General Description

Electrical protection systems play an important role within power systems. Nowadays it is unthinkable a national grid without advanced and coordinated protection relays. Protection relays are essential to protect electrical and electronic devices, transmission lines, power stations, etc. which form the whole electrical system.

There are a great variety of protection relays in the industry: overcurrent protection relays, over/under frequency protection relays, over/ under voltage protection relay, distance protection relay, directional/non-directional protection relay, feeder management protection relay, etc. However it is necessary a great amount of knowledge to understand how configure and manage these types of protection relays.

The Protection Relays Test Aplication, "ERP", is one of the most advanced and safe equipment in the market for studying the operation of protection relays used in real electrical substations. This equipment provides students, professors and researchers with the necessary knowledge and experience in the field of high voltage protection and cyber security relays.

This application can be acquired in two ways:

  • As a complete application, under the reference "ERP", which includes all the protection relays and accessories mentioned in this catalog.
  • As a modular equipment, under the reference "ERP-UB", which includes exclusively the references "AE1" and "ERP-MF", being required, at least one, the protection relays exposed in this catalog for the realization of the practical exercises.

The Protection Relays Base Unit, "ERP-UB", is the main element where electrical tests and interconnections are carried out.
