« Previous Question
The design Power Factor (PF) of a vessel's electrical system is generally 0.8 - 0.9. The system's greatest load is inductive. One notices a slow, gradual decrease, over time, in the PF, from normal/design. What can one do on board to maintain the normal, design PF and thus maintain electrical system's efficiency?
A) Determine that all induction motor driven pumps, fans, compressors, etc. are operating at their design capacity and design electrical load.
B) Add capacitive load to major inductive power load consumers.
C) Add resistive load to major inductive power load consumers.
D) Increase the entire electrical system's frequency.
