Loftness, . AC Power Interference Handbook – Insights into the Causes, Effects, Locating, and Correcting of Power-Line and Other Electrical Interference, 3rd E. American Radio Relay League, 2007, 298 pp (ISBN: 978-63760-3-7). The author solved powerline interference problems for electric utilities throughout his career and is quite knowledgeable. He used custom-made and specialized equipment in his work but his methods are well-described and useful to anybody, and he provides many drawings and photographs

Locating Power Line Noise Using TV Waveforms. The author describes a valuable technique for locating and tracking power-line noise. Marv Loftness, KB7KK. caused by electrical noise sources, both power line and off power line arcing sources, and the observations led to a. real breakthrough for noise-locating- although I didn’t realize it at the time. When I first observed the phenomena, I wondered why there were a number of sharp spikes during each half cycle rather. so the resultant beat frequency with the al-most identical 60 Hz power line sine wave causes the power line noise to slowly drift through the TV waveform at a . 6 Hz rate. The TV waveform sync pulses ensure good oscilloscope synchronization and the lock to the TV waveform makes noise observa-tion easy. 2The visble high voltage discharge or arc is actually a plasma-essentially a stream of ionized ai.

Electromagnetic Interference Causes Effects & Miti. The paper enumerates the causes and sources of EMI as well as its disruptive effects on systems such as Global Positioning Systems, aircraft and medical devices. Various means of mitigating the effects of EMI or protecting equipment against EMI are also discussed. an effective way to eliminate interference is by identifying EMI sources and eliminating them. most of which have been recommended for medical equipment. an effective way to minimize or eliminate EMI is to shield vulnerable victims from EMI.
Brownouts and blackouts. Electrical Fast Transitions (EFT). Electrical noise superimposed on the mains power line. These power quality degradation factors can occur simultaneously or independently, during any time interval. 4) Railroad and Mass Transit Systems have some unique types of EMI source problems. These include: Propulsion system’s high voltage and high current operational mode emissions. 2) High Powered Electromagnetic Pulse effects – High powered electromagnetic sources can totally destroy an electrical and electronic equipment’s function. As an example, an HNEMP device detonation above the earth’s atmosphere of the United States can totally immobilize the whole of the continental United State’s infrastructure. IEMI, HPM, E-Bombs, and EMP Cannons can be utilized to disable electronic systems at specific locations.
