Sergio Feitoza created Cognitor Consulting, Technological Research & Training in 1996. Cognitor apply training and consulting on design, specification and testing of equipment for substations (switchgear, switchboards, busbar systems, busways and others).
We also design testing laboratories (high-power, high voltage, temperature rise, electromagnetic compatibility and Ex equipment). Training and consultancy work can be applied in English, Portuguese and Spanish in all countries.
Sergio Feitoza is an electrical engineer, M.Sc. in Power Systems and Director of Cognitor. He has 35 years of experience in high power and high voltage testing laboratories (design, construction, operation as test engineer and management), substations equipment design and testing.
In the 25 years working at CEPEL he participated in all the phases of the design, construction and operation of the testing laboratories in Brazil. He was the manager of (14) laboratories including high voltage, high power, Ex equipment, EMC, materials and calibration. Also, chaired teams in renewable and nonrenewable energy generation.
In 2010 Sergio developed the feasibility study for a new Brazilian testing laboratory, now under construction, in Itajubá - MG. These are installations for high power testing (2500 MVA with short circuit generators), high voltage testing (550 kV class), temperature rise tests (25 kA) and others. From 2012 Sergio is contracted as consultant by the owners of the project ISI-CEDIIEE.
TESTING SIMULATIONS, DEVELOPMENT OF EQUIPMENT FOR SUBSTATIONS & R&D
In the last 19 years conducting Cognitor activities Sergio acquired a considerable experience in the simulation of high power tests developing and applying the software SwitchgearDesign (details in this site). He provides consulting services to manufacturers in developing products for substations, specially switchgear, switchboards and busways. The idea is that before going to a testing laboratory to do expensive type tests, the manufacturer send the basic drawings to Cognitor which, through the simulation of the tests using SwitchgearDesign and a long term experience in designing equipment, helps to improve the project to pass in the tests.
TRAINING ACTIVITIES AND PUBLICATIONS
Training: more than 200 courses and seminars, open and "in company" all over the World (in English, Spanish, Portuguese). Some free material for download may be found in this YouTube link:
