China's IP transmitter employs voltage source power supply but uses a steady flow source supply formula to calculate the polarizability, thus leading to a somewhat lower value, which can not represent the real ground polarization. The authors derived the formula for calculation of voltage source power supply polarizability and, on such a basis, developed the device for the measurement of the change rate of the current. The use of the corrective formula can get the real ground polarizability.
