To harvest the generated power, the turbines of an offshore wind farm are connected to an electrical transformer by cable routes. Typical cable layouts use two cable types distinguished by price and capacity: High capacity is expensive. This work presents a heuristic for computing near-optimal layouts based on the Clarke and Wright savings heuristic for vehicle routing, and the layouts it compu...

The ideal transmission cable exhibits little parasitic capacitance between individual internal cable conductors and also between the conductors and the cable shielding. However, transmission cables possessing high parasitic capacitance are becoming increasingly common in the glass coating industry. Cables designed for increased flexibility and reduced costs often provide minimal spacing between...

Incipient faults usually emerge from partial discharges which eventually cause insulation degradation between two insulated cable cores. Early detection of incipient faults is of particular importance because insulation defects caused by incipient faults may lead to permanent faults in underground distribution networks. This paper presents a novel approach using S-transform and support vector r...

Power cables behave as transmission lines as regards partial discharge (PD) pulse propagation. Attenuation and dispersion phenomena have, therefore, great influence on the detectability of PD pulses, particularly when long cable routes and detection from terminals are considered. This paper presents an approximate model to infer PD pulse waveform as a function of the distance travelled along th...

The article describes a way of evaluating the power line channel frequency response and input impedance by means of the linear time-invariant (LTI) power line generator. Two possible methods are introduced for the calculation of primary parameters: the first method depends on the physical realization and physical dimension of the cable, and the second method is derived from the data provided by...

Field Server (FS) is a rugged server which can be installed in fields. Field Monitoring Server (FMS) is a kind of FS for monitoring. So far, solar cell embedded on the top of FMSs have been used only as a light intensity sensors. The power source for FMS is supplied by a cable, since the solar cell's power alone is not sufficient to run conventional FMSs. To construct a massively distributed mo...

In order to carry out the simulation of the electrical noise, a pulse generator with fast rise time is needed. For this reason, the pulse generator using a coaxial cable is usually used. The pulse generator consists of a DC power supply, a charging resistor, a coaxial cable, a relay, and a terminator. Even the same voltage as charge voltage was outputted when the termination of the impedance wa...
