ABB's REM545 AG228AAAA is a microcomputer protection device whose protection scope typically covers multiple aspects to ensure the stable operation of the power system and the safety of the equipment. Here are some of the protective functions that the protective relay may have:
Overload protection: Detects the overload of the line or equipment and cuts off the power when the rating is exceeded to prevent overheating or damage to the equipment.
Short-circuit protection: When an abnormal increase in current is detected, the faulty circuit is quickly cut off to prevent short-circuit damage to the equipment and system.
Grounding protection: Monitor the grounding fault of the line, cut off the fault current in time, and protect the safety of equipment and personnel.
Undervoltage and overvoltage protection: Detect abnormal changes in voltage and take action when the voltage is too low or too high to protect equipment from damage.
Reverse power protection: When the reverse power of the generator is detected, the power supply is cut off in time to prevent damage to the generator.
Frequency protection: Monitor the frequency change of the power system, and take corresponding protective measures when the frequency exceeds the allowable range.
