Electric power utilities are probably the largest users of real-time data in World. The minute by minute operation of the power network involves communication systems for system supervision SCADA, tele-control and tele-protection, With the introduction of microprocessor technology and the need to manage the asset more effectively, the growth in communications has been explosive. This paper discusses the communication systems and signaling methods with particular interest in the operation of the relaying function and in their interaction with the other power network protection and control systems. Also the availability of a common communications standard, which is particular important for transfer tripping and trip acceleration application, and for status and alarm data transfer within the network's supervisory and control systems will also be discussed.
