A novel water resistor divider with a coaxial low-voltage arm

摘要

A new style high voltage resistor divider made of saline solution has been constructed and tested. A coaxial construction is used on the low-voltage arm, as the signal extraction electrode, which can increase the attenuation ratio of the divider. The time response of divider limited by the stray parameter also can be improved. Comparing the results of calibrated experiment with the commonly used equal size copper sulfate dividers, the new probe has nearly five times increase in the attenuation ratio. The time response of the new style divider in the dimension of 30 mm in diameter and 400 mm in length can reach to 1 ns. © 2010 American Institute of Physics Article Outline INTRODUCTION CONSTRUCTION AND PRINCIPLES OF OPERATION OPERATION AND RESPONSE CHARACTERISTICS Rise time response test Attenuation ratio comparison with the usually used water-resistor divider CONCLUSION
