- Abstract:
- The paper deals with problems of very high impedance (|Z| < 10 GΩ) measurements in a wide frequency range (10-5 ... 106 Hz). The measurements are aimed to identify electrical parameters of different anti-corrosion coatings. The construction of the measuring system designed for monitoring the anti-corrosion coatings effectiveness on various types of technical objects is presented. The circuit solutions analysed refer, in particular, to the input adapter, the measuring signal generator, and the phase-sensitive detector. The test results of the whole measuring path are shown and some parameters determining low and high band of the system frequency range are pointed out.
