METHOD FOR OBTAINING 50 HZ ALTERNATIVE ELECTRIC SIGNALS, DEPHASED AT 88 DEGREES IN COMPARISON TO THE NETWORK

摘要

the invention refers to a method for obtaining electrical signals anda machine alternative 50 hz supply network phasing from an angle of 88 degree + - 3 degree and amplitude devine from zero to a maximum of 50 mv with special protection of the environment and electrical for parasites with a linear transfer characteristic in a wide frequency band as.the method according to the invention uses a galvanically isolated from the electronic entry and exit, the phase shift which is a passive network of impedanta constant.eliminating parasitic signals is accomplished by simetrizarea signal out front of earth mass.the apparatus according to the invention, realizes a magnetic face protection network: for example in the lem 2 (loch electromagnetic).
