5 Questions
Question 1 of 5
In a Star (Y) connection, how is the phase voltage related to the line voltage?
The phase voltage in a Star connection is the line voltage divided by the square root of 3.
Question 2 of 5
Which connection type is typically used for starting motors with reduced voltage and current?
Star connection is used for starting motors due to the reduced voltage and current during startup.
Question 3 of 5
In a Delta (Δ) connection, what is the relationship between phase voltage and line voltage?
In a Delta connection, the phase voltage is equal to the line voltage.
Question 4 of 5
Which connection type is best suited for long-distance power transmission?
Star connections are preferred for long-distance transmission due to the lower current, which reduces losses.
Question 5 of 5
Which connection is commonly used for running motors at full load with high torque?
Delta connections are used for running motors at full load due to the higher power and torque capabilities.
