Overview
42HP wide84HP wide84HP backplane

The E4-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.

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 the line differential protections are also capable of protecting 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.

Application
42HP wide84HP wide84HP backplane

The E4-Feeder relay is designed to provide protection for a complex field unit of overhead lines and cables on compensated or impedance grounded networks.  The main protection function of the IED is distance protection, which can also handle so-called cross-country-faults.

The impletented functions cover a wide range of current- and voltage-based applications: directional overcurrent and directional earth-fault protection, power calculation and over- and undervoltage. Frequency protection functions are also included.

All the functions necessary for switchgear control and monitoring are included in the E4-Feeder relay. Automatic reclosing function with synchro-check capability is also included.

Scope of application

  • Overhead lines and underground cables (back-up protection on HV systems) overcurrent protection
  • Directional ground fault detection in systems with isolated, resistance earthed and Petersen coil earthed neutral, based on residual directional overcurrent protection
  • Directional over-/underpower protection with user-defined power setting values and operation angles (combined solution for active or reactive power)
  • Five independent distance protection zones with polygon-shaped characteristics.
    • Handling of cross-country faults (the phase preference can be defined by parameter)
  • Built-in fault locator
  • Switchgear automation and control with synchro-check option
  • User-defined interlocking schemes
  • Current transformer supervision through unbalance protection
  • Voltage transformer supervision and dead line detection
  • Back-up protection unit for transformers, lines, generators, motors, busbars of all voltage levels
  • Sensitive directional ground-fault detection for static ground faults
  • Sensitive directional ground-fault detection for transient and static ground faults (transient function)
  • Inrush detection and blocking
  • Reverse power protection
  • Distribution load shedding schemes

 

Protection & Control functions

The E4-Feeder IED measures three phase currents, the residual current and, additionally, three phase voltages and the busbar voltage. These measurements allow, in addition to the current- and voltage-based functions, directionality extension of the configured phase and residual overcurrent functions, directional over- or underpower functions as well as frequency-based protection functions.

The main protection function in this application is the distance protection function. Basically, this function generates three-phase trip commands, but in the event of cross-country faults it also makes use of the phase preference logic. The range of functions is supplemented with the automatic reclosing function and synchro-check.
