Feeder protection measurement and control device is an important protection equipment in the power system, REF615 is mainly used to quickly remove the fault when the feeder occurs short circuit, ground fault or other abnormal conditions, to protect the stable operation of the power system.

The feeder protection measurement and control device can sense the abnormal current and voltage signal in the power system and compare it with the preset fault protection conditions. When the fault is detected, it can quickly cut off the fault link and prevent the fault from spreading to the power grid.

In addition, the feeder protection measurement and control device also has a variety of other functions, such as instantaneous electrical flow rate break, limited time electrical flow rate break, fixed time over current, over load, low frequency load reduction, three-phase voltage detection and non-reclosing, control loop break alarm.

In short, the feeder protection and control device plays an important role in the power system, which can ensure the stable operation of the power grid and the safety and reliability of the power supply.

In addition to the above main functions such as rapid fault removal and stable operation of the power system, the feeder protection measurement and control device also has the following uses:

Fault location: The feeder protection measurement and control device can quickly and accurately locate the fault section by analyzing the current and voltage signals during the fault, which provides important information for rapid fault processing.

Fault type identification: The feeder protection measurement and control device can identify different types of faults, such as short circuit, ground fault, broken line, etc., which helps to deal with the fault.

Communication function: The feeder protection measurement and control device has the ability to communicate with other devices, and can receive scheduling instructions, send fault information, real-time monitoring data, etc., to realize the intelligent management of the power grid.

Automatic reclosing: The feeder protection measurement and control device can realize the automatic reclosing function, that is, after the fault occurs, automatically disconnect and re-close the circuit breaker to try to restore power supply. This helps to improve the reliability of the power supply.

Load management: The feeder protection measurement and control device can monitor the change of load, early warning or adjustment of overload or light load to ensure the load balance and stability of the power grid.

Off-limit alarm: When the current, voltage and other parameters exceed the set value, the feeder protection measurement and control device can send out the off-limit alarm signal to remind the operation and maintenance personnel to deal with it in time.

Backup automatic power supply function: When the backup power supply is normal, the feeder protection measurement and control device can automatically input backup power to improve power supply reliability.

In summary, REF615 feeder protection measurement and control device has a variety of uses in the power system, not only can quickly remove the fault, protect the stable operation of the power system, but also can achieve fault location, fault type identification, communication, automatic reclosing, load management, off-limit alarm and backup and self-casting functions. The realization of these functions is helpful to ensure the stable operation of the power grid and the safety and reliability of the power supply.
