This paper aims to develop a comprehensive model of a magnetic sensor array that will be operational for a multitude of electric components in continuous and nonintrusive condition monitoring (CM) or in readiness assessment (RA) applications.

A universal nonintrusive model of a flexible antenna array is introduced to monitor and identify failures in electric machine drives. An adjustable sensor is designed to serve as a RA for a vast range of electrical elements in a typical power system by capturing the low-frequency radiated magnetic fields.

The optimal placement of the most sensitive radiated fields from several components has been discovered in this case study, enabling the detection of healthy current flow throughout. Thereafter, the short-circuit investigation, representing faulty situations, is implemented and compared with healthy cases.

This sensing technique can be used for nonintrusive CM of components that are out of reach and cannot have the sensor to be held around it such as components in offshore winds, wind energy generation and power and chemical plants.

The results are provided for three commonly used machines with a single sensor array with numerous settings. The three dimensional (3 D) finite element analysis is applied in the structuring of the sensor, detection of the optimum location and recognition of faults in the machines. Finally, based on the setup design, 3 D printing is used for the construction of the sensor array. Thus, the sensor array with fault detection avoids major component failures and increases system reliability/resiliency.

In this paper, modeling of the XLPE cable for electromagnetic signature study at a far distance is proposed. The paper aims to discuss these issues.

Due to the very small ratio of the dimensions of cables to the dimensions of the whole system, using actual geometry of the cables with all layers in this study causes deformation of the cable's model. Therefore, multi-dipole modeling is used for modeling the cables.

This model includes specific voltages and currents in lines and nodes, respectively. Radiated electric and magnetic fields at a far distance are selected as the index of appropriateness of the model.

In order to investigate the accuracy of the model, various configuration of the cable is studied. Additionally, coupling of the cable with an electrical machine is investigated. They all show that the equivalent models can be used in place of the actual model for signature studies.
