Transformer Terminal
Technical Reference Manual, General
RET 54_
By means of the graphic HMI display, the control functions in the transformer
terminal indicate the position of disconnectors, circuit breakers and tap changer
locally. Local control of these objects is possible via the push buttons on the front
panel of the transformer terminal. Furthermore, the transformer terminal allows
position information of the objects to be transmitted to the remote control system.
Controllable objects, such as CBs, can also be opened and closed over the remote
control system
.

Fig. 4.1.-2
A distributed protection and control system based on REF 54_ feeder
and RET 54_ transformer terminals.
Supporting a wide range of communication protocols, including SPA, LON,
IEC 60870-5-103, DNP 3.0 and Modbus RTU/ASCII, commonly used by utilities
and industries, the terminals are flexibly integrated into different control systems.
Connection to Profibus DP or IEC 61850 based systems is possible via the interface
adapters SPA-ZC 302 or SPA-ZC 400.
