“…One of the effective methods of increasing the sensitivity is the use of multidimensional (multiparameter) RP based on the information approach [1][2][3][4]. There are developments of multiparameter protection, for example, for solving problems of longdistance backup with SC behind a transformer [5], as well as for determining the response parameters and combining the signals of individual starting organs [6][7][8].…”

“…The use of microprocessor technology in RP devices provides the flexibility and versatility of their work. One of the modern directions in the evolution of RP is the development of multiparameter (multidimensional) algorithms [1][2][3][4][5][6]. Their basis is the use of multiple parameters of measured currents and voltages in the recognition of the operation modes of the electrical network.…”

The features of the dielectric rod defects and the rod-electrod defects of polymer insulators were investigated by using the developed complex method of contactless remote diagnostics of high-voltage insulators health, which includes the initial detection of local areas with elevated electric field gradients as well as measurement of a set of partial discharges characteristics. The radiation of extra-large partial discharges was detected and partial discharges features were investigated. According to the measurement results, a diagram was constructed for the electro-physical processes that accompany the emission of extralarge partial discharges; and the reasons for their occurrence were established. Statement of the taskThe use of the information approach in RP involves the multiple implementation of simulation of the electrical network and the protected object in normal and
