Which of the following is correct?a)Load factor = capacitor x utilisa...
Explanation:
Load factor, Capacitor factor, and Utilisation factor are three different terms used in electrical engineering. Let's understand each term and its relation to the other.
Load Factor:
Load factor is defined as the ratio of average load to the maximum demand during a specific period. It is represented as a percentage. Load factor is used to measure the efficiency of a power system. A high load factor indicates that the power system is running efficiently.
Capacitor Factor:
Capacitor factor is defined as the ratio of the reactive power supplied by the capacitor to the total reactive power consumed by the load. It is represented as a decimal or a percentage. Capacitor factor is used to measure the effectiveness of a capacitor in reducing the reactive power demand of a power system.
Utilisation Factor:
Utilisation factor is defined as the ratio of the actual energy consumed by the load to the energy that would have been consumed if the load had operated continuously at its maximum demand. It is represented as a percentage. Utilisation factor is used to measure the efficiency of energy utilization.
Relation between Load Factor, Capacitor Factor, and Utilisation Factor:
The correct formula relating the three terms is:
Capacitor factor = Load factor x Utilisation factor
This formula shows that the capacitor factor is directly proportional to the product of the load factor and the utilisation factor. In other words, the effectiveness of a capacitor in reducing the reactive power demand of a power system depends on the load factor and the utilisation factor.
Conclusion:
Load factor, Capacitor factor, and Utilisation factor are important terms used in electrical engineering to measure the efficiency and effectiveness of a power system. The correct formula relating these terms is Capacitor factor = Load factor x Utilisation factor.
