摘要： Systems and methods for measuring the integrity of insulation components in electrical systems. In preferred embodiments, an active sensor is coupled to a test tap of a bushing, the active sensor having an electrical circuit electrically coupled to the test tap, and wherein the electrical circuit includes a high pass filter that divides the electrical circuit into a high frequency bus and a power frequency bus. A grounded high frequency voltage is injected into the test tap via the frequency bus circuit. Resulting voltages and currents may be measured and compared to a reference voltage to determine capacitances and power factors for both the inner and outer sections of the bushing. Once the capacitances and power factors of the bushings are known, grounded and ungrounded high frequency voltages may be injected to determine capacitances and power factors of a connected transformer or reactor.

摘要： A fluid contamination analyzer (90) accepts data from a sensor array (94). The fluid is affected by a magnetic field stimulus (96) from a control driver (98). Alternatively, an electrostatic field exciter may be used. The sensors impedance as a function of field strength is an indication of the particles characteristics, when multiple sensors are separated by substantial distances, a system of communication links is used and the information is digested at a central location.

摘要： Pictorial images of selected volume elements of materials are generated by a contactless, non-destructive, susbstantially hazardfree tomographic technique in which the material is brought within the influence of a relatively lowstrength electromagnetic field and subjected to plural preselected frequencies to provide output data which is used to generate an image reflective of the magnetic and/ or electric and/or conductance properties of the selected volume elements. This data has a high volume information content which enables accurate and reproducible identification of the material under investigation. The technique has application in the medical diagnostic field such as for example in aiding in the detection of small areas of cancerous tissue present in a larger mass of healthy tissue.
