E2-LINE DISTANCE PROTECTION

E2-LINE DISTANCE PROTECTION

E2-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 a 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 DTVA product type is configured to protect, control and supervise the elements of the transmission network, where systems are typicallysolidly grounded worldwide. In these  networks single phase-to-ground faults result in high currents comparable to line-to-line faults; therefore, both types of faults need fast protection functions.

The relay can be used for single- or three-phase tripping and it supports double breaker terminals such as breaker and a half or ring bus topology.

The main protection functions of the DTVA type  include high-speed distance protection with five independent protection zones and line differential protection. The relays support the general teleprotection schemes (POTT, PUTT etc.).

Additionally the DTVA product type includes a variety of versatile protection functions: directional and nondirectional overcurrent protection, voltage-based protection and frequency-based protection.

The HV automatic reclosing function provides multishot autoreclosing with a synchro-check feature. The dead times can be set individually for each cycle and separately for single-phase faults and multi-phase faults.

Because of the implemented control, measuring and monitoring function, the IED can also be used as a bay control unit.

The EuroCAP configuration tool, which is available free of charge, offers a user-friendly and flexible application for protection, control and measurement
functions to ensure that the IED-EP+ devices are fully customisable.
