Fixed site monitoring of potential gradient fluctuations near to AC high voltage power lines

Adult cancers near high-voltage overhead power lines.

BACKGROUND 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. METHODS We conducted a case-control study to investigate risks of adult cancers in relation to distance and extremely low-frequency magnetic fields from high...

Radiofrequency exposure near high-voltage lines.

Many epidemiologic studies suggest a relationship between incidence of diseases like cancer and leukemia and exposure to 50/60 Hz magnetic fields. Some studies suggest a relationship between leukemia incidence in populations residing near high-voltage lines and the distance to these lines. Other epidemiologic studies suggest a relationship between leukemia incidence and exposure to 50/60 Hz mag...

Conductor Corona Noise Prediction on High Voltage Ac Lines

The conductor corona noise of four local 400 kV AC transmission lines is measured and compared to predictions. The prediction software developed is based on the EPRI semi-analytical approach using excitation functions and the theory of natural modes. The nature and accuracy of the prediction software is discussed along with relevant corona noise metrology issues encountered.

Return to Session THE USE OF INSULATED WIRES MILLIKEN CONDUCTORS IN HIGH VOLTAGE POWER TRANSMISSION UNDERGROUND AC LINES

These last years have pointed out a significant increase of the power that needs to be transported by underground power cables. As a consequence, large cross section conductors, up to 2500mm2 are now customarily used. The CIGRE group B1-03 has completed in 2005 a work that analyses the actual AC resistance of these large cross section conductors as a function of their design. The authors discus...
