The core technical highlight of this device is the specialized DC voltage adaptation range of 0-1500V, which can adapt to the high-voltage DC cable environment of large-scale photovoltaic power stations. It supports the detection of DC arc faults, which is a common hidden fault in photovoltaic systems, and can effectively avoid potential safety hazards caused by arc faults. It adopts a lightweight design with a host weight of only 1.0kg, which is convenient for maintenance personnel to carry around in the photovoltaic power station. The built-in Bluetooth 5.0 module can synchronize test data to the photovoltaic power station management platform, facilitating unified management of cable fault information.
The host dimensions are 200mm × 110mm × 55mm, with a host weight of 1.0kg (including battery). The detection distance ranges from 0 to 10km, with a fault positioning accuracy of ±1m. It is specially designed for photovoltaic DC cables, supporting the detection of various types of photovoltaic cables including PV1-F cables. The operating voltage range is DC 0-1500V, with a charging specification of 5V/2A. The storage temperature ranges from -20℃ to 55℃, with a 4.3-inch TFT color screen, a signal sampling frequency of 90MHz, a protection rating of IP54, and supports DC arc fault detection function.
This tester is mainly applicable to large-scale ground photovoltaic power station maintenance, distributed photovoltaic household system cable testing, photovoltaic engineering acceptance, photovoltaic equipment maintenance and other scenarios. It can accurately locate various faults of photovoltaic DC cables, including open circuit, short circuit and DC arc faults, ensuring the safe and stable operation of photovoltaic power generation systems, and meeting the testing needs of photovoltaic industry maintenance personnel.
