چکیده

In this paper, a calculation method of the sheath circulating current is introduced, taking the different grounding types, laying environment, structural parameters of cables into account. Due to the parameters in practice, the circulating currents in sheath are calculated and measured under the conditions of singlepoint grounding and both-end crossbonded grounding. The possible causes, which lead to high circulating current, are discussed based on the calculation method.

Adaptive soil model for real-time thermal rating of underground power cables

This study presents a validated adaptive method intended for real-time thermal rating (RTTR) of underground power cables. The accuracy of the RTTR algorithm, when producing emergency ratings or predictive calculations, strongly depends on the following parameters (which have large uncertainties): correct soil modelling, the proper determination of the soil properties and the accurate estimation...

Underground contour (UGC) mapping using potential field, well log and comparing with seismic interpretation in Lavarestan area

Coastal Fars gravimetry project in Fars province was carried out to find the buried salt domes and to determine characteristics of faults in this area. The Lavarestan structure was covered by 4203 gravimetry stations in a regular grid of 1000*250 m. Depth structural model of this anticline made in previous studies was based on geological evidences and structural geology measurements. In order t...

Characterization of 3-strap antennas in ASDEX Upgrade

The response of the local RF current measured at limiters of 3-strap ICRF antenna to variations of power balance and phasing at fICRF=30MHz agrees qualitatively well with EM calculations by TOPICA and RAPLICASOL codes. Measurements of tungsten sputtering yield and DC current at the limiters correlate strongly with the local RF current. In contrast to findings for the 2-strap antennas, values of...
