Among the topics are protecting synchronous generators, using oscillograph
records to analyze system performance, wide-area monitoring and situational awareness, integrating wind power into power systems, and optimal power flow.
2] [micro]g/ml) and increasing concentrations (200, 400, 800 and 1200 mg/ml) of the extract prepared in distilled water, were tested and the results were recorded on a Harvard Universal Oscillograph
with the help of an isotonic T2 transducer.
The Swedish artist Carl Michael von Hausswolff applied his sound experiments as a kind of acoustic security camera: He added sound recorders to the building's electrical grid, transforming the electrical current into noises whose frequencies appear on an oscillograph
as a greenish force field.
With the use of a vacuum tube amplifier and oscillograph
he measured changes in potential at the skin surface.
74) While a tone, for example, can be visualized by an oscillograph
or an electronic oscilloscope, the image is not an akoumenon because such an electronic reproduction does not capture the original expression of energy exchange, that is, it cannot reproduce the original and unique cue of that particular tone.
