Influence of the Position of the Electrical Contact on the Size of the Temperature Distribution

Published by Dušan MEDVEĎ1, Ján ZBOJOVSKÝ2, Technical University of Košice. ORCID: 1. 0000-0002-8386-0000; 2. 0000-0003-4383-3996 Abstract. This paper deals with the investigation of temperature field distribution around the high-current electric contact. The analyses of temperature field were realised in simulation environment ANSYS and provide better understanding why the electrical contact position influences the heat dissipation.Continue reading “Influence of the Position of the Electrical Contact on the Size of the Temperature Distribution”

What is Contact Resistance Test and Why is Contact Resistance Testing Done

Published by Carelabs (Carelabz), Website: carelabz.com What is Contact Resistance Contact resistance is the resistance to current flow, due to surface conditions and other causes, when contacts are touching one another (in the closed condition of the device). This can occur between contacts of:  Breakers  Contactors  Relays  Switches  Connectors  Other switching devices  Contact resistance testing alsoContinue reading “What is Contact Resistance Test and Why is Contact Resistance Testing Done”
