(I) Performance characterization of Sensata Modular Contactors (SMC600) through the following tests:• Manual Pick-up Current | Measurement of current at which contactor coil MMF overcomes return spring force and movable contact is fully seated on stationary terminals. • Terminal Current Characterization | Validation of contactor thermal endurance through application of 600A current at 85C ambient temperature for 8 hours inside a Powered Thermal Cycle Endurance (PTCE) chamber.• HIPOT Test | Validation of insulation resistance through application of high potential difference across various insulating parts.• Levitation Test | Determining the minimum terminal current at which the movable contact undergoes levitation by applying pulsed currents over 5kA within 5ms using a 24V load bank.• Force versus travel test | Measurement of the force required to compress the contactor’s plunger return spring and corresponding displacement of plunger using Starrett single-column force measurement system. (II) Collaborated with the company’s senior engineers to debug and replace damaged parts on a 1500V load bank capable of supplying up to 25kA current so that it can be used to perform short circuit experiments contactors and fuses.Documented procedures on various SMC600 characterization tests.Prepared reports on SMC600 characterization tests.Tools and programming usage: Benchtop Instruments, MATLAB, MS Word, MS Excel.
