Abstract
Method for determination of angle of phase shift between voltages in two node points of electric network is based on formation of primary (support) signal of voltage in network in nearest node point, with telemetric transfer of angle of phase shift of secondary signal to that point, this is formed in remote node point of electric network, with measurement of phase shift that is being looked for in nearest node point, between primary and secondary signals. Secondary signal is formed through short-time “dips” of voltage in network in remote node point twice by period for voltage in network at instants when angle of phase shift with respect to transfer of secondary voltage through zero takes given values α and π + α. One points out in electric signal propagating by the electric network voltage “dips” in nearest node point as secondary pulse signals. Primary pulse signals are formed with phase shift with respect to transition of voltage in network through zero as equal to values α and π + α pointed out above.
