DTDS End-User Power Protection and Management System

Product Introduction:

The End-Point Power Protection and Management System (DTDS) is an intelligent system designed for comprehensive management, protection, and detection of end-point electrical circuits. Utilizing the latest hardware architecture and control systems, it features powerful data analysis and real-time tracking capabilities. It can quickly compensate for voltage surges or sags, fluctuations in the end-point power supply system, and control the current distribution at the end-point. Based on the characteristics of end-point electrical equipment, it provides real-time voltage protection, current protection, and non-electrical protection for end-point switching devices. According to system settings, it uses audible and visual alarms and communication to guide maintenance personnel in quickly identifying and promptly addressing issues.

Functional Overview:

The End-Point Power Protection and Management System detects and analyzes the current in end-point circuits. Following the principles of power supply continuity and safety, it manages harmonics and three-phase imbalances, protects precision equipment, eliminates neutral line current, and provides overcurrent protection for the neutral line after management, including time-delay and inverse-time protection.

Overcurrent damage to the neutral line leading to "neutral break" is a very serious electrical fault. Moreover, once the neutral line is damaged, not only does the system failure caused by the neutral break become severe, but replacing the neutral cable is also very troublesome. Therefore, the terminal has established a more comprehensive protection scheme for the neutral line. Under normal operating conditions, the terminal only functions to eliminate neutral line current and monitor the operational status of the neutral line. In extreme cases, based on settings, the terminal allows short-term overcurrent and overheating of the neutral line, issuing alarm signals to enable technicians to promptly diagnose and resolve faults. If the alarm cannot be cleared and the neutral line overcurrent or overheating limits are reached, to protect the neutral line, the terminal will decisively output a trip signal, disconnecting the phase line of the branch circuit switch to halt operation. This ensures both the continuity of power supply and maximum protection of the neutral line.
