FAQs on Demand Factor, Power Systems, Electrical Engineering, GATE Video Lecture - Electrical Engineering (EE)

1. What is the demand factor in power systems?
Ans. The demand factor in power systems is a measure of the ratio between the maximum demand and the connected load. It represents the extent to which the maximum demand is higher than the average load. The demand factor is typically calculated by dividing the maximum demand by the connected load.
2. How is the demand factor calculated in electrical engineering?
Ans. The demand factor in electrical engineering can be calculated by dividing the maximum demand by the connected load. For example, if the maximum demand is 100 kW and the connected load is 200 kW, the demand factor would be 0.5 or 50%. This means that the maximum demand is only 50% of the connected load.
3. Why is the demand factor important in power systems?
Ans. The demand factor is important in power systems because it helps in determining the capacity requirements of electrical equipment, such as transformers and generators. By understanding the demand factor, engineers can accurately size and design equipment to meet the maximum demand without oversizing and wasting resources. It also plays a crucial role in load forecasting and planning for future growth.
4. How does the demand factor affect power system reliability?
Ans. The demand factor directly impacts power system reliability. A low demand factor indicates that the load is evenly distributed and the system is operating efficiently. However, a high demand factor can lead to overloading and potential system failures. By understanding and managing the demand factor, power system operators can ensure reliable and stable operation of the system.
5. How can the demand factor be improved in power systems?
Ans. The demand factor can be improved in power systems through various measures. One approach is to promote energy-efficient practices and technologies to reduce overall energy consumption. This can help decrease the gap between the maximum demand and connected load. Additionally, implementing demand response programs can encourage consumers to reduce their electricity usage during peak demand periods, thereby improving the demand factor and system efficiency.
