Analysis of statistical processing of thermovision tests' data
The paper presents the results of the thermovision tests' statistical data processing of electric equipment high-voltage (110-330 kV) contacts. It has been shown that modern technologies of thermovision control testing allow to get data which help to obtain exploitation indicators of the reliability after corresponding statistical processing. The possibilities of some methods have been considered using the data from "Kolenergo".

Evaluation of wind loading influence thermographic diagnostics of energetics objects
Laboratory investigations and experiments on solvent extraction of tantalum from fluoride-sulphuric acid solutions using octanol-1 have been presented. Conditions for precipitating high-purity potassium heptafluorotantalate (PFT) from tantalum re-extracts have been determined. A flowsheet has been developed for the processing of metallic tantalum-bearing wastes with the production of PFT, with optimal regimes for individual process stages. The 500 kg of high-quality PFT accumulated during the testing have been used to produce high-capacity, high-quality tantalum powders for advanced capacitor making.

Estimation of indicators of ship electrical equipment reliability, influence on the marine safety and probability of insurance risks
The authors present the calculation of electrical equipment reliability using the data of IR-thermography diagnostic of various vessels in different dates. The indicators of ships operation efficiency and safety depend essentially on reliability. Application of technical diagnostic's systems allows preventing or substantially reducing the number of ship equipment failures, forced stop at sea, and therefore the number of insurance cases.
