“…Studies on the reliability of optocouplers have been conducted on failure mechanisms, 14,15 analysis of factors affecting the reliability of optocouplers, 16 and reliability prediction without ADT, [17][18][19] Studies of lifetime estimation with ADTs have not been conducted sufficiently except for the following studies. Zhang et al 20 conducted an ADT on optocouplers, where 10 samples were heated in a four-step stress process to four levels of temperatures.…”

Instrumentation and control systems significantly affect the safety and reliability of nuclear power plants. In this study, we analyze the cause of failure of the electronic card constituting the instrumentation and control system as it is the most typical reason for the failure of optocouplers. The lifetime of optocouplers must be predicted accurately to ensure high-reliability nuclear power plants. While acceleration tests have been performed to predict the lifetime of optocouplers more efficiently, it is preferable to perform accelerated degradation tests rather than accelerated life tests. In this paper, accelerated degradation tests are performed on optocouplers at various temperatures and voltages. To derive the degradation curve model of the optocoupler using the results of accelerated degradation tests, we use the most suitable model from OriginLab. The parameter values of the proposed degradation curve model are calculated by applying the Arrhenius model and Weibull distribution, and the lifetime of the optocoupler is estimated by using the proposed degradation curve model.

“…Due to the variety of applications, it is noticeable the necessity of measuring the characteristics of the components of UAVs as well as whole UAVs, in order to assess their suitability for a given purpose [41]- [44]. Despite the abundance of literature on testing of aerospace materials and components [45]- [47], only few works have considered the problems of the UAV testing and of the design optimization for an assigned performance specification [48]- [51] and fewer have described also the measurement system [52], which is, instead, the focus of this paper.…”

Abstract-The project proposed in this paper deals with the design and the development of an embedded test system able to characterize both electrical and mechanical performances of UAVs (Unmanned Aerial Vehicles) propulsion subsystems (motor and propeller). The measurement data that can be collected are of great interest for professional applications, as well as for amateur makers.Starting from the measures acquired by the presented system, it will be possible to deliver certificates that guarantee the customer that the performances obtained by the drone are compliant to what declared by the seller.
