As a high-voltage direct current electrical system, photovoltaic power plants are exposed to outdoor environments for a long time, and are susceptible to erosion from rainwater, humidity, dust, and ultraviolet radiation. Problems such as aging of cable insulation layers, damage to component insulation, and corrosion failure of grounding devices occur frequently, which can easily cause safety accidents such as leakage, electric shock, short circuit, and lightning strikes. Insulation performance and grounding reliability are the core prerequisites for ensuring personnel safety and stable equipment operation. LAILX Suzhou has launched the LXH601 comprehensive insulation and grounding tester, which integrates insulation resistance testing, grounding resistance testing, fault location, and continuity testing. With 1500V high voltage testing capability, high-precision measurement, and intelligent design, it provides a one-stop detection solution for electrical safety of photovoltaic systems.

LXH601 is specially customized for photovoltaic high-voltage scenarios, supporting up to 1500VDC insulation test voltage, perfectly matching the requirements of 1500V photovoltaic systems. The insulation resistance measurement range is 0.02M Ω~2000M Ω, and the grounding resistance covers 0.01 Ω~30k Ω. It supports multiple grounding test modes such as three pole method and bipolar method, meeting the insulation and grounding detection requirements of components, strings, arrays, combiner boxes, inverters and other links. The equipment adopts advanced digital filtering and adaptive anti-interference algorithms to effectively suppress outdoor strong electromagnetic and humid environmental interference, ensuring stable and accurate data under complex working conditions. It can accurately capture subtle hidden dangers such as insulation degradation, poor grounding, and cable damage, providing scientific basis for safety warning.

Functionally, LXH601 integrates five core modes: insulation resistance testing (IR), grounding resistance testing (EARTH), insulation fault location (GFL), protective conductor continuity (RPE), polarization index (PI) testing, with one click switching, meeting the electrical safety testing requirements of photovoltaic full scene. The GFL fault location mode can accurately lock the position of insulation damage points in the string, without the need for step-by-step troubleshooting, greatly improving the efficiency of fault handling; The automatic discharge function ensures the rapid release of residual charges after testing, eliminates the risk of electric shock, and comprehensively guarantees the safety of operators. The device is equipped with a high-definition LED display screen, which displays test parameters, curves, and results in real time. It has a built-in large capacity lithium battery with a battery life of up to 8 hours, supports Bluetooth and USB data transmission, and automatically generates standardized test reports. The data can be stored, exported, and traced, achieving a closed-loop management of "detection recording warning processing".

LXH601 strictly adheres to relevant electrical safety standards such as IEC and GB, and has passed authoritative certification. It is suitable for all scenarios of photovoltaic power station construction acceptance, regular safety testing, operation and maintenance troubleshooting, third-party safety assessment, etc. It is widely used in various projects such as centralized power stations, distributed power stations, and household photovoltaics. As the core equipment for LAILX photovoltaic safety testing, LXH601 fills the market demand for high-voltage insulation and grounding integrated testing of 1500V photovoltaic systems with professional, accurate, and convenient performance. It builds a solid defense line from the source of electrical safety, effectively avoids safety accidents, ensures long-term stable operation of power stations, and promotes the standardization and intelligent upgrading of safety testing in the photovoltaic industry.
