标题：Analysis of RAM (Reliability, Availability, Maintainability) Production of Electric Voltage from 48 V PV (Photovoltaic) at Pantai Baru Pandansimo, Indonesia
摘要：The production on electrical voltage from photovoltaic has fluctuating performance, so it needs to be maintained with optimum control and operational system. Reliability in operation maintenance needs to be maintained, so that the production of electric voltage can be maintained. The analysis is done by calculating the reliability based on the failure rate ( λ ) that obtained from the value of out of scope contained on the control chart. The variation given is in the form of a failure rate ( λ ) based on the standard deviation limit. The reliability and availability values are obtained based on the failure rate ( λ ) while the maintainability values are obtained from the value of repair ( r ) based on the results of an interview. The failure rate ( λ ) obtained has a constant value of 0.0274. The reliability value of the photovoltaic system has decreased to 0.55 after the photovoltaic system operates for 22 d. The photovoltaic system has a high availability of 0.998 which is constant at t = 20 d. The photovoltaic system will achieve maintainability of 1 at t = 13 d.
