E1-Line is a dedicated transmission overhead line and cable protection, control and automation IED. The relay provides complex protection, control and monitoring functions. It is member of the DTVA product type in the EuroProt+ product family. The EuroProt+ family complex protection – in respect of hardware and software – is a modular device. Because of the modular architecture, the modules are assembled and configured according to the user’s requirements; from that point on, the software determines the functions.
The protection relays provide a variety of versatile protection functions along with the main line distance protection (21) such as teleprotection schemes (POTT, PUTT etc.), current protection (50/51, 50/51N, 67/67N, 46/46BC), voltage protection (27, 59, 47), frequency protection (81U/81O/81R), power protection (32/37), power swing/out of step detection (68/78), switch on to fault protection (SOTF), breaker failure protection (50BF). The scope of functions is supplemented with the automatic reclosing function (79) with synchro-check/synchro-switch feature (25). Voltage transformer supervision and dead line detection function are implemented in the configuration. Because of the implemented control, measuring and monitoring function, the IED can also be used as a bay control unit.
