Circuit to inhibit voltage and current returns to the electric power distribution line in an inverter-type power plant

摘要

The present invention is applicable for inverter-type power plants where the electric distribution line is used as stand-by unit. The present invention is composed of a ballast impedance and an electric mesh including an energizing circuit of a first section suitable for insulating a power plant from the distribution line; contacts of a second section which are monitored by a supervisory control circuit of the power plant; and an electric probe for making available a voltage or a current measurement when current flows through the distribution line.
