CMM92001 Risk and Resilience of Electrical Devices

This assignment analyzes the risks associated with electrical devices, focusing on potential failures and mitigation strategies. It identifies risks such as partial operation halts, explosions, and property damage, referencing studies by Arghandeh et al. (2016), Hollnagel et al. (2016), Park et al. (2013), and Yodo and Wang (2016). The document explores the impact of these risks, including financial losses and potential loss of life. The solution proposes mitigation strategies, such as replacing old equipment and implementing high-quality components. The document includes figures illustrating electrical systems, faulty devices, and a partially working transformer, along with the mitigation strategies. This assignment aims to consolidate understanding of risk and resilience in electrical engineering. The assignment is based on the brief for CMM92001-2019-2: Risk and Resilience Engineering Assessment 4, requiring a digital information poster and a 5-minute video or audio recording to present the findings.

Risk and Resilience Engineering
Partial Activity of Electrical Devices Halting Normal Operations
Advantages of Electrical Devices
• High Efficiency
• Reducing human effort
• Instant responses (Park et al.
2013)
• Accurate Execution
Risks related to the Electrical Devices:
• Partial working halts normal operation
• May lead to further problems like failure
of system (Arghandeh et al. 2016)
• Might cause explosions and loss of
property if risk is not mitigated
Impact of Electrical Device
Failure:
• Disaster in terms of charring of
properties (Yodo and Wang
2016).
• Possible explosions leading to
monetary losses and loss of
human lives
The mitigation strategies:
• The old machine parts have to be
replaced
• High-quality types of equipment
needs to be implemented (Hollnagel,
Woods and Leveson 2016)
• Defective components have to be
isolated and replaced
