Transformation equipment conditional monitoring technology is the key technology of intelligent substation construction, and it is also one of the core content of intelligent substation construction. Guangxi power grid has constructed a sensor network based variable and integrated electrical equipment on-line monitoring and evaluation platform. In the platform, through the equipment fault diagn...
The Circuit Breaker (CB) is one of the most important equipment in power systems. CB must operate reliably to protect power systems as well as to perform tasks such as load disconnection, normal interruption, and fault current interruption. Therefore, the reliable operation of CB can affect the security and stability of power network. In this paper, effects of Condition Monitoring (CM) of CB on...
Industrial equipment is usually repairable. Reliability of repairable systems depends on maintenance actions, and is characterized by mean cumulative function or failure intensity function of failure processes. Evolution trend of the failure intensity function is called the system-level failure pattern in the literature. The failure pattern plays an important role in preventive maintenance deci...
Due to their special environments, rural areas are susceptible to rodent outbreaks. Extensive damage to agricultural produce, equipment and buildings on the one hand and outbreaks of zoonotic diseases on the other are among the health and economic impacts of a rodent outbreak. Failure in controlling such events may even result in social issues, such as, village abandonment and mass migration to...
Background: FMEA is one of the best known system safety techniques widely used as an identification tool. The purpose of this study was to apply FMEA method to identify and assess the risks posed by power lines in a residential area is Hasyrabad, Ahwaz. Materials and Methods: First, we identified the power line process and the equipment involved. Later, we determined the failure modes of equipm...
Nasal high flow (NHFTM) oxygen using the OptiflowTM system (Fisher & Paykel Healthcare Limited, Panmure, Auckland, New Zealand) is frequently used in our hospital in the management of type one respiratory failure. We present two cases where we have used NHFTM in our maternity unit. In the first case, this was used in the management of respiratory failure and as an adjunct at induction of genera...
A variety of reasons, specifically contact issues, irregular loads, cracks in insulation, defective relays, terminal junctions and other similar issues, increase the internal temperature of electrical instruments. This results in unexpected disturbances and potential damage to power equipment. Therefore, the initial prevention measures of thermal anomalies in electrical tools are essential to p...
Digital signal processing (DSP) underpins modern wireless and wireline communications, medical diagnostic equipment, military systems, audio and video equipment, and countless other products, becoming increasingly common in consumers' lives. Due to advances in semiconductor technology, ever more complex DSP algorithms, protocols, and applications are now feasible, which, in turn, increase the c...
