Virtual instrumentation system for training in the field of the influence of Power Equipment on Telecommunication Lines

The main topic of this article is related to a didactic methodology used for the IT based assessment of the influence of Power Lines and Equipment on Telecommunication Lines. Power is needed as well as telecommunications are in our society today. Power head lines are parallel or crossed with telecommunication ones, so influences could be electric, magnetic or even resistive ones. All these interferences, individual and together, could cause injuries to telecommunication human operators or great damages on the IT equipment. This paper presents first a computational method used for a better overview on this subject, by assessing the values of the capacitive current, capacitive voltage, longitudinal induced voltage, resistive voltage, psofometric voltage. The architecture of the proposed system, both hardware and software, is briefly described after, as well as a teaching methodology proposed in order to present all these aspects to students or interested personnel. Some teaching examples are shown at the end of the paper.
