The second generation of Very-High Speed Digital Subscriber Lines (VDSL2) represents a modern high-speed solution for present last-mile access networks. However, the transmission performance of VDSL2 lines is heavily dependent on the real conditions of symmetrical pairs and quads in local metallic lines and cables. One of the frequent elements in metallic access networks, which can negatively i...

This paper analyzes the effect of sliding speed on electrical conductivity and friction properties contact pair an on-load tap changer (OLTC). Reciprocating current-carrying tribological tests were carried out a rod–plate–copper–tin–copper galvanic couple at different speeds in air insulating oil media. The results show that as increases from 24 mm/s to 119 mm/s, average resistance 0.2 ? 0.276 ...

The increasing Photovoltaic (PV) penetration in residential Low Voltage (LV) networks is likely to result a voltage rise problem. One of the potential solutions deal with this problem adopt distribution transformer fitted an On-Load Tap Changer (OLTC). control OLTC response local measurements reduces need for expensive communication channels and remote measuring devices. However, requires devel...

Electricity Distributions Networks (DNs) are changing from a once passive to an active electric power system element. This change, driven by several European Commission Directives and Regulations in the energy sector prompts proliferated integration of new network elements, which can actively participate operations if adequately utilized. paper addresses possibility using these DN elements for ...

Power transformers being the major apparatus in a power system, thus the assessment of transformer operating condition and lifespan have obtained crucial significance in latest years. Dissolved gas analysis (DGA) is a sensitive and reliable technique for the detection of incipient fault condition within oil-immersed transformers, which provides the basis of diagnostic evaluation of equipment he...
