A group made, first of all, of people passionate for rotating electrical machines and electronics, who our customers can talk and interface with, to come to one single goal always standing by our customers: the development of solutions. Today, our journey keeps on in an increasingly dynamic market, where challenges are travel companions and ...
The instrument, called Shaft Current and Voltage Protection Relay (SCVP) was developed at KONCAR – Electric Engineering Institute Inc. This instrument is a part of Institute's product line used for monitoring and diagnosis of rotating electrical machines. The most important parts of every electric power ...
But Sulzer’s offering goes even beyond electrical repairs and upgrades of rotating machines. When Melbourne needed new impedance bonds for an improvement of its rail network infrastructure, the Sulzer team took up the challenge. ...
This paper evaluates the bearing fault severity in rotating electric machines based on the time–based descriptors derived from machine vibration signal. Time–based descriptors are independent of bearing dimensions and machine dynamics. To establish the relationship between the time–based descriptor and bearing ...
Abstract This article describes a specific instrument for detection of excitation winding shorted turns in hydro generators, developed in Koncar - Electrical Engineering Institute Inc., called Hydro generator Winding Fault Detection (HO WFD). This instrument is a part of the Institute's product line used for monitoring and diagnosis of rotating ...
Copper cable granulator, also named scrap wire recycling equipment, is a machine used for crushing copper scrap and later separating copper from the plastic. ...
Abstract Detection of inter-coil short circuits has a significant importance in nowadays diagnostics of rotating electrical machines. In this paper two modern, reliable and economically viable methods for such detection in excitation windings of turbo generator have been described. ...
One of the most common root causes of failure of rotating electrical machines is bearing failure; but the failure mode that has the greatest impact, with regards to downtime and lost production, is failure of the stator winding insulation, particularly in highvoltage machines. ...
