Against the backdrop of global energy transition and industrial upgrading, professional and accurate testing services have become an important support for the high-quality development of the energy and power industry. The customer in this cooperation is a professional and independent testing and research institute focusing on the energy and power sector. With years of deep roots in the industry, it boasts advanced laboratory facilities, a strict quality management system and a high-caliber professional technical team. It provides users in power generation, transmission, new energy, power equipment and other related industries with a full-chain service covering testing, certification, technical consulting and R&D support. Adhering to international standards and industry norms, it delivers accurate, impartial and efficient technical services to global customers, making it a core partner for enterprises across the entire energy and power industry chain.
As its business continues to expand, the institute urgently needs to introduce a batch of high-performance professional testing equipment to further enhance its testing capabilities, expand its service scope, better meet the testing needs of various customers, help enterprise customers improve product performance, ensure operational safety, comply with regulatory requirements and strengthen market competitiveness. After extensive research, rigorous comparison and screening, the institute finally chose to cooperate with LISUN. Its core demands focus on integrating sphere systems and EMC-related testing equipment, specifically including surge generators, fast transient burst generators and EMI conducted and radiated interference test systems.
Upon receiving the customer’s requirements, LISUN attached great importance and formed a professional technical team to conduct in-depth communication on the customer’s actual testing scenarios and applicable international standards, and fully analyze the customer’s pain points and core demands in testing. Considering the institute’s professional positioning in energy and power testing and its stringent requirements for equipment accuracy and stability, we recommended a tailored series of products for the customer.
The integrating sphere system adopts LISUN LPCE-2(LMS-9000) High Precision Spectroradiometer Integrating Sphere System. Paired with relevant accessories, it forms a complete integrated test system for optical, color and electrical parameters. Featuring high uniformity and high reflectivity, it can accurately perform tests related to optical radiation characteristics, meeting the optical parameter testing requirements of energy equipment, and is also one of LISUN’s core competitive products.
The EMC series equipment precisely matches customer needs, with the recommended SG61000-5SA Surge Generator, EFT61000-4 EFT Immunity Measurement and the supporting EMI-9KA EMI Receiver Test System. The SG61000-5SA fully complies with IEC61000-4-5, and the EFT61000-4 meets the testing requirements of IEC61000-4-4. The complete set of EMC equipment covers EMC immunity and interference tests, perfectly conforming to domestic and international standards such as IEC 61000 and GB/T 17626, providing strong support for equipment reliability verification.
During the cooperation, the technical team maintained efficient communication with the customer, repeatedly confirmed equipment parameters, testing standards and application scenarios, accurately resolved various questions raised by the customer, and continuously optimized the scheme details. Finally, the solution was highly recognized by the customer and the order was successfully placed.
After receiving the payment, LISUN immediately launched the production process, strictly controlled production quality to ensure equipment performance and timely delivery. Upon delivery of the equipment, we provided detailed operation manuals, professional operation videos, and arranged an after-sales team to provide full online support. We patiently guided the customer through equipment installation, commissioning and operation training, helping the customer quickly master operation skills and put the equipment into testing work smoothly.
