Method of transmission signals for controlling electric consumers in networks 0,38 kv

Dispersed agricultural electroconsumers and their location in areas with poor communications network often complicates the application of known methods of transmitting control signals based on radio communications and high-frequency power transmission lines (PTL). But beyond that, you can transmit signals on the transmission line at the power frequency. It was developed a method for transmitting control signals over the power lines to the power frequency. This article describes the principle of signal transmission as an example to control two electric consumers. Changing the network mode, using the parameters described in the theory of symmetrical components.
