<p>The circuit is suitable for application to inverter-type power plants where the electric distribution line (RD) is used as stand-by unit. The circuit is composed by a ballast impedance (I) and by an electric mesh comprising: the energizing circuit of first sectioning means (S1) suitable to insulate power plant from the distribution line (RD); the contacts of second sectioning means (S2) which are monitored by the supervisory means (SM) of the power plant; an electric probe (SE) suitable to make available a voltage or a current when current flows through said distribution line (RD).</p> |
