Core functions and advantages

1. Comprehensive protection and precise control

The module is equipped with a rich library of protection functions, which can flexibly configure protection logic and settings based on the fault characteristics of different equipment such as transformers, motors, and feeders in medium and low voltage distribution systems. For example, for motor loads, inverse time overcurrent protection and locked rotor protection can be enabled to accurately match the overload characteristics of the motor; For feeder circuits, quick break overcurrent protection and ground fault protection can be configured to quickly cut off short-circuit faults. At the same time, it supports online modification and solidification of protection settings, and can complete configuration updates without power outage, ensuring the continuity of system operation. In addition, the module has a protection action recording function, which can store the last 200 protection events (including fault type, fault parameters, and action time) with a resolution of 1ms, making it easy to analyze and trace faults.

2. High precision data collection and monitoring

Using a 16 bit high-precision ADC conversion chip and advanced signal conditioning circuit, real-time acquisition of electrical parameters such as current, voltage, power, and frequency is achieved with an accuracy of ± 0.1% FS, far exceeding the industry average level (± 0.5% FS). It can calculate and monitor electric energy parameters such as active power, reactive power, apparent power, power factor, and electric energy (active/reactive). The accuracy of electric energy measurement meets the IEC 62053-22 Level 1 standard, and can replace traditional electric energy meters to achieve accurate measurement and statistics of electric energy. At the same time, it supports real-time monitoring of the module's own operating status (such as power status, communication status, I/O status). When module abnormalities (such as power failure, communication interruption) are detected, local and remote alarms can be triggered to improve system operation and maintenance efficiency.

3. Flexible communication and remote operation and maintenance

Multi protocol compatibility: fully supports the IEC 61850 standard communication protocol, seamlessly integrates with intelligent distribution automation systems, and achieves standardized transmission of protection information, measurement data, and control instructions; Simultaneously compatible with mainstream protocols such as Modbus and DNP3.0, it facilitates integration with third-party SCADA systems, PLC devices, and human-machine interfaces (HMI), reducing system integration costs

Network redundancy: equipped with dual gigabit Ethernet ports, supporting network redundancy (such as ring network redundancy, dual network redundancy). When the main communication link fails, the backup link can be switched within 100ms to ensure uninterrupted communication and meet the high reliability communication requirements of critical power distribution systems

Remote control and operation: Supports remote control (such as remote tripping/closing of circuit breakers, remote modification of protection settings), remote parameter configuration, remote firmware upgrade, and fault diagnosis through communication networks. Operation and maintenance personnel can complete more than 90% of maintenance work without the need to be on site, especially suitable for operation and maintenance management of decentralized distribution networks (such as power distribution systems in multiple buildings in industrial parks)

4. High reliability and ease of use

Hardware reliability: industrial high stability electronic components (such as military grade capacitors and anti-aging resistors) are used, and key circuits (such as power supply circuits and protective outlet circuits) are designed with dual redundancy.
