摘要: 在脉冲供电和正弦交流供电地电阻率观测研究中, 大地容性效应会引起测量误差。 本文按照电子学等效电路的方法提出了大地等效电容量的概念, 研究了大地等效电容量的测量方法, 为合理确定脉冲供电参数和减小交流地电阻率测量误差奠定了基础。

Abstract: Earth resistivity observation is from the DC power supply to more powerful pulse power supply with sinusoidal AC power supply, but the earth capacitive effects will cause observation error. This paper analyzes the effects of earth capacitance from the supply perspective. According to the method of equivalent circuit electronics, I put forward the concept of the equivalent capacitance of the earth. The relationship between equivalent capacitance of the earth and frequency and polar distance has been found based on experiment observations.

Key words: Equivalent capacitance of the earth, Resonance method, Alternating current injection method
