The Possibilities of Data Communication for Telemetry Systems in Energetics

The paper describes the possibilities of communication lines for automated data collection from any energy meter installed on the client's side. There are compared some types of communicatin lines, classical modem communication over PSTN, TCP/IP communication over Internet and PLC (Power Line Communication) - communication over power electrical distribution chain. The main focus is presented to PLC system. The remote data acquisition is modern trend for metering of energy, gas, water, heating steam etc.
