Exploring New Pathways in Electrical Testing Together: A Delegation from Baoding, Hebei Visits Goldhome for Inspection and Exchange
Recently, a delegation from Baoding, Hebei Province, made a special visit to Goldhomefor an inspection and exchange. This visit focused on collaboration regarding core equipment within the power testing sector, with particular emphasis on the company's flagship product-the GIS Partial Discharge-Free Fault Simulation Device. The delegation gained an in-depth understanding of the product's performance, operational procedures, and application value, while also discussing potential future cooperation. Goldhome's relevant personnel and technical team extended a warm welcome and provided professional services throughout the visit. They accompanied the delegation during discussions, product inspections, and practical demonstrations, comprehensively showcasing the company's capabilities and service standards. This earned high recognition from the visitors and laid a solid foundation for deepening future collaboration and achieving mutual benefits.
Upon arrival at Goldhome, the delegation first engaged in discussions with relevant company representatives. During the meeting, company officials provided a detailed overview of Goldhome's development history, product portfolio, technological R&D capabilities, and industry application cases. They specifically addressed the practical requirements for power system construction and GIS equipment operation and maintenance in Baoding, Hebei Province, highlighting the core adaptability and application effectiveness of the GIS Partial Discharge-Free Fault Simulation Device. Addressing their operational challenges, the delegation inquired in detail about the product's technical specifications, customisation capabilities, after-sales support, and cooperation models. Both parties engaged in in-depth discussions on application scenarios for power testing equipment and technical upgrade directions, reaching preliminary consensus on collaboration. This laid a solid foundation for subsequent on-site product inspections.
Technical engineers conducted on-site operational demonstrations, fully presenting the complete testing process of the GIS partial discharge-free fault simulation device. Members of the client delegation observed attentively, took detailed notes, and raised questions periodically, to which the engineers provided patient and thorough responses. The specific testing procedure comprised four steps: Step One: Preliminary Preparation Verify the device's power supply and wiring connections are normal, ensuring all connections are secure and free from looseness. Simultaneously, check the SF6 gas pressure in the gas chamber (factory standard: 0.4 MPa) and confirm the gas leakage rate meets requirements. Clear any debris around the device and implement safety precautions. Step Two: Parameter configuration. Based on testing requirements, core parameters such as rated voltage and test duration are set via the control panel. The corresponding discharge type is selected, allowing flexible adjustment of the discharge signal's initial voltage, extinction voltage, and discharge intensity. Step Three: Initiate Testing. Upon activation, the high-voltage partial discharge-free transformer supplies stable high voltage. The apparatus automatically simulates common discharge faults within GIS equipment, including tip, air gap, particle, and surface discharges. Multiple discharge types may occur concurrently. Simultaneously, ultra-high-frequency probes capture discharge signals, displaying critical data such as discharge quantity, current, and voltage in real time. Step Four: Analysis and Conclusion. Upon test completion, the apparatus automatically generates a detailed test report for saving and printing, facilitating subsequent data collation and analysis. Post-testing procedures include gradually reducing the high voltage, switching off the power supply, disconnecting all wiring, and properly stowing equipment and cables to conclude the entire testing process.
The company specialises in the R&D, production, and sales of high-voltage electrical testing equipment. In 2021, it acquired Wuhan San Gao Electrical Testing Equipment Co., Ltd. in a wholly-owned merger.
