Overview
42HP wide42HP wide back84HP

The E5-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.

Application
42HP wide42HP wide back84HP

The E5-Feeder relay is the functional extension of the E3-Feeder IED. The range of functions includes all current- and voltage-based applications (directional overcurrent and directional earth-fault protection, power calculation and over- and undervoltage, frequency protection), including the line differential protection function.
 
All the control and monitoring functions necessary for switchgear control and monitoring are included in the E5-Feeder relay. The automatic reclosing function 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)
  • Line differential protection with CT saturation detection
  • Transformers and compensating coils with capability to handle the protection zone
  • Optional restricted earth-fault protection
  • Switchgear automation and control
  • Interlocking schemes can be defined by the user
  • Current transformer supervision through unbalance protection
  • Voltage transformer supervision and dead line detection
  • 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 against island operation for wind farm and photovoltaic energy applications

 

Protection & Control functions

The E5-Feeder configuration measures three phase currents, the residual current and, additionally, three phase voltages and the residual voltage. The main protection function in this application is the line differential protection function. It can also be used if there is transformer in the protection zone (optional feature) . The communication hardware module sends and receives phase current vectors to realize this function. The range of functions is supplemented with the automatic reclosing function.
