  Types. Electromagnetic interference can be categorized as follows: narrowband EMI or RFI, which typically emanates from intended transmissions such as radio and TV stations or mobile phones; broadband EMI or RFI, which is unintentional radiation from sources such as electric power transmission lines.; Conducted electromagnetic interference is caused by the physical contact of . A method for calculating wide band electromagnetic interference from power line corona Article (PDF Available) in IEEE Transactions on Power Delivery 10(3) - August with Reads.   A corona discharge is an electrical discharge caused by the ionization of a fluid such as air surrounding a conductor carrying a high voltage. It represents a local region where the air (or other fluid) has undergone electrical breakdown and become conductive, allowing charge to continuously leak off the conductor into the air. A corona occurs at locations where the strength of the electric. Radio noise interference and corona power losses have been exten­ sively investigated in the field and laboratories [6, 9, 10, 16, 17, ]. Some theoretical analysis has been used to calculate the radio noise and corona power loss on high voltage transmission lines [7, 8, ]. Many approaches to analyze radio frequency interference were.

E., A Practical Handbook for Location and Prevention of Radio Interference from Overhead Power Lines, Naval Civil Engineering Laboratory, Port Hueneme, CA, October An algorithm for calculating electromagnetic interference from power line corona for a range of frequencies from kHz to 30 MHz is demonstrated. It can be used for calculations at any distance.

As described by Pakala and Chartier () power lines are divided into two classes with respect to radio noise: (1) lines with voltages below 70 kV and (2) lines with voltages above kV. Lines in the first class in general exhibit only gap-type discharges and lines in the second class principally exhibit corona discharge. Gap-type.

T. Williams, in Instrumentation Reference Book (Fourth Edition), Electromagnetic interference (EMI) is a serious and increasing form of environmental pollution. Its effects range from minor annoyances due to crackles on broadcast reception to potentially fatal accidents due to corruption of safety-critical control systems. Electromagnetic radiation from power transmission lines can influence the electronic devices nearby due to the corona discharge. A numerical method is proposed to predict the radio interference based on the multi-conductor transmission lines mode and dipole mode. Finally some transmission line . Sheikh, A. U.

When the interference goes away, you've found the "culprit." Your electric utility company service department will offer assistance if the interference is coming from defective equipment on the power lines or distribution equipment. Interference filters for your consumer electronics equipment can be purchased locally or by mail order.
