The GPU-3 integrates generator protection and synchronization. Serial port can be provided to communicate with PLC, SCADA system and other systems. At the same time, all three-phase measurement values and alarm information can be displayed on the LCD display.
DEIF's GPU-3 is a parallel protection device for generator protection and synchronization functions. It integrates generator protection and synchronization functions, and can provide a serial port to communicate with PLC, SCADA, and other systems. The device contains all the required three-phase measurement circuits and displays all measurement values and alarm information on a high-quality LCD screen.
In addition, DEIF's GPU-3 has an optional engine interface card with a separate power supply and microprocessor that turns the GPU-3 into an engine control unit with start/stop and protection functions. If the GPU-3 processor fails, the engine interface card goes into standby mode to avoid interruption of the engine monitoring function. If the stop alarm occurs, the engine will automatically stop. DEIF's GPU-3 is therefore a reliable solution for controlling and monitoring Marine generator sets.
DEIF GPU-3 also has a variety of protection functions, including overcurrent protection, voltage protection, frequency protection, busbar voltage protection, busbar frequency protection, main grid fault protection, overload protection, current imbalance protection, voltage imbalance protection, reactive power input (lost excitation) protection, reactive power output (overexcitation) protection. In addition, it also has directional overcurrent protection, bus unbalanced voltage, time undervoltage, reactive power determined according to power, non-important load tripping (unloading), undervoltage and reactive power low, generator switch external tripping, synchronization and switch alarm, bus switch position fault, regulation alarm, load distribution monitoring and other functions.
In summary, DEIF's GPU-3 is a powerful, flexible and reliable generator protection and synchronization device for a variety of applications where precise control and management of generator sets are required.

DEIF's GPU-3 is a generator protection and synchronization device with a variety of functions, including:
Parallel protection function: The GPU-3 can monitor and protect generators operating in parallel to ensure current sharing and stable operation between them.
Generator protection: GPU-3 provides comprehensive generator protection, including overcurrent, undervoltage, overvoltage, frequency deviation, reverse power, etc., to protect the generator from damage.
Synchronization function: GPU-3 has an automatic synchronization function, which can automatically synchronize the generator set to be connected with the power grid and put it into operation. At the same time, it can also monitor the voltage, frequency and phase of the power grid to ensure the smooth grid connection of the generator set.
Measurement and display functions: GPU-3 has a variety of measurement functions, which can monitor the voltage, current, frequency, power and other parameters of the generator set in real time, and display these parameters and alarm information on a high-quality LCD screen.
Communication function: GPU-3 provides serial communication function, and can exchange data and remote monitoring with PLC, SCADA and other systems, which is convenient for users to monitor and manage the generator set.
Engine control function (optional) : With an optional engine interface card, the GPU-3 can be transformed into an engine control unit with start/stop and protection functions for full control and monitoring of the engine.
In summary, DEIF's GPU-3 has a variety of features to meet the full range of user needs for generator set control and protection, and is an efficient, reliable and easy-to-use solution.
