Simulation of faults causing analog behavior in digital circuits
… is to develop effective simulation methods for electrically oriented faults in digital metal-oxide semiconductor (MOS) very large scale integrated (VLSI) circuits. In particular, we are interested in the simulation of permanent electrical faults that are difficult to model using a logic-level or …

Dissolved Gas Analysis of Insulating Transformer Oil Using Optical Fiber
… transformers are designed to handle immense electrical loads in hostile environments. Long term placement is desired, however by being under constant heavy load transformers face mechanical, thermal, and electrical stresses which lead to failures of the protection systems in place. The …

Assessment of fire and explosion hazards in large-scale battery energy storage systems intended for Namibian green hydrogen projects
… batteries, leading to thermal runaway, like electrical faults, and mechanical damage. It also examines various battery chemistries and their respective safety profiles, alongside an analysis of global case studies to draw lessons for Namibia. Fault Tree Analysis (FTA) and statistical tests …

Study on 6, 12 and 24 pulses D-STATCOM for voltage SAG mitigation
… This issue always brought up for discussion by Electrical power committee all around the world. There are many causes of voltage sag such as overload by consumption area, electrical faults on utility lines, switching operations, trip or short circuit and any single or three phase faults. In …

The characterisation and automatic classification of transmission line faults
… dependent on a reliable electricity supply. Electrical faults on transmission lines are a cause of both interruptions to supply and voltage dips. These are the most common events impacting electricity users and also have the largest financial impact on them. This research focuses on …

Intelligent voltage dip mitigation in power networks with distributed generation
… power quality (PQ) cannot be over-emphasized in electrical power system operation and management. PQ problem is associated with any electrical distribution and utilization system that experiences any voltage, current or frequency deviation from normal operation. In the current power and energy …

Fiber-Wireless Sensor Networks for Monitoring Distributed Generation in a Smart Grid Environment
… for certain delay-critical SMR events (like electrical faults). Therefore, appropriate Quality of Service (QoS) mechanisms are needed to satisfy the delay requirements of these SMR events. In this thesis, a number of location-dependent communication topologies to monitor and control SMR units …

Toward high-level synthesis of reliable circuits through low-cost modulo shadow datapaths
… = 3, we observe coverages of 99.2% for stuck-at faults, 99.5% for soft errors, and 99.8% for timing errors with a 25.7% area cost and negligible performance impact. When b = 5, we observe coverages of 99.4% for stuck-at faults, 99.8% for soft errors, and 99.9% for timing errors with a 48.5% area …
