Want to know Power Quality Metering clearly? This article will introduce the power quality metering and monitoring solutions from power quality definition, reasons of monitoring power quality, factors of power quality and power quality monitoring equipment and devices.
Power quality metering and monitoring analyzes the overall power quality by measuring parameters such as unbalance, voltage deviation, voltage magnitude, harmonics, sag and swell monitoring, frequency change and power factor. Finally, it helps users proactively deal with power quality issues. For example, through the monitoring and analysis of total harmonics and subharmonics, when the harmonic data is not abnormal, users can proactively prevent damage and system interruption by using external compensation equipment.
The assessment of power quality is usually based on the analysis of several key power parameters, including:
Voltage sags and swells refer to the decrease and increase of voltage quickly, which is the primary power quality problem. Voltage sags and swells can cause users to stop production, lose computer data, increase the defective rate of output, and malfunction power system electrical appliances. Lightning strikes, overhead transmission line failures, and full-voltage starting of large asynchronous motors can all cause voltage sags or interruptions to varying degrees. Using the Blue Jay multifunction meter’s individual waveform capture, users can capture multiple waveform cycles through different channels and record multiple groups in the meter’s dedicated internal memory.
Three-phase voltage imbalance problems usually refer to voltage imbalance at the common connection point caused by negative sequence components. Using the Blue Jay multi-function meter to analyze the phase loss caused by the circuit through the degree of imbalance allows users to better prevent the dangers of three-phase imbalance problems to the safety of the power grid.
The main cause of frequency deviation is the imbalance of the active output and active load of the generator. Frequency changes have a great impact on the normal operation of motors in the power system, which can be effectively monitored with the Blue Jay multi-function meter.
Individual waveform captures can track slowly changing changes in the electrical waveform. Blue Jay multi-function meters can graphically display and record individual waveform captures.
Harmonics, which means waveform distortion, are the most common problem in power quality. Harmonic Distortion analyzes non-linear loads connected to the distribution system that affect the frequency and cause problems such as misfires, overheating, and voltage spikes. Blue Jay multifunctional meters can read individual harmonic measurements from 2-63 and THD (Total Harmonic Distortion).
Power factor is the ratio of actual power flowing to the available load, accurately describing the feasibility of the power supply. All Blue Jay multi-function power meters help users track this ratio and record it in the unit’s internal memory.
The Blue Jay multifunction power quality monitoring device is a powerful, easy-to-operate power quality solution to meet your power quality analysis needs. The multifunction Power quality monitor can effectively and comprehensively do power quality monitoring. It is suitable for a variety of low-voltage 3P3W or 3P4W installations, helping you easily monitor grid quality, identify potential problems, and ensure power security.
