Goldhome Launches New 200kA Surge Current Generator to Enhance Lightning Protection Testing for High-Voltage Equipment
Recently, Wuhan Goldhome Hipot Electrical Co., Ltd. (Goldhome) introduced its new 200kA surge current generator. With core advantages including high current output, adaptability to multiple scenarios, and high reliability, the device provides an efficient solution for lightning protection testing of power equipment. As a high-tech enterprise specializing in the R&D and production of high-voltage testing equipment, Goldhome has been deeply rooted in the industry for nearly two decades. Focusing on breakthroughs in core technologies for surge current and surge voltage equipment, the company possesses an in-house R&D center and a comprehensive production and testing system, enabling it to provide customized testing solutions. This new product, built on proprietary technology, breaks through the limitations of traditional equipment and demonstrates the company's innovative capabilities in the field of high-current testing.
The device boasts outstanding core advantages, with a rated surge current of 200 kA as its key performance indicator. It can precisely output various standard surge current waveforms, including 4/10 μs and 8/20 μs, while also supporting simulation of 10/350 μs direct lightning strike waveforms. The waveform parameter adjustment accuracy reaches ±1.5%, fully complying with international and domestic standards such as IEC 61000-4-5 and GB/T 17626.5, and other international and domestic standards. It is suitable for impulse withstand testing of various devices, including surge arresters, SPDs (Surge Protection Devices), and grounding systems, addressing the pain points of traditional equipment such as limited waveform variety and insufficient accuracy.
The device adopts Goldhome's proprietary compact modular design, combined with 3D electric field optimization technology, reducing its volume by 40% compared to devices of the same performance level. This facilitates both permanent laboratory installation and transportation for temporary outdoor operations. Equipped with a hybrid system of electronic switches and pneumatic triggers, it achieves a trigger response time of <5 μs and excellent synchronization performance. Capable of continuous and stable operation, it can complete a rated current test every 40 seconds, improving testing efficiency by 60% compared to traditional equipment and significantly reducing testing time.
The equipment excels in both safety and durability. Each main capacitor bushing is equipped with a high-energy, non-inductive energy-absorbing resistor in series, complemented by multi-level interlock protection and an automatic grounding mechanism, ensuring comprehensive testing safety and rapid fault protection response. Utilizing high-quality, high-voltage-resistant components and epoxy insulation technology, the system contains no redundant or vulnerable parts, reducing annual maintenance costs by 45% and extending the service life to over 20 years. Backed by Goldhome's comprehensive after-sales support system, the equipment offers remote guidance and on-site operation and maintenance support, further enhancing the user experience and enabling efficient completion of quality spot checks and type tests in the power and new energy sectors.
