GE DPU. 1 slot rack
Product manual:
GE DPU (Digital Protection Unit) is a high-performance digital relay protection device commonly used in transmission and distribution systems, substation automation, and industrial power protection. The DPU 1 slot rack (single slot rack) version is typically used for compact protection systems, providing basic to advanced relay protection, event recording, remote communication, and other functions.
Main features of GE DPU 1 slot rack
2. Relay protection function
Instantaneous&Time Overcurrent Protection: Quickly detect and remove faults to prevent equipment damage.
Overvoltage/undervoltage protection: Monitor abnormal voltage to prevent abnormal equipment operation.
Frequency protection: Suitable for unstable power grid scenarios, preventing system crashes due to frequency offset.
Directional Protection: detects short circuits or current direction, enhances selective tripping capability.
Differential Protection (supported by some models): monitors internal faults in equipment and improves fault detection sensitivity.
3. Event recording and data analysis
SOE (Sequence of Events) event recording: Accurately record the sequence of relay operations for easy fault analysis.
Fault waveform capture: Record current and voltage waveforms, support external software analysis.
Remote monitoring: Status monitoring and data transmission can be carried out through SCADA or other systems.
4. Communication interface
RS-232/RS-485 serial communication: supports protocols such as Modbus and DNP3, suitable for remote monitoring.
Ethernet (some models): Supports TCP/IP protocol and can be integrated into modern power automation systems.
IEC 61850 (partial models): Complies with smart substation standards and improves interoperability.
5. Application Fields
Relay protection for distribution network (medium/low voltage system)
Substation protection and control
Industrial power systems (such as manufacturing, power smelting, petrochemicals, etc.)
Wind power, photovoltaic and other new energy grid connection protection
Common GE DPU models
DPU2000R: Classic model, suitable for power distribution protection, supports Modbus and DNP3 communication protocols.
DPU1500: A more compact version suitable for smaller systems.
