Surge protector systems are designed to protect electrical equipment against high voltage transients - surges. During operations, they develop faults and may fail to provide the required protection without users being aware. Hence, the necessity for a more reliable and effective way of monitoring such systems using the Internet of Things (IoT) technology. This paper presents a an IoT based implemented model which adequate monitor the system status in a distributed approach, and also predict the probability of subsequent failure. The surge protector monitoring system was built using a Zmpt101b
For customers to receive dependable service, damaged lines need to be repaired as quickly as possible and put back in use. All types of faults must be avoided to ensure or reduce how much energy can be distributed with ease. Estimates for both sustained and transitory faults are provided by fault locators. The little damage brought on by transient defects is difficult to see during an inspection. Locators for faults aid in pinpointing the places for quick repairs to stop recurrence and the ensuing significant harm. This paper discusses a few distribution system fault location strategies used i
In this study, sodium silicate was successfully synthesized from silica rich sand located at the western desert of Iraq. After the pretreatment silica sand, it was characterized using X-Ray Fluorescence (XRF). The results indicate that the sand had 84% silica from total metal oxides percent of 87.7%. Sodium silicate was prepared from the silica sand using dry fusion method. The effect of (NaOH/sand) ratio of (1:1, 1.2:1, and 1.4:1) at different fusion temperatures of (400,500, and 600)0C was studied. For comparison commercial sodium silicate obtained from Aldrich was used. All prepared samples
Major challenges encountered when drilling in the last hole in Noor field due Shale problems (sweeling, sloughing, washout, …) which are often caused by Incompatibilities of drilling fluids and shale, In Tanuma formations most of the drilling problems occur in the last hole because of the high concentration of shale about 85% (Ahmed K. Abbas,2018), This shows that selecting appropriate drilling mud is important when drilling through a shale formation. Compared with Non-inhibitive fluids, the inhibitive fluids have advantages such as resistance to Swelling, resistance to Collapse, being good
