Design of Rogowski Coil with external integrator for measurement of lightning current up to 400kA
Lightning is one of the most serious disasters in the electrical power grid, especially in the ultra-high and extra-high voltage power systems. The measurement of the lightning current parameters is of great importance for the investigation of lightning protection. The literature shows given its significant advantages over equivalent current transducers, the Rogowski coil is an increasingly pop...
متن کاملDesign Modification of Rogowski Coil for Current Measurement in Low Frequency
The principle object of this paper is to offer a modified design of Rogowski coil based on its frequency response. The improvement of the integrator circuit for nullifying the phase difference between the waveforms of the measured-current and the corresponding terminal voltage is a further object of this investigation. This paper addresses an accurate, yet more efficient measuring and protect...
متن کاملHigh Frequency Characteristic of Rogowski Coil
According to the transfer impedance getting from distributed parameter model,we analyse the influences of magnetic conductivity , the number of turns ,capacitance to the shield and interturn capacitance on the high frequency characteristic of Rogowski coil through theories and simulations. Simulation shows that there are a series of zeros in high frequency band, but on the whole, the high frequ...

متن کاملAnalysis of Rogowski Coil Behavior under Non Ideal Measurement Conditions
− This work illustrates an analysis of Rogowski coils for power applications, when operating under non ideal measurement conditions. The developed numerical model, validated by comparison with other methods and experiments, enables to investigate the effects of the geometrical and constructive parameters on the measurement behavior of the coil.
