This paper discusses data acquisition, transmission and processing methodologies for continuous on-line monitoring of partial discharges in high voltage cable systems. A PD continuous on-line monitoring system for underground cable circuits using capacitive couplers, LiNbO3 electro-optic modulators, laser, optical switch and optical fibers has been developed. Future research will consider effec...

Increasing deployment of digital subscriber line (DSL) technology operating in the long wave, medium wave and sometimes short wave frequency ranges, has raised the question of how such systems interact with rival radio frequency sources and equipment. Two of the major standards bodies in the field, ITU and ETSI, imposed by the standardization of such promising technologies like ADSL, SHDSL and ...

Considering an environment containing polygonal obstacles, we address the problem of planning motions for a pair planar robots connected to one another via cable limited length. Much like prior problems with single robot fixed base, straight line-of-sight visibility plays important role. The present paper shows how reduced graph provides natural discretization and captures essential topological...

this paper presents novel active filter for mitigation electromagnetic interference (emi) and other adverse effects of pulse width modulation (pwm) inverter-fed ac motor system. an active filter proposed and devised for this system is characterized by sophisticated connection of two small separate filters, capable of mitigating all the adverse effects. this paper provides high frequency models ...

Measurement of static electricity is of critical importance in assessing the proper electric properties of car seat covers and their suitability to be used in application to enhance the safety and stability of the driver. The present work aims to measure the static electric charge generated from the contact and separation of materials used as car seat covers and clothes. Different materials of ...

When submarine cable line fails or other lines need load transfer, it often suffers from emergency ampacity that exceeds the steady-state ampacity. The layout environment of is always complex and changeable, overload capacity in different environments also different. Therefore, necessary to analyze cable. In this paper, a coupled multi-physical field model by finite element method established f...

In order to study the failure mechanism of high-voltage cable buffer layer caused by moisture and performance material after immersion drying, according structure size 110 kV XLPE cable, requirements for separation distance between corrugated aluminum sheath insulating outer shield before change resistivity were calculated, influence on ablation was analyzed. The test platform built, properties...
