Lower Order Harmonics vs Higher Order Harmonics
Lower order harmonics and higher order harmonics are two different types of harmonics present in an electrical system. Understanding the difference between these two types is crucial in order to effectively reduce their effects.
Assertion (A): The lower order harmonics are reduced by using some technique while the higher order harmonics are reduced by using a filter.
The assertion states that lower order harmonics are reduced using some technique, while higher order harmonics are reduced using a filter. Let's examine this statement in detail.
Reason (R): The cost of the filter is reduced and at the same time transient response is also improved to a great extent.
The reason provided states that the use of a filter reduces the cost and improves the transient response. Let's analyze this reason further.
Explanation:
Lower Order Harmonics
Lower order harmonics refer to the harmonics with lower frequencies, typically the fundamental frequency and its multiples. These harmonics can be reduced using various techniques such as:
1. Passive Filtering: Passive filters, such as inductors and capacitors, can be used to attenuate lower order harmonics. These filters are designed to introduce impedance at specific frequencies, thereby reducing the harmonics.
2. Active Filtering: Active filters use active components such as transistors and operational amplifiers to actively cancel out the lower order harmonics. These filters are more effective in reducing harmonic distortion.
3. Phase Shifting: By introducing a phase shift in the system, lower order harmonics can be canceled out or minimized. This technique is commonly used in power factor correction circuits.
Higher Order Harmonics
Higher order harmonics refer to harmonics with frequencies higher than the fundamental frequency. These harmonics are usually reduced using filters, specifically harmonic filters. Harmonic filters are designed to attenuate specific harmonic frequencies, effectively reducing the higher order harmonics.
Explanation of Assertion and Reason:
The assertion states that lower order harmonics are reduced using some technique, while higher order harmonics are reduced using a filter. The reason provided states that using a filter reduces cost and improves transient response.
The assertion is true because both lower order and higher order harmonics can be reduced using different techniques. Lower order harmonics can be reduced using techniques such as passive filtering, active filtering, and phase shifting. On the other hand, higher order harmonics are typically reduced using harmonic filters.
The reason is the correct explanation of the assertion. Using a filter to reduce higher order harmonics can be a cost-effective solution compared to other techniques. Additionally, by effectively reducing higher order harmonics, the transient response of the system can be improved.
Therefore, the correct answer is option 'A': Both A and R are true, and R is the correct explanation of A.
