Test Strategies for Multi-Voltage Designs [PDF]

, 2009
Reducing the power consumption of digital designs through the use of more than one Vdd value (Multi-Voltage) is known and well practiced. Some manufacturing defects have Vdd-dependency, which implies defects can become active only at certain power supply

Reliability modeling of high-voltage power lines in a sharply continental climate [PDF]

E3S Web of Conferences, 2020
One of the important elements of the high-voltage transmission line is 110 kV, the damage of which leads to under-supply of electricity, i.e. reducing the reliability of the lines.

ADULT CANCERS NEAR HIGH-VOLTAGE OVERHEAD POWER LINES

ISEE Conference Abstracts, 2013
Extremely low-frequency magnetic fields are designated as possibly carcinogenic in humans, based on an epidemiologic association with childhood leukemia. Evidence for associations with adult cancers is weaker and inconsistent.We conducted a case-control study to investigate risks of adult cancers in relation to distance and extremely low-frequency ...

Air ion concentrations under overhead high-voltage transmission lines [PDF]

, 2008
This paper reports air ion concentration monitored at 41 sites under overhead high voltage ac power lines in and around an urban environment. The net ionic polarity under power lines was of both signs but mostly positive, and concentrations varied widely

Communication Characteristics of Faulted Overhead High Voltage Power Lines at Low Radio Frequencies

Energies, 2017
This paper derives a model of high-voltage overhead power line under fault conditions at low radio frequencies. The derived model is essential for design of communication systems to reliably transfer information over high voltage power lines. In addition,

Oxidation Stability of SiO₂ and TiO₂ Nanofluids for High Voltage Insulation

Applied Sciences
Mineral oils are increasingly being replaced by plant-based insulating liquids, known as natural esters, because of their biodegradability and high fire safety characteristic. However, their wider use in high-voltage and unsealed transformer applications
