The acceptability and also the acceleration ofrenewable energy technologies is tightly linked with a betterunderstanding of dynamic behavior of drive train componentsand their interactions. This ultimate understanding of systemcharacteristics can only be achieved with comprehensiveexperimental investigations on different phenomena of largeelectrical generators. This leads consequently to a betterverification of numerical and analytical models of largegenerators. The large generator-converter lab which is discussedin this paper is a unique opportunity for deep experimentalinvestigations on large hydro and wind generators. It is designedto deal with the current as well as future research topics in thefield of wind and hydro generators and their interactions withpower electronic devices and electrical grid.

“…Rogowski coil has many advantages such as simplicity of construction, use, and modeling as well as the capability for measuring currents in a very wide range of amplitudes and bandwidths. Therefore, the Rogowski coil is widely used in many applications such as monitoring partial discharges [12][13][14], transient currents [7,[15][16][17][18] as well as power frequency currents [19]. For modeling Rogowski coil, there are two main models, lumped and distributed, which are suitable for high frequency measurements [20].…”

Rogowski coils (RCs) are widely used to measure power or high frequency currents based on their design. In this paper, two types of RCs that are circular (traditional) and cylindrical shapes wound using wire covered by varnish are constructed. This construction is carried out to be suitable for monitoring the discharge current of the surge arrester installed in the distribution system. Concerning high frequency RC modeling for both types considering transfer function is introduced. Self-integrating for both types is attained. Therefore, the experimental tests using function generator for both coils are carried out to identify the parameters of the transfer function representing the introduced model. The measured signals for current and induced voltages are denoised for the parameter identification process. The denoised process is achieved using the MATLAB code 'wdenoise' while the parameters are estimated using the system identification toolbox. Verification of the proposed model is achieved using experimental results for the two coils. The sensitivity of the two coils is investigated based on the induced output voltage. The application concerning the two coils for monitoring the discharge current of the surge arrester is done. The results confirm the accuracy of the introduced RC model, as well as the performance of the cylindrical shape, is better than the traditional one. The simulation is carried out using MATLAB and ATPDraw programs.
