Testing an Impedance Non-destructive Method to Evaluate Steel-Fiber Concrete Samples
(Institute of Measurement Science of Slovak Academy of Sciences, 2018-03-01)
The paper discusses tests related to the evaluation of the density and orientation of fibers in a composite material. Compared to the approaches used to date, the proposed technique is based on the evaluation of the ...
A Non-Destructive Impedance Method Using Resonance to Evaluate the Concentration of Steel Fibers in Concrete
(De Gruyter, 2018-10-08)
Steel-fiber reinforced concrete is a composite material characterized by outstanding tensile properties and resistance to cracking. The concrete, however, exhibits such characteristics only on the condition that the steel ...
A Sensor System for Detecting and Localizing Partial Discharges in Power Transformers with Improved Immunity to Interferences
The paper reports on the solution, principles, and application results related to a system for diagnosing main transformers in power plants via the radiofrequency method. The subject of the diagnostics is the occurrence ...
