Operational Monitoring Model of a Hermetic Cable Gland in NPP

Abstract

A practical example of a hermetic cable gland for nuclear power plants is described. A model is constructed for performing diagnostics of the parameters of the hermetic cable gland and a procedure for performing operational monitoring of its state is developed. The proposed device makes it possible to reduce the development risk of emergency situations in the system by increasing the operational reliability of the hermetic cable gland. For this reason, operation monitoring of the electrodynamic state of a hermetic gland in NPP on the basis of an equivalent model is significant and urgent.
