Summary

Arc faults are caused by loose, damaged, or corroded connections of electrical terminals. These faulty terminal connections cause electrical current to spark or arc, between metal contact points. Terminal arcing generates enough heat to break down the wiring insulation and ignite any surrounding flammable material, which ends up with fires. Since it is not possible to detect arc failures at normal working conditions, an accelerated test is needed to simulate Arc Failures, caused by loose/weak terminal contacts in order to catch these faults before sending them to customer. European Fire academy reported that electrical failures including arc faults account for twenty-five percentage of building fires.
The purpose of this study is Simulation of Arc Failures that occurs in the field because of loose contacts of compressor or refrigerator terminals, and Arcing Test Acceleration in order to distinguish good and weak terminal connections in early stage. To this end, the proper stress factors will be defined, both reliable and faulty terminal samples will be prepared and tested, and Reliability Analysis will be performed in order to verify the obtained results.
As a result of this study, a forced failure test will be put into use and it will be possible to catch weak or loose terminal contacts caused by process faults which will emerge in the field. So that a big safety risk will be minimized on household and similar electrical appliances.
