Remote Wireless Calibration of Equipment in the Distributed Measurement Systems

This paper presents possibilities of the GSM/GPRS communication network for remote wireless calibration of the measurement equipment used for metrological assurance of the distributed measurement systems. An automated calibration procedure is performed by the measurement data transmitting between calibrator unit in the control center and fixed or mobile remote measurement stations, using synchro timing distribution system. Such calibration procedure is implemented in distributed system for metrological support of power quality monitoring and analyzing, aimed to increase an efficiency of energy delivery and consumption. By means of the Lab VIEW application software, a virtual instrument for the measurement, recording and statistical processing of the measured power quality parameters, defined according to the relevant European quality standard EN 50160, is developed and implemented in this system.
