Australian Clients Visit Goldhome for an In-Depth Inspection of High-Voltage Series Resonance and Mobile GTU Power Frequency Withstand Test Equipment
On June 5, a delegation of clients from the Australian power testing industry traveled a long distance to visit Goldhome's headquarters for an on-site inspection and technical exchange. During the visit, the clients focused on inspecting the company's independently developed high-voltage series resonant test equipment and mobile GTU power frequency withstand voltage test equipment, and they highly praised the equipment's outstanding performance, innovative design, and on-site application capabilities. This exchange further solidified the foundation for cooperation between Goldhome and the Australian market, instilling strong confidence in the implementation of future projects.
- Focusing on Core Equipment, Witnessing Goldhome's Technical Strength
Accompanied by Goldhome's technical lead and international business team, the Australian clients first visited the high-voltage testing equipment exhibition area. They expressed keen interest in Goldhome's high-voltage series resonant testing equipment. This equipment employs a variable-frequency series resonant topology, offering significant advantages such as automatic tuning, high quality factor, and low input capacitance. It is widely applicable for power frequency AC withstand voltage testing of high-capacitance test specimens, including GIS, cables, generators, and transformers. Technical staff conducted an on-site demonstration of the equipment's full testing process, including automatic frequency scanning, resonance matching, and voltage ramp-up. The clients repeatedly nodded in approval of the equipment's sine waveform quality, tuning speed, and partial discharge control performance during the test.
Subsequently, the clients moved to the vehicle-mounted GTU power frequency withstand voltage testing equipment. This equipment integrates a power frequency withstand voltage test system onto a specialized vehicle chassis, delivering "mobile laboratory"-style high-voltage testing capabilities. It is particularly well-suited for mobile testing needs in field operations, wind farms, photovoltaic power stations, and substations. The client carefully inspected the vehicle layout, grounding protection system, control cabin, and high-voltage output interfaces, and raised specific concerns regarding the equipment's environmental adaptability across Australia's vast terrain (high temperatures, wind and sand, and long-distance transportation). Goldhome engineers addressed each concern individually and presented data demonstrating that the equipment had passed multiple rigorous environmental validation tests.
- On-site Testing: Let the Data Speak
To provide the client with a more intuitive experience, the Goldhome technical team conducted rapid withstand voltage tests on-site using a section of actual cable as the test specimen, employing both the high-voltage series resonance equipment and the vehicle-mounted GTU equipment. The series resonance equipment completed frequency locking within seconds, with the voltage rising steadily to the set value. The resonance quality factor (Q) reached over 40, and the current on the power supply side was less than one-thirtieth of the current on the output side. The client was amazed by this energy-saving effect. Meanwhile, the mobile GTU demonstrated its "plug-and-play" convenience-once the vehicle was positioned, grounded, and powered on with a single button, the entire process from equipment setup to voltage withstand testing was completed within 10 minutes. The client's technical lead remarked, "This kind of mobile testing capability is exactly what we urgently need for our projects in remote areas of Australia."
- Deepening Cooperation to Jointly Expand the Australian Market
During the subsequent technical symposium, both parties engaged in in-depth discussions on topics including Australian grid standards (AS/NZS), specific on-site testing requirements, remote technical support, and spare parts supply. Goldhome's head of international business stated: "Australia is a key market for high-end power testing equipment, where customers have extremely high expectations for quality, safety, and service responsiveness. This on-site visit allowed our Australian clients to experience firsthand Goldhome's R&D and manufacturing capabilities, as well as our end-to-end service capabilities. We deeply value this trust and will fully support our clients' local project implementations in the future."
In his concluding remarks, the client representative said: "We had previously gained an understanding of Goldhome through online meetings and product materials, but seeing the equipment in operation and operating the control interface firsthand is a completely different experience. Goldhome's high-voltage series resonant equipment and vehicle-mounted GTU equipment are fully comparable in performance to leading international brands, and in some aspects even offer advantages. We have a clear intention to purchase and look forward to establishing a long-term strategic partnership with Goldhome."
- Building Bridges Through Quality, Serving the World
This visit by the Australian client marks a significant milestone in Goldhome's expansion into the Oceania market. The company remains committed to being driven by technological innovation and guided by customer needs, continuously introducing high-voltage testing solutions tailored to diverse scenarios. Moving forward, Goldhome will continue to welcome global partners to visit and collaborate, working together to advance power testing technology toward greater efficiency, intelligence, and convenience.
