Question 1 of 10
What is the primary function of load factor in power systems?
Load factor quantifies how efficiently energy is used by comparing the average load to the peak load.
Question 2 of 10
The load factor is calculated by dividing the average load by the:
The formula for load factor involves dividing the average load by the peak load during a specific period.
Question 3 of 10
What does a higher load factor typically indicate?
A higher load factor shows that the energy consumption is more consistent, leading to more efficient use.
Question 4 of 10
If a system uses 72,000 kWh over a month, with a peak demand of 200 kW, and the month has 30 days, what is the load factor?
Load Factor = (Total kWh) / (Peak kW * Days * 24hrs). Here, it is 72,000 / (200 * 30 * 24) = 0.5
Question 5 of 10
Load factor values are always:
By definition, the average load is never greater than the peak load, so the ratio is always less than 1.
Question 6 of 10
What time unit is NOT typically used to calculate load factor?
Load factor calculations are often done daily, weekly, monthly, or yearly to analyze trends, but an hourly basis is less common.
Question 7 of 10
What is the primary goal of improving the load factor?
A better load factor implies the efficient use of the generating equipment and consequently lowers costs.
Question 8 of 10
How can one improve the load factor of an electrical system?
Shifting the usage will reduce the peak demand, thus increasing the load factor.
Question 9 of 10
A low load factor signifies:
A low load factor implies that the difference between peak demand and average demand is significant, representing high peak demands.
Question 10 of 10
If the peak demand remains constant, what happens to the load factor if the average load increases?
As the average load approaches peak load, the ratio, the load factor, increases.
