Technical diagnostics of the contactless transformer sensors blocks of geodynamic monitoring system

Monitoring systems of geodynamic objects built on the basis of multi-polar electrolocation equipment are widely used now due to the increased danger of technogenic catastrophes causing instability of geological structures. These systems consist of emitting electrodes and receiving contactless transformer sensors located directly in soil. Characteristics of the block components change over a wide range and sometimes fail due to severe service conditions of the sensors. The purpose of this paper is to develop technical diagnostics subsystem of the contactless transformer sensors blocks, allowing to identify characteristic deviations of block components from operational ones when operating geodynamic monitoring system on the object under control. It is important to identify block component failures transferring data to the central station.
