Method of breaking electric networks for measurement of parameters of network components

摘要

A method for creating "virtual" open circuitry in electric networks for the purpose of measuring the parameters of individual network components with either D.C. or A.C. methods of measurement. The method provides the possibility of a full or partial isolation of an element from a network, thus eliminating the shunting effect of the network. The method may be used for the automatic checking of parameters of passive and active components of electronic systems and installations. The circuit consists of a voltage follower whose amplification factor is close to a unity, said follower having a very high input impedance. The cathode follower is appropriately connected to adjacent network vertices which are connected with a junction of the components to be measured through a branch to be broken in order to provide isolation.
