The negative sequence has the phase sequence just __________ to positive sequence, hence __________________ produced in opposite direction.
opposite, Voltage
same, Torque
opposite, Voltage & Current
opposite, Voltage, Current & Torque
opposite, Voltage, Current & Torque
Quick Trick: Remember that the negative sequence is the reverse of the positive sequence, affecting voltage, current, and torque due to its direction.
Remember that the negative sequence is the reverse of the positive sequence, affecting voltage, current, and torque due to its direction.
Identify the Phase Sequence
In electrical machines, the phase sequence defines the order of the phases · The negative sequence is the reverse of the positive sequence.
Understand the Effects of Sequences
The negative sequence results in voltages and currents reversing direction, which affects torque in induction motors.
Determine the Correct Terms
Since negative sequences cause opposing effects, it’s important to recognize that both voltage and current are affected, leading to opposite torque as well.
A: Voltage only is incomplete; B: Same sequence is incorrect; C: Voltage & Current are correct, but misses Torque.
D is correct because the negative sequence causes voltage, current, and torque to act in the opposite direction to that of the positive sequence.
In questions about phase sequences, pay attention to the definitions and common consequences of negative versus positive sequences.
