Inactivating microorganisms using a pulsed electric field continuous treatment system

- B. Qin, G. Barbosa-Cánovas, B. Swanson, P. Pedrow, R. Olsen
- Engineering
- 1998

High-voltage pulsed electric fields (PEFs) can be used to inactivate microorganisms in liquids. Applying PEF technology to food pasteurization is a promising nonthermal method, which may radically… Expand

A comparison of exact and quasi-static methods for evaluating grounding systems at high frequencies

Recently, it has been suggested that traditional quasi-static methods for evaluating power network grounding systems are not valid at high frequencies. However, the conditions under which exact full… Expand

Magnetic fields from electric power lines: theory and comparison to measurements

- R. Olsen, D. Deno, +8 authors R. Zavadil
- Engineering
- 1 October 1988

It is shown that currents and magnetic fields should be described statistically, because load currents fluctuate considerably during the day. The source currents include both the current in all power… Expand

Electromagnetic wave propagation on a thin wire above earth

The electromagnetic properties of a current on a thin horizontal wire above a flat lossy earth is reviewed. Attention is given to the historical development of the topic, starting with the seminal… Expand

On the Exact, Carson and Image Theories for Wires at or Above the Earth's Interface

- R. Olsen, T. A. Pankaskie
- Physics
- IEEE Power Engineering Review
- 1 April 1983

The relation between the exact theory and Carson's theory for the fields of straight wires above a homogeneous earth is derived. Sufficient conditions for the validity of Carson's equations are… Expand

Characteristics of low frequency electric and magnetic fields in the vicinity of electric power lines

The authors describe the quasi-static and radiation fields of simple three-dimensional sources and proceed to a two-dimensional source. It is shown that the quasi-static approximations result in an… Expand

Inaccuracies in numerical calculation of scattering near natural frequencies of penetrable objects

- G. L. Hower, R. Olsen, J. Earls, J. Schneider
- Physics
- 1 July 1993

Calculated scattering from a nonconducting cylindrical ring shows great variability with small changes in the material or geometric parameters within certain ranges of these parameters. The… Expand

A New Method for Real-Time Monitoring of High-Voltage Transmission Line Conductor Sag

- R. Olsen, K. S. Edwards
- Engineering
- IEEE Power Engineering Review
- 14 October 2003

The amount of power flowing through a high-voltage transmission line is proportional to its voltage and the current flowing through it. To increase power flow without modifying the line to allow… Expand

Application of a corona onset criterion to calculation of corona onset voltage of stranded conductors

- K. Yamazaki, R. Olsen
- Materials Science
- IEEE Transactions on Dielectrics and Electrical…
- 24 August 2004

The conditions under which corona first occurs for any set of electrodes are an important design consideration since corona can limit the performance of any given configuration of electrical… Expand
