Calibration of Instrument Current Transformers with Atypical Secondary Current
نویسندگان
چکیده
− Methods enabling a determination of errors εI and δI for a high transformation ratio difference between a standard and tested instrument current transformers (ICT) are described in this article. A widespread method uses an automatic transformer test set for the measurement of a difference between a standard and tested ICT. A method transforming secondary currents to voltages and an indirect method using error measurement from magnetizing current are also described.

Uncertainty in measurements of power and energy on power networks
The problem on measurement of power and energy in single-phase and three-phase networks is always very important. The accuracy and precision of measurement is of equal importance for both manufacturers and consumers. The general problem is to determine the uncertainty of the energy produced in a specified power station and delivered to different consumers. Measuring instruments used for energy ...
متن کاملCalibration of High Accuracy Class Standard Current Transformers
Main characteristic of high accuracy class current transformers is very small amplitude and phase errors (approximately 10 ppm). Such an error is a reason of complexity and sensitiveness of that metrological task. This paper presents a new method for high accuracy class current transformers calibration simultaneously with two different measuring apparatus. The method is presented as well as mea...

The current study shows a calibration method in gas chromatography (GC) with detection by mass spectrometry (MS) to quantify polychlorinated biphenyls (PCBs) present in transformer oils. The calibration was carried out with a secondary standard composed of a mixture of Aroclors (A1254:A1260), in one to one proportion and a reference standard (1,3,5-trichlorobenzene). This last one was used to e...

This paper presents a new method for evaluation and simulation of inrush current in various transformers using operational matrices and Hartley transform. Unlike most of the previous works, time and frequency domain calculations are conducted simultaneously. Mathematical equations are first represented to compute the inrush current based on reiteration and then Hartley transform is used to stud...
متن کاملElectronic Voltage and Current Transformers Testing Device
A method for testing electronic instrument transformers is described, including electronic voltage and current transformers (EVTs, ECTs) with both analog and digital outputs. A testing device prototype is developed. It is based on digital signal processing of the signals that are measured at the secondary outputs of the tested transformer and the reference transformer when the same excitation s...
