A semiconductor directional resistance relay is described which uses a device based on the principle of phase transformation during frequency multiplication and division for the elimination of a ″dead zone″ . The main element of the device is an electromagnetic parametric frequency divider. The voltage at the output of the parametric frequency divider, supplied to the relay for the elimination of the ″dead zone″ , depends, as regards its value and phase, both on the value of the short-circuiting current and on the value of the final voltage.
