Inspection of Transformer Mechanical Integrity Using Sweep Frequency Response Method

Power Transformers are the most critical and hig-hcost elements of power network systems. They play an essential role in power transmission to the users. They require continuous and regular monitoring and assessment, in order to increase the power supply reliability and to avoid hazardous breakdowns. The transformer is ordinarily exposed to high current surges in the course of service, mainly due to short circuit, which impacts the mechanical winding formation. The proposed a diagnostic technique, in this paper, performs a sweep frequency response analysis on the inspected transformer. Although it is considered a highly responsive and powerful inspection method, the critical challenge relies in the appropriate interpretation of the measured frequency response, which remains a gray zone left for professional experts to detect the type and location of defects. An experimental setup has been developed for the proposed testing technique and an analytical digital simulation of the built transformer is carried out. The simulation results could detect the defect type and its location in the transformer winding.

Thermoelectric Quality Control of the Application of Heat-Conducting Compound

The article presents the results of experiments to determine the dependence of thermopower on the quality of applying a heat-conducting compound. The data of deposition quality of the heat-conducting compound, which is obtained by thermocouples, coincides with the data, which is obtained using thermopower, but with a slight deviation due to the intrinsic inertia of thermocouples and fluctuations in the ambient temperature. The analysis of the data revealed that the value of the emerging thermopower increases linearly with the deterioration of the quality of the thermal interface application.

Simulation Study of an Ultrasonic Signal Compression

The paper presents three algorithms of an ultrasonic signal compressing. First one is a compression with linear time quantization. Second algorithm of signal compression calculates the rate of signal change and proportionally to it sets the sampling rate. Third algorithm of compression takes some number of random uniformly distributed samples from the original ultrasonic signal. The results of simulations for all three compressing algorithms are presented in the paper. An absolute error and mean square deviations for a wide range of compression ratios are calculated and compared for different compressing algorithms.

Investigation of the Liquid Flow on Rough Surfaces to Solve the Problems of Liquid Penetrant Testing

Cleanliness of the test surface is of particular importance in liquid penetrant testing. The surface cleanliness implies both the quality of surface cleaning from polluting substances, for example, oil, and the quality of its treatment, i.e. surface roughness. The surface roughness parameter increased to more than Rz = 20 μm can lead to unreliable test results since each groove on a rough surface will be a capillary for liquid spreading. Therefore, it will be difficult to completely remove the penetrant from the surface of the test object while removing its excess, which causes an indicator background of the surface and complicates defect detection. The study aims to determine the effect of liquid wettability on liquid penetrant testing results depending on the surface roughness. The paper proposes a mathematical model of liquid spreading on the rough surface depending on physicochemical properties of the liquid itself and material properties of the test object. The numerical modelling of the process is performed. The modelling results are confirmed experimentally, and statistical processing of the experimental results is performed.

Influence of the Insulation Defects Size on the Value of the Wire Capacitance

The study focuses on detection of defects in the single-core electrical wire insulation by changing the linear capacity of the electric wire. Numerical simulation was performed to create defects that are difficult to implement in practice. In the study, models of the following defects were created: local thinning of the wire insulation, eccentricity, foreign inclusion in the wire insulation. During the study, the depth and length of the ‘local thinning’ defect in the wire insulation, the shift of the core center relative to wire the center, length and thickness of the ‘foreign inclusion’ defect were varied. As a result, absolute and relative values of the geometric dimensions of the defects that cause a significant change in the wire capacitance are revealed. A significant deviation of the capacitance is taken at the level of 5% deviation from the nominal value of the capacitance of a defect-free wire in accordance with the requirements of normative and technical documentation and the accuracy of device for in-process testing of the wire capacitance. The paper reports the results of the initial study. Further research is required to increase the reliability of the models used.

New Factors of Reliability of Electric Furnaces for Vermiculite Firing with Mobile Base Plates

The article reviews measures to increase the reliable operation of electric furnaces for vermiculite concentrates firing over the entire period of their existence since 2003. A significant step forward in this research was the find that the implementation of suspended heating systems in the electric modules of furnaces, both types such as modular-triggering furnaces and in furnaces with mobile base plates, where the swelling process of the raw material is carried out during the process of its vibrotransportation in the thermal field of the heating system. The imbalance of inertial loads is an additional factor for reducing of operation reliability in furnaces with mobile base plates. The methods of their balancing, discussed in this research, provide the dynamic balance of all moving parts of these furnace units. A study of analytical models of temperature distribution, carried out in previous researchers of the authors, showed that uniform heating can only be achieved in systems with a variable interval for the placement of heaters. The research results carried out in this work at the accepted values of the minimum and maximum intervals show that, compared to the old systems located on the refractory base of the firing modules, the difference temperature decreases significantly, which proves the effectiveness of this approach.

New Approaches to Stratification of Patients by the Level of Sudden Cardiac Death Risk Using the Data on Energies of Cardiac Micropotentials Obtained by Nanosensor-Based Hardware and Software Complex

The problem of human cardiovascular diseases is one of the critical health problems. The most serious aspect is sudden cardiac death (SCD). A new method and approaches to recording micropotentials by the nanosensor-based hardware and software complex are elaborated for dynamic personalized monitoring of the heart. Tables with data on functioning of the patient’s heart during multiple examinations are automatically generated in one Excel file. The study presents results on cardiac micropotentials in groups 1A—volunteers died from cardiogenic shock, and 1B—volunteers with acute myocardial infarction (AMI) survived. Relative average values of the total energy for all time intervals are given in the following amplitude ranges: (0.5–1.0) µV; (1.1–3.0) µV; (3.1–5.0) µV; (5.1–20.0) µV in a dynamic pattern. The results are divided into 3 ranges: the total energy value of more than 150%, less than 50% and in the range of (50–150)%. The most significant changes in the micropotential energy by a factor of (4, 5) can be observed in the range of (5.1–20) µV. It is shown that the excess of the micropotential energy over 150% and the decrease in the micropotential energy below 50% are predictors of SCD.
