FOUR-PARAMETER SINE-FITTING ALGORITHM FOR DETECTION AND CLASSIFICATION OF TRANSIENTS AND WAVEFORM DISTORTIONS
This paper describes a new method for detection of some power quality (PQ) disturbances, namely transients and waveform distortions. The proposed algorithm is based on a modified version of the four-parameter sine-fitti...
ANALYSIS OF A THREE-VOLTMETER MEASUREMENT METHOD DESIGNED FOR LOW-FREQUENCY IMPEDANCE COMPARISONS
The principle of the three voltmeter method designed for precise impedance comparison is presented. Generalization of the classical approach is proposed and analysed. Formulas for impedance parameters determination are d...
THE IMPACT OF THE RANDOMIZATION OF THE QUANTIZATION ERROR ON THE ACCURACY OF MEASURING SYSTEMS APPLYING A DIGITAL MEASURING ALGORITHM
In measuring systems applying a digital measuring algorithm, the measurement process is divided into two stages: Stage 1 consists in the acquisition and storage of the system's input data, based on which the value of the...
TWO-PARAMETER MEASUREMENTS AND SIGNAL CONDITIONING IN DOUBLE-CURRENT SUPPLY FOUR-TERMINAL RESISTANCE CIRCUITS
A new type of the four-terminal (4T) bridge circuit unconventionally supplied by current sources connected in parallel to opposite arms, named double current bridge (2J) is presented. It has two different outputs from bo...
CALIBRATION OF EXTREMELY SENSITIVE RANGES OF DC PICOAMMETERS WITH ANALOG ACTIVE I/U CONVERSION
The paper deals with the problem of calibration of extremely sensitive picoammeters with measuring ranges close to limits of the measuring possibilities. The presented method of calibration bases on a resistive source of...
