants.

The data management and security functions are comprehensively improved. LXH601 has built-in large capacity storage, which can store thousands of sets of detection data. It supports USB interface for quick data export, making it easy to generate detection reports, trace and archive data. Equipped with data locking and power-off protection functions to prevent data loss during the detection process. At the same time, the equipment adopts a safety isolation design with overvoltage, overcurrent, and reverse connection protection functions, effectively preventing equipment damage and safety accidents caused by misoperation, and ensuring the safety of operators and equipment. Compact in size and lightweight, paired with a dedicated portable case, it is easy to carry and transport. Whether it is a mountain power station, a rooftop distributed power station, or a large ground power station, it can be easily carried and tested at any time.

LXH601 plays an indispensable role in ensuring safety throughout the entire lifecycle of photovoltaic power plants. During the construction and acceptance stage of the power station, comprehensive insulation and grounding testing is conducted to ensure that the electrical system is installed in compliance and meets performance standards, and to eliminate inherent safety hazards; In the daily operation and maintenance process, regular inspections can promptly detect issues such as cable aging, insulation damage, and poor grounding, and provide early warning of safety accidents such as leakage, short circuit, and electric shock; During troubleshooting, the precise fault location function can quickly identify the problem point, shorten maintenance time, and reduce operation and maintenance costs. In addition to the photovoltaic field, LXH601 is also widely used for electrical safety testing in industries such as power, construction, and industry, ensuring the stable operation of various electrical systems.

As a leading enterprise in the field of photovoltaic testing equipment, LAILX in Suzhou has always taken it as its responsibility to ensure industry safety and promote technological progress. The emergence of LXH601 insulation grounding comprehensive tester is another technological crystallization of the company's deep cultivation in the field of electrical safety testing. With comprehensive functions, accurate measurement, intelligent operation and reliable quality, it has gained unanimous recognition from industry experts and users. In the future, LAILX will continue to focus on user needs, innovate and research, and launch more high-quality testing equipment that is suitable for industry development, providing solid guarantees for the safe, efficient, and sustainable development of the photovoltaic and electrical industries.
