Contribution deals with automated measurements of mechanical parameters and current carrying capacity of selected Aluminum-conductor Steel-reinforced (ACSR) cables and a combined optical ground cable. After a detail description of realized tests indication of future use of obtained results follow.
Increase of mechanical immunity of LV cables wrapped around the steel tape and with the final plastic coating can achieve a significant reduction in the likelihood of failure caused by improper / negligent installation and the occurrence of unforeseen mechanical factors. For cables with internal sealed a three-phase system, it may be a good choice. Substantial problems may arise when single-core cable...
The paper presents a finite element method for numerical calculation of magnetic flux density around a high voltage power transmission line. The need of such calculation is based on growing safety demands of people exposed to the action of external magnetic field as well as reduce the cost of people protection. Method extends the calculation of magnetic flux density around the straight infinite conductor...
Contribution deals with the problem of insulating system's condition diagnosing with aim to upgrade the level of its real state ranking. After the description of diagnosing methodology used real on-site acquired data are presented. Main accent is at monitoring of discharge activities. This method is perhaps the only, which enables to detect smaller anomalies in high-voltage insulation systems as well...
This paper presents different computation techniques of electrical parameters of an untransposed multiconductor overhead transmission lines. The advances of those methods are that they can be used on any tower structure operated on any voltage level with great precision. Using matrix calculus, no such serious approximations as in common transposed line parameters are used. There is shown how to progress...
Contribution deals with comparison of mechanical parameters and current carrying capacity of a new Aluminum-conductor Steel-reinforced cable, an operated one and a combined optical ground cable. After a detail description of realized tests indication of future use of obtained results follow.
