Teleprotection

A secure and uninterrupted supply of electricity is only possible with the help of comprehensive protection and control functions, which ensure the reliable operation of the power system.

As the complexity and ratings of electrical power systems increase, so do also the demands on the protective devices and systems which have to protect them from damage and preserve power system stability.

Protection relays in conjunction with communication links provide the best possible means of selectively isolating faults on HV lines, transformers, reactors, and other important items of electrical plants.

To prevent the system from failure and damage, the teleprotection system has to selectively disconnect the faulty part by transferring command signals within the shortest possible time.
