Feeder Protection Relay – S24 Series

  • :Protecta/EU
  • :18 months from date of shipment or on request

The IED EP+ S24 Series is member of the EuroProt+ numerical protection relay, made by Protecta Co. Ltd. The EuroProt+ type complex protection in respect of hardware and software is modular device. The modules are assembled and configured according to the requirements, and then the software determines the functions. The IED EP+ S24 Series is  contained a special selection of the EuroProt+ modules, bearing in mind the cost effective realization. The IED EP+ S24 Series is divided into several different variants corresponding to the scope of application.

Depending on the standard configuration chosen (Variant 1, Variant2,…), the IED is adapted to the protection of medium-voltage feeders in isolated neutral, resistance earthed, compensated and solidly earthed networks. Once the application-specific settings have been defined for the standard configuration IED, it can be put into service directly. Areas of application include protection functions for a large variety of applications, e.g. transformer differential and restricted earth fault protection, frequency and voltage based protection, motor protection, thermal overload protection.

SCOPE OF APPLICATION

The IED-EP+ S24 Series is available in four predefined standard configurations to suit the most common feeder management application.

  • Variant 0 serves as a simple bay control unit.
  • Variant 1 is configed for non-directional overcurrent protection relay.
  • Variant 2 is configed for directional overcurrent protection relay.
  • Variant 6 is dedicated for those application where is only voltage and frequency based protection functions are required.
