“…In this section, the proposed Rogowski coil modeling is evaluated for monitoring surge arrester discharge currents for the electric power distribution networks. One of the motivations behind this application is that the Rogowski coil can be easily and cheaply installed with a surge arrester in the distribution system [7]. However, the Rogowski coil utilized in [7] was differentiating type, and an additional digital integrating process was implemented to monitor the arrester discharge current that was utilized to calculate the dissipating energy for controlling the triacs triggering.…”

“…Surge arresters are commonly used to protect the distribution systems from lightning overvoltages by discharging lightning strokes. However, they can be burned out due to excess discharge energy behind their capabilities, especially under direct lightning strokes [7,8]. Therefore, monitoring the surge arrester discharge current is essential for estimating the discharge energy and protecting it from burning out.…”

“…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.

The present article highlights the atypical power grid resilience of the northernmost point of the African countries against repeated acts of vandalism on its MV distribution lines. To counter this threat, the present article reports a comparison between a 3-wire and 4-wire MV power grid in the event of a single-phase or three-phase short-circuits. The evolution of the voltage of the healthy phases during a single-phase fault and the impact on the power supply signal are mathematically studied. The study shows that an adequate resizing of the protection devices is sufficient to operate the MALT system in complete safety without its neutral wire. Thus, by allowing saving copper wire, this finding is actually a turning point in the implementation of the malt system. To better contextualize this result, which was actually initicated by an unpleasant experience, the article begins with a historical assessment of the 30 kV 4-wire MALT electrical distribution systems and a technical calibration of its specificities in relation to the two conventional practices of standard IEC 60038.
