Choose a suitable power systemAC Power Quality MonitorIt is a key step to ensure the stable operation of the power system and meet the standards of power quality. Select the appropriate one according to the needs of the power systemPower quality monitoringThe instrument is of great significance. Below, we will introduce how to choose a suitable power quality monitoring instrument from several aspects such as the requirements, functional characteristics, and technical indicators of power quality monitoring.

1. The demand for power quality monitoring

Before choosing a power quality monitoring instrument, it is first necessary to clarify the requirements for power quality monitoring. Different users may have different requirements for power quality, which generally include the following aspects:

1) Voltage stability. Voltage stability is a fundamental requirement for the operation of power systems. When selecting a power quality monitoring instrument, it is necessary to consider whether it can monitor voltage stability, and whether the accuracy and range of monitoring meet practical needs.

2) Voltage fluctuations and flickers. Voltage fluctuation and flicker are one of the important indicators of power quality, and for some factors affecting voltage fluctuation and flickerkeenFor equipment such as computers and precision instruments, it is necessary to choose a monitoring instrument that can accurately monitor voltage fluctuations and flicker.

3) Record of power quality events. For abnormal power quality events in the power system, such as voltage dips, voltage surges, and current surges, it is necessary to select a monitoring instrument with event recording function for later analysis and troubleshooting.

4) Harmonic monitoring. In the power system, harmonics are a common problem. For some devices that are sensitive to harmonics, it is necessary to choose a monitoring instrument that can accurately monitor the harmonic content and distortion rate.

5) Electricity metering. Electric energy metering is a necessary function for the operation of the power system, and it is necessary to select a monitoring instrument that can accurately measure power, energy, and power factor.

2. Functional Features

According to the needs of power quality monitoring, choose a power quality monitoring instrument with the following functional characteristics:

1) High precision.AC Power Quality MonitorThe accuracy of is very important for accurately monitoring power quality, and choosing a high-precision monitoring instrument can provide more accurate data.

2) Wide measurement range. The power quality monitoring instrument needs to have a wide measurement range to adapt to the working conditions of different power grids.

3) Real time monitoring and recording. The power quality monitoring instrument is required to have real-time monitoring and recording functions, which can promptly identify problems and record them for subsequent analysis and processing.

4) Data storage and transmission. Choose a power quality monitoring instrument with large capacity data storage and multiple data transmission methods to facilitate data storage and remote transmission.

5) Alarm and fault diagnosis functions. The power quality monitoring instrument needs to have an alarm function, issue an alarm in a timely manner, and provide fault diagnosis in order to handle abnormal power quality in a timely manner.
