The E7-Feeder is a dedicated motor 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. 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 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 E7-Feeder configuration is designed to protect, control and supervise medium- to large-sized three-phase motors in the manufacturing and processing industries. The IED provides a wide range of protection functions, which are based on current, voltage and temperature measurements: non-directional overcurrent, directional earth fault protection, various voltage protection functions (over-/undervoltage, negative, positive sequence, residual voltage protection),
In addition to these basic functions, the relay provides a number of other special motor protection and supervision functions that enable it to protect and run the motor more effectively and safely: motor thermal protection, motor startup supervision, asymmetry protection, loss of load protection, prolonged start locked rotor protection.
The motor differential protection function is available as an option in the E7-Feeder relay.
The relay can record the starting current, which is most helpful in analysing motor performance during the critical start-up period.
Furthermore, the relay offers control, measuring and monitoring functions; consequently, the IED can be used as a bay control device.
Scope of application
- Protect motors in industrial networks and power plants
- Protection against thermal overload of the stator and rotor
- Monitoring the thermal state of the motor by motor thermal replica function
- Voltage transformer supervision
- Phase reversal protection with negative sequence overvoltage protection
- Motor start-up supervision
- Overload detection while in use
- Temperature monitoring via temperature sensors with RTD module
- Loss-of-load (undercurrent) protection
- Protection against instability due to undervoltage
- Differential protection for internal phase-to-phase or phase-to-ground faults
- Back-up protection unit application
The E7-Feeder configuration is designed to protect large motors on the medium-voltage network. It measures three phase currents, the residual current and, additionally, three phase voltages and the residual voltage. These measurements facilitate the operation of current- and voltage-based functions.
In addition to the usual overcurrent and overvoltage functions, this configuration includes special motor protection functions such as a dedicated thermal replica function for motors, negative sequence overcurrent protection function, asymmetry protection, loss of load protection, motor startup supervision. Alternatively, the E7-Feeder unit may be applied as a differential protection together with the optional motor differential protection.
