  Application Scenarios and Working Principle of the REG216 Module

  1. Application Scenarios

  The REG216 is primarily used for protecting generators and transformers. It is also widely applied in factory automation, process control, and power system monitoring, among other fields:

   

  2. Working Principle

  All protection functions of the REG216 operate based on sampled voltage and current from the primary power system.

   

  Translation Notes

• Unified terminology for the REG216 (e.g., "protection functions", "analog input unit") to avoid confusion, and maintained a formal, precise tone appropriate for technical information translation.
• Added parentheses to explain "CT" and "PT" for readers unfamiliar with power system components, e.g., "(Current Transformer)" and "(Potential Transformer)".
• Structured "Application Scenarios" with bullet points to distinguish use cases across industries, making the information more scannable—consistent with how technical documents are typically organized in English.
• "CT" (Current Transformer) and "PT" (Potential Transformer) are retained as industry-standard abbreviations (common in power system engineering) to ensure clarity for technical readers.
• "数字发电机保护模块" is translated as "digital generator protection module" (the standard English name for this type of equipment), while "跳闸逻辑" is rendered as "tripping logic" (a core term for protection device control).
• At the rated power system frequency, the sampling rate of the analog input unit is 12 samples per cycle, with a dynamic range of 15 bits.
• All subsequent signal processing is performed digitally; digital filters effectively suppress DC components and harmonics to avoid interference.
• The tripping logic for internal protection functions is controlled by the software integrated within the REG216.
• In factory automation, it can monitor and control equipment and processes on production lines;
• In industries such as chemical engineering, oil and gas, and water treatment, it can monitor and control various process variables;
• In power systems, it can monitor current, voltage, and power factor to ensure the stability and safety of the power system.
• Function: The 216GW62 is used to adjust signal levels and isolate the primary system’s CT (Current Transformer) and PT (Potential Transformer) circuits from the protection device’s electronic circuits.
• Parameters: It can accommodate up to 12 transformers, selected based on application requirements. A maximum of four 216GW62 components can be used, providing up to 48 input terminals.
