In the research, testing and acceptance of new energy power equipment, short-circuit and ground fault simulation serves as a core item to verify the protection performance, withstand voltage capability and operational stability of equipment. Traditional testing devices are usually limited by incomplete phase simulation, single working conditions, scattered structure and complicated operation, making them unable to meet the full-dimensional testing requirements of charging piles, photovoltaic inverters, energy storage converters and low-voltage distribution equipment. Breaking through the limitations of conventional testing equipment, the PLB-SRD full-phase fault simulation all-in-one tester integrates comprehensive power fault simulation functions, serving as a dedicated integrated testing device for power safety standard tests, product quality inspection and laboratory research and development.
Compared with traditional split testing devices, the core advantage of the PLB-SRD all-in-one tester lies in its full-phase full-coverage fault simulation capability. It can comprehensively simulate all types of power faults, including single-phase grounding, two-phase short circuit, two-phase grounding short circuit and three-phase short circuit. Covering all common fault conditions of low-voltage distribution systems, new energy power generation systems and charging pile power supply systems, it solves the industry defect of traditional equipment that only supports single-phase testing without multi-condition switching. A single PLB-SRD device can complete the whole set of fault injection tests without auxiliary equipment, greatly simplifying the testing process.
To restore real on-site operation conditions, the PLB-SRD tester is equipped with a multi-gear adjustable current-limiting resistance module, supporting free switching between high and low impedance faults. It can accurately simulate high-impedance faults of long-distance cables and low-impedance short-circuit faults at close range. By truly reproducing fault impacts in actual operation, it precisely verifies the short-circuit protection response time, tripping accuracy, fault blocking capability and impact resistance of tested equipment. All test data fully complies with new energy industry specifications and grid connection standards.
Adopting an integrated cabinet design, the equipment features compact structure and high functional integration, effectively avoiding the messy wiring, complicated assembly and large occupation space of traditional devices. Equipped with an intelligent touch control system, it supports intuitive parameter configuration, adjustable fault duration, test interval and cycle times, and automatic batch testing. It significantly reduces manual operation difficulty and improves the efficiency of mass production sampling and laboratory testing. Meanwhile, built-in multi-protection mechanisms including overheating, overload and emergency power-off ensure full safety for operators and tested equipment, adapting to long-term and high-frequency testing scenarios.
With the continuous upgrading of testing standards in the new energy industry, full-dimensional fault simulation has become a mandatory requirement for compliant production and safe grid connection. Featuring multi-function integration, full-phase coverage, realistic working conditions and stable performance, the PLB-SRD full-phase fault simulation all-in-one tester is widely applicable to new energy manufacturers, power testing institutions, university laboratories and scientific research institutes. It provides reliable hardware support for safety performance verification and product iteration of power equipment, acting as an efficient integrated testing device in the field of new energy power detection.
