چکیده
The paper presents a method for digital compensation of the ratio and phase angle errors resistive voltage divider. system consists separate electrical circuit divider, based on National Instruments (NI) PCI eXtension Instrumentation (PXI) PXI-5922 acquisition cards (DAQ). A novel approach to real-time is presented, using signal processing. algorithm Wiener filtering finite-impulse-response (FIR) filters. proposed compensation, FIR filtration NI PXI DAQs, gives maximum magnitude error below 400 ppm 4500 μrad, in frequency band 50 Hz–100 kHz. allows fine-tuning adjust possible change original transfer function due aging components.

Resistive power divider for magneto-inductive waveguides
Addressing the need for passive magneto-inductive components, a lumped-element symmetric power divider has been designed and realised for a magneto-inductive cable with the resonant frequency of 95 MHz and the passband between 73 and 174 MHz. In agreement with the theory, the measured coupling loss is 6 dB for most of the passband independent of the input port. Having proved useful for magneto-...
متن کاملA model-based PDPC method for control of BDFRG under unbalanced grid voltage condition using power compensation strategy
Brushless doubly fed reluctance generator (BDFRG) has been recently suggested as a wind generator. Different control methods are presented in literature for the BDFRG, but there is a gap on control under unbalanced grid voltage condition (UGVC). This paper presents a predictive direct power control (PDPC) method for the BDFRG under UGVC. The proposed PDPC method is based on power compensation s...
متن کاملThe Design and Characterization of a Prototype Wideband Voltage Sensor Based on a Resistive Divider
The most important advantage of voltage dividers over traditional voltage transformers is that voltage dividers do not have an iron core with non-linear hysteresis characteristics. The voltage dividers have a linear behavior with respect to over-voltages and a flat frequency response larger frequency range. The weak point of a voltage divider is the influence of external high-voltage (HV) and e...
متن کاملA Novel Voltage Divider Circuit
A novel analog divider is described in this paper. The circuit enables the division of a dc voltage with another dc voltage. The constant of the division is dependent upon a third dc voltage and a pair of resistors. Employing a precision source for the third dc voltage and matched resistors, an acceptable level of accuracy can be obtained. Keywords-sawtooth wave; integrator; comparator; analo...
متن کاملNonlinear voltage divider
This paper is focused on how to implement a nonlinear voltage divider used in the electrical power network disturbances measurement system preconditioning circuit. The voltages acquired from the electrical power network have amplitudes between 0.2 kV and 10 kV, values which are very high for an acquisition board. These amplitudes must be reduced to the values accepted by the acquisition boards:...
