Core function: When faults occur in transformers, generators or power transmission lines (such as short circuits), it can accurately identify the fault within milliseconds (for example, the action time of differential protection ≤ 10ms) and issue a trip command to isolate the fault, preventing equipment damage and large-scale power outages.

Main features:

High-voltage dedicated protection logic: In-built differential protection, distance protection, zero-sequence protection, etc., complex algorithms specifically designed for high-voltage scenarios.

Ultra-high precision and speed: Utilizing high-precision sampling (with an error of ±0.1%) and microsecond-level synchronization technology, it ensures the accuracy of protection actions.

Communication in intelligent substations: Fully supports the IEC 61850-9-2 standard, capable of transmitting sampled values and GOOSE trip signals via optical fiber networks, meeting the requirements of digital substations.

Powerful fault recording: Built-in large-capacity fault waveform recording function, capable of recording waveform data for thousands of cycles before and after the fault, facilitating post-fault analysis.

Application fields:

It is mainly applied in substations and power plants of the power system, protecting the core primary equipment such as main transformers, high-voltage transmission lines, generators and busbars.
