The Remote Control of Power Supplies – Experience of Exploitation

Abstract

The remote control of power supplies has been developed according to Telecom Serbia’s technical requirements. It has been exploited for five years. From this system specially developed for the needs of a telecom company, it has evolved into a universal system. After five years of usage of SDNU, analysis and systematization of the detected problems were carried out. The data were collected from about 200 external devices. The analysed objects were of the first priority, located in larger cities, but also objects in inaccessible locations far from the city. The identified problems were grouped into four categories. According to classification of the problem, recommendations about SDNU users’ work organisation were made in order to exploit the results effectively. This paper presents the characteristic forms of signals for every category of the detected problems.
