Aviation Mechanic General "Basic Electricity" Questions and Answers Already Passed Why is alternating current (AC) more commonly used for power distribution than direct current (DC)? AC can be easily transformed to higher or lower voltages, making it more efficient for long- distance transmission. What effect does temperature have on the resistance of a conductor? As temperature increases, the resistance of a conductor typically increases. What does it mean when a circui...

Two phase conductors of a 138kV transmission line come in contact due to a storm, creating a phase to phase fault. The distance relay at each end of the line tripped and isolated the line. What two measured parameters of the line caused the distance relay to operate? Temperature and length MWs and MVARs Voltage and current Resistance and Impedance CORRECT ANSWER Voltage and current What is the main cause for having low voltage on the Transmission and Distribution system? Over gener...
