APPLICATION OF ISOLATION AMPLIFIER IN MEASUREMENT OF FLOATING AC SIGNAL

Luka Ferković

Abstract

Measuring procedures in some cases require connection of two measuring objects or parts of equipment which terminals should not have common potential. Achievement of these requirements is inappropriate by using the transformer coupling because of its non-linear transfer function. Optical transfer of digital signals by using optocoupler provides the precision and stability needed to accurately signal monitoring.
