How can you explain voltage sag risks to non-technical stakeholders?

1 Define voltage sag

The first step is to define what voltage sag is and how it differs from other power quality issues, such as voltage swell, interruption, or flicker. You can use a simple analogy, such as comparing voltage sag to a water pressure drop in a faucet. You can also use a graphical representation, such as a voltage-time curve, to show the magnitude and duration of voltage sag. You should explain the typical range and frequency of voltage sag events, and how they are measured and classified by standards, such as IEEE 1159 or IEC 61000.

2 Identify the sources

The next step is to identify the possible sources of voltage sag, both internal and external to the electrical system. You should explain how different types of faults, such as short-circuit, ground, or arc faults, can cause voltage sag on the affected or adjacent circuits. You should also explain how external factors, such as weather conditions, utility operations, or neighboring loads, can affect the voltage quality of the supply. You should provide examples of common scenarios or events that can trigger voltage sag, such as storms, motor starting, or transformer switching.

3 Assess the impacts

The third step is to assess the potential impacts of voltage sag on the electrical equipment and systems. You should explain how voltage sag can affect the functionality, performance, or lifespan of different types of equipment, such as computers, controllers, drives, or sensors. You should also explain how voltage sag can affect the operational efficiency, quality, or safety of different processes or applications, such as data processing, manufacturing, or healthcare. You should provide examples of typical consequences or costs of voltage sag, such as equipment failure, data corruption, product defect, or injury.

4 Recommend the solutions

The final step is to recommend the possible solutions to mitigate or prevent the risks of voltage sag. You should explain the benefits and limitations of different types of solutions, such as power conditioning devices, backup power sources, voltage regulation systems, or fault detection and isolation systems. You should also explain the factors that influence the selection and implementation of the solutions, such as technical feasibility, economic viability, regulatory compliance, or customer satisfaction. You should provide examples of successful cases or best practices of voltage sag mitigation or prevention in similar or relevant contexts.

By following these steps, you can explain voltage sag risks to non-technical stakeholders in a clear and concise way. You can also use visual aids, such as diagrams, charts, or videos, to enhance your explanation and engagement. Remember to tailor your explanation to the needs and expectations of your audience, and to use simple and familiar language, avoiding jargon or acronyms. By doing so, you can increase the awareness and understanding of voltage sag risks, and foster the collaboration and support for the solutions.
