Tele – protection equipment transmits the Trip Command from the Protection Relaying Schemes in Power Station and Sub – stations. Tele – protection links using power line carrier channels are the most economical way of performing all the tasks associated with transmitting Trip Commands. Security, dependability and transmission time are the important characteristics of any Tele – protection equipment. Interference in the communication channels should neither be interpreted as a Trip Command (Security) nor in admissibly delay the transmission of Genuine Trip Commands (Dependability and Txn time).
