[IEEE 2018 Conference on Precision Electromagnetic Measurements (CPEM 2018) - Paris, France (2018.7.8-2018.7.13)] 2018 Conference on Precision Electromagnetic Measurements (CPEM 2018) - Research of the National Primary Standard of the High DC Voltage
摘要: This paper is devoted to the research of the metrological characteristics of the National primary standard of the unit of electrical DC voltage of Ukraine in the range from 1 to 180 kV (NPS). The research has allowed to reduce the step of measuring the DC voltage in the range from 10 kV to 180 kV from 10 kV to 1 kV and to reduce the standard uncertainty of the measurement of the high voltage at the NPS.

摘要: In this paper, a modification is done in the multipliers resistors of the thermal voltage converters (TVCs) to introduce a more accurate and precise standard for voltages higher than 0.5 V. The modified multiplier value which is designed and implemented at NIS, Egypt is 1 kΩ to cover the voltage range 5 V. The modified multiplier resistor (MMR) is built from ten metal-film resistors connected in series in a radial form. Modified TVC which is made by using this MMR is automatically calibrated at different frequencies. Its behavior is evaluated by the traditional TVC.
