The REF545KB133AAAA is a feeder protection device or feeder protection measurement and control device manufactured by ABB. The feeder protection device is an important device in the power system, which is mainly used to quickly remove the fault part when the feeder (that is, the transmission line) has short circuit, ground fault or other abnormal conditions, so as to protect the stable operation of the power system.

The device can sense abnormal current and voltage signals in the power system and compare them with pre-set fail-safe conditions. Once a fault is detected, it quickly cuts off the fault link and prevents the fault from spreading throughout the grid. This helps to reduce the impact of faults on the power system and ensure the continuity and stability of the power supply.

The REF545KB133AAAA works on the basis of current and voltage sensors mounted on the feeder. These sensors can detect, measure and process fault signals for fault judgment and rapid removal. The device adopts digital signal processing technology, which can detect feeder fault quickly and accurately, and realize fast cutting, and further ensure the safe and stable operation of power system.

In general, REF545KB133AAAA is an important part of the power system, which is of great significance to improve the reliability, stability and safety of the power system. By quickly and accurately detecting and removing feeder faults, it helps reduce outage times, reduce the risk of equipment damage, and ensure continuity of power supply.
