In the R&D and quality inspection processes of power systems, new energy EV chargers and power distribution equipment, accurate simulation testing of short circuit and grounding faults serves as the core key to verifying equipment protection performance and ensuring the safe operation of power grids. Traditional testing devices feature single fault modes and incomplete working condition simulation, failing to cover complex on-site fault scenarios. In contrast, the PLB-SRD Short Circuit Fault Simulator perfectly addresses industry testing pain points with full fault coverage and rigorous testing performance, emerging as a core device for reliability detection of power equipment.
The device’s premier core advantage lies in its full coverage of all types of fault working conditions. It can accurately simulate various common power faults including three-phase short circuit, single-phase grounding, two-phase short circuit and two-phase grounding, completely breaking the limitations of traditional testing instruments. It enables one-stop fault recurrence for daily operation and maintenance inspection of distribution lines, as well as factory calibration of EV chargers and power protection devices, eliminating the need for multiple devices and greatly improving testing efficiency. Supporting multi-position fault point switching, it can simulate grounding and short circuit faults at different cable positions to restore real on-site fault scenarios and ensure highly practical and authentic test data.
The PLB-SRD Fault Simulator delivers outstanding testing accuracy and flexibility. Each short circuit loop is equipped with three adjustable current-limiting resistance gears of 1Ω, 5Ω and 10Ω, allowing flexible fault impedance adjustment to precisely meet the testing standards of low-voltage power distribution, new energy equipment and other scenarios. Equipped with an intelligent programmable control system, it supports customized fault duration and trigger modes to realize automated and repetitive testing. This effectively avoids manual operation errors, ensures stable and accurate test results, and meets diverse testing requirements for R&D debugging, type tests and factory sampling inspections.
Beyond superior core performance, the device integrates reliable safety protection and user-friendly operability. It is built with multiple protection mechanisms including overheating protection, overload protection and emergency power-off function, which can automatically cut off the circuit in case of overload or overtemperature, eliminating potential safety hazards and protecting both operators and equipment. With low operating noise and standardized inlet and outlet wiring design, it is highly adaptable to various working environments such as laboratories, quality inspection workshops and on-site operation and maintenance sites.
Widely applied in new energy EV charger testing, power distribution system commissioning, electrical switchgear calibration, railway power operation and maintenance and many other fields, the PLB-SRD Short Circuit Fault Simulator accurately verifies core performances of power equipment including fault response, protection tripping and overload resistance. With the superior strengths of full fault coverage, high-precision simulation and stable safety performance, it builds a solid technical barrier for power equipment quality control and stable power grid operation, making it a preferred device for reliability testing in the power industry.
