To ensure a trouble-free and reliable operation, any power system requires a telecommunication system of its own, enabling the transmission of various kinds of information, speech, data and teleprotection. In addition to standard telecommunication technologies, the power industry also uses HV Power Line Carrier Communication, utilizing high-voltage power lines as the transmission medium. Iskra has been developing, marketing and manufacturing such equipment for more than half a century. Today, we can offer our customers and users on every continent contemporary PLC equipment, meeting the standardized IEC recommendations as well as specific requirements of individual users, particularly in the territory of the former Soviet Union.

Teleprotection is a special function used for communication between protection relays. Protection commands are transmitted via analog channels (PLC, MUX) or digital channels (SDH/PDH, radio, optical fibers). Iskra Sistemi is manufacturing teleprotection equipment according to IEC standards as well according to standards used in special protection schemes for radial networks.
