Currents of contact welding in a static layout: A laboratory exercise

The purpose of the proposed course is to enhance students’ knowledge, engineering skills and understanding in the field of electrical contacts power engineering – the currents of contact welding. The main goal for students is to acquire brief skills concerning measurements of certain parameters using static layout: currents that cause contact welding, clamping force of contacts joints and breaking force. Moreover, students are encouraged to obtain soft skills like confidence in the mentioned field and creativity. Student work during the exercise is evaluated on the basis of report from laboratory work and test. Essential aspect is safety training while working with HV and MV switchgears – that is another obligatory feature which participants will obtain from this course. Course results were evaluated as significant on the basis of concluded statistical analysis and comparison to previous formula employed during the classes.
