REF545KB133AAAA FEEDER TERMINAL protection device
The REF545KB133AAAA feeder terminal has a variety of functions. First, it is able to monitor the electrical parameters on the feeder, such as voltage, current, power factor, electrical energy, etc., and provide remote control functions such as switching operation, fault isolation, etc. Secondly, the feeder terminal has built in a variety of protection functions, such as overload protection, short circuit protection, ground fault protection, etc., to protect the electrical equipment and lines on the feeder from damage. In addition, it also has a communication function that can communicate with upper-level management systems (such as energy management systems, building automation systems) to achieve remote monitoring and data acquisition.
The protection functions also support different types of networks, such as, isolated neutral networks, resonant-earthed networks and partially earthed networks. The application area also covers medium-sized three phase asynchronous motors as well as protection and control of shunt capacitor banks used for reactive power compensation. In addition to protection, measurement, control, condition monitoring and general functions, the REF 541 feeder terminals are provided with a large amount of PLC functions, which allow for several automation and sequence logic functions, needed for substation automation, to be integrated into one unit.
