Importance of Supply’s Quality in Calibration Laboratory.

Abstract

In a calibration laboratory at the time of carrying out electrical measures of physics magnitudes, and upper reliability is required in order to get results of high precision. Within protections and security measures, some aspects must be considered as electrical, while another, as temperature and ambiental conditions, must not.

Focusing on electrical aspects we must have into consideration that the quality of the measure rested on a reliable power source.

An sabilized feed voltage ia a sign of quality and it can be obtained by two different ways. One of them is to get it from combined cycles, the other is to use an Uninterrupted Power Supply (UPS), since an UPS removes disturbances of the net, which could impede the correct measure and calibration of instruments.

In order to have a supply with requared quality, which means to have an stable voltage, both in permanent regime and in transitory regime, the use of UPS's becomes necessary and recomendable.

An special care must be have with micocuts, because these connections and disconnections cause anomalities in the sistem's operation, and the apearance of possible tips of voltage, which is not less important, UPS equipement are the ones that better conterac disturbances of the wave.
