Protection of Telecommunication Systems in Electric Power Facilities from Electromagnetic Pulse (EMP)

Telecommunication systems of electric power facilities play an important role in data transceiving, telemetry, remote control and communication. At the same time, these systems are the most sensitive to, and the least protected from, High Altitude Electromagnetic Pulse (HEMP), compared to other important electric and electronic systems used in the electric power industry. This situation cannot be perceived as normal and thus calls for corresponding actions. Unfortunately, renowned technical means are often very expensive, and regardless of advertisement, claims they do not always ensure reliable HEMP-protection of telecommunication systems. An analysis of the situation and a new solution for the problem is presented in this article.
