3m-1 phases are displaced 120° in opposite and (3m+1) in the same direction as the fundamental. Here ‘m’ is even integer. So 5th harmonic is in negative sequence and 7th harmonic component in positive sequence.

Positive sequence components refer to the components of a three-phase electrical system that have the same magnitude and phase angle. These components are also known as the "direct sequence" or "positive sequence" components.
In a balanced three-phase system, the positive sequence components consist of three sinusoidal waveforms that have the same frequency and phase relationship. These components represent the fundamental frequency components of the system and are typically used for analysis and calculation purposes.
The positive sequence components are important in power system analysis and protection. They help in determining the steady-state behavior of the system, calculating power flows, and identifying faults in the system. By analyzing the positive sequence components, engineers can assess the performance and stability of the power system.
In addition, positive sequence components are used in the design and operation of power system protection devices, such as relays. These devices are designed to detect and isolate faults in the system, and they rely on the characteristics of the positive sequence components to make accurate decisions.
Overall, positive sequence components play a crucial role in understanding and analyzing three-phase electrical systems. They provide valuable information about the system's behavior and help ensure the reliability and stability of power systems.
