Accurately Reproducing High-Current Lightning Surges-Goldhome Hipot 100kA Surge Current Generator for Evaluating the Performance of Lightning Protection Devices
In the quality assessment of core lightning protection components-such as zinc oxide varistor discs, surge protection devices (SPDs), and varistors-simulating the high-current transient surges generated by actual lightning strikes is a critical step in testing their current-carrying capacity and residual voltage characteristics. The 100kA impulse current generator launched by Wuhan Goldhome Hipot Electric Co., Ltd. features a peak output current of 100kA, a comprehensive multi-waveform matrix, and a fully intelligent measurement and control platform, providing a rigorous "high-current lightning strike test" for various lightning protection products and low-voltage electrical equipment.
This 100kA surge current generator offers four core product advantages.
First, a comprehensive test matrix with multi-waveform coverage. The device can stably output 8/20μs lightning surge currents (peaking at 100kA), 4/10μs high-current surge waves (peaking at 100kA), 10/350μs direct lightning strike simulation waves (peak up to 50kA), as well as 1/20μs steep-front waves, 30/80μs operating waves, 2000μs square waves, and other standard waveforms. Its technical specifications meet the requirements of GB 18802.1, IEC 61643-11, and other domestic and international standards. A single unit covers multiple testing scenarios, including surge arrester current-carrying capacity testing, SPD operational load testing, and varistor surge aging testing.
Second, a compact and efficient structural design. The product features a small footprint, compact structure, and convenient waveform adjustment. While ensuring the output of an ultra-high current of 100 kA for the 4/10 μs waveform, it achieves an optimized internal structure and component layout, significantly saving laboratory space. High-energy, non-inductive energy-absorbing resistors are connected in series on each main capacitor bushing, effectively absorbing the reverse peak energy in the discharge circuit, ensuring the safe operation of the main capacitors and extending the service life of the equipment.
Third, a fully intelligent integrated measurement and control system. The system employs integrated computer-controlled constant-current charging technology, offering a high degree of automation and strong interference resistance. Fiber-optic communication is used between the measurement and control console and the high-voltage electrical control cabinet to achieve electrical isolation between the high- and low-voltage sides. The measurement software features automatic data acquisition, automatic waveform generation, and real-time calculation of waveform characteristic parameters (T1, T2, Ipeak, etc.). Test data and waveforms are automatically saved, facilitating easy export and analysis, which significantly reduces operational complexity and the likelihood of human error.
Fourth, a multi-layered safety protection system. The equipment incorporates safety mechanisms compliant with CE standards, including built-in safety interlocks, emergency stop switches, and zero-voltage ramp-up functions. The control console is equipped with an emergency stop button, allowing the test power supply to be cut off with a single press in case of an emergency. A comprehensive grounding system and optical isolation design ensure that operators remain within a safe zone at all times.
As the R&D and manufacturing company behind this equipment, Wuhan Goldhome Hipot Electrical Co., Ltd. was established in 2008 and is located in the Wuhan Economic and Technological Development Zone. It is a national high-tech enterprise and a specialized "Little Giant" enterprise that integrates R&D, production, sales, and service. The company operates a 10,000-square-meter modern factory and employs a 51-member professional technical team. In 2021, it acquired Wuhan Sanhao Electric, a company with over 30 years of experience in manufacturing oil-free partial discharge testing equipment for ultra-high voltage applications. Goldhome maintains close collaborations with research institutions such as the State Grid Electric Power Research Institute and the School of Electrical Engineering at Wuhan University. The company holds 35 national patents and over 10 software copyrights, Our products are exported to over 30 countries and regions, including Germany, the United States, and Vietnam. With its multi-waveform coverage, intelligent, and highly safe impulse current test systems, Goldhome continues to provide robust technical support for the current-carrying capacity testing of lightning protection devices worldwide.
