3. Product Features
3.1 Core Protection Functions
Transformer Differential Protection (87T): Equipped with fast low-impedance differential protection function. It can automatically match CT ratios and compensate vector groups, applicable to multi-circuit breaker configurations with up to six restrained CT inputs. The differential protection integrates second harmonic and waveform blocking functions to avoid false tripping caused by CT saturation and transformer inrush current; it also adopts fifth harmonic blocking logic to prevent tripping triggered by transformer over-excitation.
Overcurrent Protection: Supports definite-time and inverse-time overcurrent protection, covering three-stage overcurrent protection, negative-sequence overcurrent protection and other sub-functions.
Earth Fault Protection: Built with low-impedance earth fault protection (REFPDIF) and high-sensitivity zero-sequence current protection.
Distance Protection: Supports three-stage distance protection, directional impedance elements and Mho impedance supervision logic.
Voltage & Frequency Protection: Realizes overvoltage, undervoltage, over-frequency and under-frequency protection functions.
Over-excitation Protection: Provides real-time monitoring and protection against transformer over-excitation faults.
3.2 Other Technical Advantages
- Stable operation within a wide frequency range to adapt to frequency fluctuation of power systems
- Low requirements for main CT, no intermediate CT required for field wiring
- Built-in disturbance recorder and event recorder to facilitate post-fault analysis and troubleshooting
- Powerful self-diagnosis function to monitor real-time operating status of internal modules
- Supports local and remote control, with built-in safety interlock function
- Pluggable modular design for convenient on-site installation, replacement and maintenance
4. Structure & Composition
4.1 Hardware Structure
