The DTU Intelligent Electrical Control Cabinet is an automated control device designed for power distribution systems. It integrates data acquisition, remote monitoring, fault protection, and communication management into a single unit. Featuring a modular design and customizable configurations, it. In order to solve the problems such as insufficient perception ability of distribution equipment, low level of intelligence, and difficulty in accessing distribution automation system, this paper proposes a new distributed intelligent distribution ring network cabinet based on system on chip. The ZT-D30 Distribution Automation Substation Terminal DTU is primarily applied in distribution automation systems. It is installed in locations such as 10KV ring main units, sub-section posts, electricity distribution rooms, switch rooms, comprehensive rooms and so on. The product has strong stability, high reliability, good real-time performance, and strong environmental adaptability. The control room is considered one of the most critical areas in any facility, impacting daily decision-making and overall. Managing and installing a rack power distribution unit (PDU) has never been easier than with the EL2P PDU.
