42HP wide42HP wide back84HP

The E2-Feeder is a dedicated feeder protection and control IED; it is member of the DTIVA product type in the EuroProt+ product family.
The DTIVA products are configured to protect, control and supervise elements of the utility and industrial distribution systems, including radial, looped and meshed distribution networks. 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 main areas of application are the not solidly grounded radial networks. Here the application of Petersen coils or grounding resistances results relatively low currents in case of single phase-to-ground faults. The majority of the protections are based on current measurements only, but the application of distributed generation or loops in the network topology require additional voltage measurement and directional protection functions. The distance and line differential protections are also available to protect compensated or isolated networks.

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.

The E2-Feeder provides all the protection and control functions offered by the E1-Feeder relay: 3Ph+Io overcurrent protection, switchgears control (and CB monitoring).
The E2-Feeder IED has voltage measurement input; this additional voltage measurement is the basis of the directional decision for earth-fault protection, power calculation and over- and undervoltage functions.
It is designed to be the main or back-up protection of overhead lines and cables on distribution networks (or HV systems) where the directional decision is essential for proper functioning.
The configured functions are based on current and voltage measurements and they are supplemented with an automatic reclosing function.

scope of application:

  • Overhead lines and underground cables (back-up protection on HV systems) overcurrent protection
  • Directional phase and ground fault detection in systems with isolated, resistance earthed and Petersen coil earthed neutral
  • Directional over-/underpower protection with user-defined power setting values and operation angles (combined solution for active or reactive power)
  • Switchgear automation and control
  • User-defined interlocking schemes
  • Current transformer supervision through unbalance protection
  • Inrush detection and blocking
  • Back-up protection unit for transformers, lines, generators, motors, busbars of all voltage levels
  • Optional decentralized busbar protection sub-unit application
  • Sensitive directional ground-fault detection for static ground faults
  • Available sensitive directional ground-fault detection for transient earth faults
  • Inrush detection and blocking
  • Reverse power protection
  • Protection against islanding operation for wind farm and photovoltaic energy applications
  • Bay control unit application capability


Protection & Control functions

The E2-Feeder configuration measures three phase currents, the zero sequence current component and, additionally, three phase voltages and the residual voltage. These measurements allow, in addition to the current- and voltage-based functions, directionality extension of the residual overcurrent function and also directional over- or underpower functions. The range of functions is supplemented with the automatic reclosing function.
