Harmonic analysis is a technical method used to detect and analyze harmonic problems in power systems. For power engineers and technicians, it is important to choose power instruments suitable for harmonic analysis. This article will provide a detailed introduction on how to select power instruments suitable for harmonic analysis.

Firstly, when selecting an instrument, the following aspects need to be considered: harmonic measurement range, measurement accuracy, data storage and communication functions, operational convenience and reliability, etc.

1、 Harmonic measurement range

The range of harmonic measurement is one of the key factors in selecting a harmonic analyzer. There are varying degrees of harmonic pollution in different power systems, so it is important to choose an appropriate range for harmonic measurement based on actual needs. If you need to measure low-frequency harmonics (such as 2nd and 3rd harmonics), you need to choose an instrument that can measure low-frequency harmonics.

2、 Measurement accuracy

Measurement accuracy is an evaluationHarmonic analyzerOne of the important indicators of performance. High precision instruments can provide accurate data and better meet user needs. Therefore, when selecting a harmonic analyzer, it is necessary to consider its measurement accuracy and choose an instrument with higher measurement accuracy.

3、 Data storage and communication functions

Data storage and communication functions are one of the important features of harmonic analyzers. Choosing an instrument with data storage function can facilitate users to view data, analyze data, and diagnose faults at any time. At the same time, the instrument should also have communication function, which can transmit data to other devices or exchange data with other devices.

4、 Convenience of operation

Convenience of operation is one of the important factors to consider when purchasing a harmonic analyzer. Choosing instruments that are easy to operate and fully functional can enhance users' work efficiency and improve their work experience.

5、 Reliability

Reliability is crucial when purchasing a harmonic analyzer很An important aspect. Choosing instruments with stability and durability can better meet user requirements and provide long-term reliable services.
