Abstract
Soil resistivity is measured by resistivity or induced polarization methods. In induced polarization techniques, time domain or frequency domain methods are used. The frequency range of operation is 1-10 Hz. In this paper we have designed a frequency domain induced polarization equipment for 55 v/110 V/220 v range in dc and ac. Frequency selection is done as some cardinal parts 0.1, 1.0, 0.3 and 3.0… up to 10 Hz. The collected data for each of the frequency is used to compute the percentage of frequency effect. The values are to be obtained in different kinds of soil for optimization of frequency. This instrument has wide application in demarcating types of soil/rock for pollution and disaster management studies.
