This paper describes the analysis of the over voltage phenomena at the motor terminal of an inverter fed induction motor. The high frequency model for a three phase cable and induction motor is simulated using Simulink and analyzed for the over voltage for different cable length. The results indicate that the over voltage is a function of cable length and it also depends on gauge of the cable.

this paper presents an investigation on the effect of temperature and raw material on microstructure of fine cellular foam used as the insulation of coaxial cables. a set up was prepared and used to produce fine cellular foamed insulation. as the physical  blowing agent, butane was used. the effect of temperature on the microstructure of polyethylene (pe) was worth to note. at high temperature,...

Nowadays, the export volume of copper concentrate from Republic Armenia equals more than 500 thousand tons per year. This extent fully satisfies minimum requirements for constructing a smelter in our country. Calculations show that production capacity is estimated 120 Although it considered to be modest result context mining scale worldwide, significant importance The and pure will contribute f...

Due to short product life cycles, increasing variety of products and short cycles of leap innovations manufacturing companies have to increase the flexibility of factory structures. Flexibility of factory structures is based on defined factory planning processes in which product, process and resource data of various partial domains have to be considered. Thus factory planning processes can be c...

In the referenced paper [ 11, the author examines the stability of the planar, linear response of a suspended cable subjected to harmonic axial loading. The study is motivated by a desire to understand the dynamic stability of cables employed in structures such as cablestayed bridges or guy-towers. In these applications, the harmonic axial load derives from the dynamic reaction of the structure...

Seafloor observation system using the underwater telecommunication cable is one of the most reliable ways to secure high-speed data transmission and continuous power feeding to underwater devices. In this paper a new scientific submarine cable system will be presented that were proposed by the technical committee organized by IEEE OES (Institute of Electrical and Electronics Engineers, Oceanic ...

Cable modems based on Data-Over-Cable Service Interface Specifications (DOCSIS) provide broadband Internet access to over one hundred million users worldwide. In some cases, the cable modem connection is the bottleneck (lowest speed) link between the customer and the Internet. As a result, the impact of buffering and bufferbloat in the cable modem can have a significant effect on user experienc...

ABSTRACT: An intensive research work is carried out to determine the effect of humidity and contamination on cable termination and it’s aging. In this paper, the effect of atmospheric conditions on cable termination has been investigated by measurement of discharge inception voltage, discharge magnitude, dielectric loss and capacitance of each phase of cable. The three possible conditions i.e n...

A method for forecasting the outage frequency of cable sections including the influence of repair-joint increase is presented. Time series of joint numbers are processed by a computation procedure applying aging models for cable sections and joints. The methods were tested using data of a real-life medium voltage cable network. It could be shown that outage frequency of cable sections can be su...
