DIGITAL MEASUREMENT OF TRANSIENT DISTURBANCES IN ELECTRIC POWER NETWORK WITH ADDITIONAL LOWPASS ANALOG CIRCUIT<br />
The paper presents a DSP-based system for measurement of the short-term transient distortions in electric power networks. These distortions typically possess short duration times and high amplitude values and thus they a...
A TRANSDUCER INTERFACE FOR RESISTIVE SENSOR ELEMENTS BASED ON THE USE OF A FLIP-FLOP<br />
This paper presents a new transducer interface. This interface serves the resistive bridges. The A/D conversion is based on the use of an auto-compensatory system with two digital-to-analog converters (DACs). A new measu...
THE EFFECT OF DOUBLE VENTURI'S STRUCTURAL PARAMETERS ON THE REINFORCEMENT VALUE AND FLOW COEFFICIENT
Reinforcement factor of a double Venturi is one of the more important parameters related to sensor shape and structure. The evaluation and the effect of the double Venturi's structural parameters on its value were carrie...
QUALITY ASSESSMENT OF HIGH VOLTAGE VARISTORS BY THIRD HARMONIC INDEX
High voltage varistors that consist mainly of grained ZnO have to be tested before assembling into a surge arrester. The existing methods demand a usage of high voltages and intensive currents that is inconvenient, destr...
MEASUREMENT UNCERTAINTY CONTRIBUTION TO THE MLP NEURAL NETWORK LEARNING ALGORITHM APPLIED TO AERODYNAMIC EXTERNAL BALANCE CALIBRATION CURVE FITTING
The aim of this study is to fit a calibration curve to a multivariate measurement system considering uncertainty in load measurements. The experimental data are generated from the calibration of the aerodynamic external...
