Measurements of Shape Memory Alloy actuator for a self-switching electrical fuse

This paper describes chosen results of the measurements of various characteristics of Shape Memory Alloy wire in purpose of its usage as an actuator for self-switching electrical fuse. The experiments were performed by talented pupil of secondary school as a research project co-financed by Polish Ministry of Science and Higher Education. Measurement system consisting of power supply unit PSH-3620a and PC computer with running LabVIEW application is used to control the measurement procedures. Program of experiments consists of static measurements (static switching current), dynamic measurements (switching times) and exploitation measurements (switch off time). The paper presents chosen resultant characteristics.
