Special Power Supply for Measuring Systems

Vaclav Papez, Stanislava Papezova

Abstract

The functions of measuring instruments and measured equipments are always affected by technical parameters of the electrical energy, which supplies apparatus and arrangements. Disturbing signals, which are spread by power line along the supply system or by the form of radiated electromagnetic waves, get through measuring circuits. The relevance of all effects grows up with the increasing of the accuracy and sensitivity of taken measurements. In this paper there are analysed parameters of typical sources that are used for power supply of measuring instruments in laboratory. There is described the construction of a special source with minimal distortion too.
