WXH-830D series microcomputer line protection and measurement device
The WXH-830D product is the latest HELLO series product launched by Xuji. It is a high-quality and cost-effective integrated protection, measurement and control device provided by Xuji based on decades of successful experience in the manufacturing of secondary equipment in the power system. WXH-830D is suitable as a protection and measurement device for power lines with voltage levels of 66 kV and below.

H. The quality of E, L, L, and O is a common feature of Xuji HELLO series products, as follows:
H: High, high quality includes:
High tech: Adopting on-site configuration technology (FCT) and visual software development technology (VLD).
High quality: Based on professional and mature software and hardware platforms, rich operating experience and fully validated principle algorithms, automatic testing as the premise, advanced R&D management concepts and R&D management tools as the means, to ensure the quality of each link in the R&D, production, and manufacturing processes, and provide users with high-quality products.
E: Easy, easy work includes:
Easy to use: With a user-friendly interface and a Windows like operation menu, it features a debugging guide system and a one click calibration function, making on-site debugging, maintenance, and calibration work easy.
L: Low, low consumption includes:
Low input cost: Different devices share plugins, reducing the cost of purchasing devices and spare parts reserves.
Low failure rate: Advanced detection technology and a comprehensive production quality assurance system greatly reduce product failures and greatly reduce the downtime of protected objects.
L: ReaLize, the implementation technology includes:
Platformization: The design of software and hardware adopts a platform based approach, allowing protection devices of different voltage levels to share hardware platforms, and different hardware platforms to share software, reducing the need for future hardware and software upgrades and maintenance work.
Specialization: Research and development work in different fields is completed by professionals, integrating research and development achievements from different levels and fields through standardized interfaces, allowing users to fully enjoy high-tech products.
Modularization: Encapsulate all functional modules into flexible relays, and configure different flexible relays for different devices to complete their functions, enabling them to quickly respond to personalized needs of different users.
O: TechOlogy, patented technology includes:
VLD development technology: The VLD development tool is similar to a "PLC" development environment, in which all protection logic is composed of different visualized flexible relays, realizing the industry's dream of developing programs using relay protection languages.
Dual connector technology: Adopting the technology of rear plug-in dual connectors, the principle of complete separation of strong and weak electricity improves the electromagnetic compatibility of the device hardware.
