Oil cooled power transformer has important role in the electricity distribution system. Its windings were immersed in oil as an insulating medium and also as a cooler. This oil would be heated up due to several things, the most significant was heat generated by winding’s power loss. The monitoring of oil temperature on the transformer was always done routinely every day to maintain its performance and health condition. IoT based measurements could improved efficiency and minimized manpower resources. To realize this the indirect non-destructive measurement method was proposed to estimate transformator’s temperature oil. It will corellate the oil temperature and body temperature through a constant calibration factor derived from calculations. Conducted experiment applied to specific existing transformator and followed by calculations resulted a calibration factor = 1.7749. The smallest average of estimated temperature error was lied in the range of 40 - 90 degrees Celcius.

Abstract. The development of a non- destructive measurement method for ion beam parameters has been treated in various projects. Although results are promising, the high complexity of beam dynamics has made it impossible to implement a real time process control up to now. In this paper we will propose analysing methods based on the dynamics of Cellular Nonlinear Networks (CNN) that can be implemented on pixel parallel CNN based architectures and yield satisfying results even at low resolutions.

It discusses the measurement principle and the system design of 3D non-destructive measurement method for the homogeneous entity. The measurement project and its operating process is discussed. The basic operation principle and components of this measurement device are pointed out. It included the digitized minute entity cells and the delaminated measuring method for product profiles based on liquid. It is based on Archimedes' principle and lever principle and gravity moment, combined the equations of the gravity moment and the equations of the center of gravity, the 3D coordinate values of every minute entity cell in different layers can be reckon by computer. By inputting the 3D coordinate values of the product into the related CAD software system, the 3D model could be obtained. The principles, the system software were introduced in details about the measurement system of the homogeneous entity profiles. Proved through principium experiment, the system satisfies the request of the measuring precision. The measurement system is effective and feasible.
