Comparative High Voltage Impulse Measurement
A facility has been developed for the determination of the ratio of pulse high voltage dividers over the range from 10 kV to 300 kV using comparative techniques with Kerr electro-optic voltage measurement systems and reference resistive voltage dividers. Pulse voltage ratios of test dividers can be determined with relative expanded uncertainties of 0.4 % (coverage factor k = 2 and thus a two st...
متن کاملOptical high voltage measurement transformer using white light interferometry
A new approach to perform measurement of potentials in high voltage levels using electrooptical Pockels sensors is presented here. This paper describes an application of the White Light Interferometry technique to a high voltage optical fiber measurement system. In this system the information is encoded in the spectrum of the light, allowing the measurement to be independent of the optical powe...
متن کاملMeasurement of Partial Discharges in High Voltage Equipment
In this thesis I investigate the possibility of electrically detecting partial discharges in high voltage equipment. Partial discharges are small events that occur in insulation in the presence of high electric field intensity and manifest themselves as pulses of current superimposed on the high voltage lines. They carry important information about the condition and operation of such equipment....
متن کاملMeasurement of the Magnetic Fields from High-Voltage (230 kV) Substations in Tehran and Assessment of Their Effects
Introduction: Recent industrial developments in human societies have caused rapid advancements in technologies of production and distribution of electricity, which in turn result in enhancement of power networks and utilization of high voltages. These networks and the high voltages in transfer lines cause the exposure to electric and magnetic fields. In this study, the situation regarding the m...
متن کاملTopologically dependent voltage measurement
In many cases the electric field is the gradient of a potential. In those cases a measured voltage is completely determined by the points connected to the measuring device. But if the curl of the electric field vector is non-vanishing (i.e. the magnetic field is time-dependent), a measured voltage may depend on the topology of the circuit. This effect was discussed in articles by Romer (1982), ...
