Power Quality Online Monitoring System - Real-Time Electrical Parameter Analysis, Harmonic Detection & Remote Monitoring

With the vigorous development of my country's national economy, the power load has increased dramatically, especially the continuous growth of impact and nonlinear load capacity of power electronic switching equipment, electrified railways, arc furnaces, etc., which has caused the power quality of the power system to deteriorate. The power quality problems such as waveform distortion, voltage fluctuation and flicker, and three-phase imbalance in the power grid are becoming more and more serious. As a result, transformer overheating, increased network loss, metering instrument errors, and communication interference will not only reduce the safety of the power supply and use equipment itself, but also seriously threaten the safety and economic operation of the power system. In order to protect the safe operation of the power system, all countries currently attach great importance to the management of power quality and have formulated relevant standards. my country has also successively promulgated national standards involving seven aspects of power quality, and relevant departments have also formulated corresponding "Power Quality Management Measures" - Appendix.

After a thorough investigation of power quality measurement and control, a careful analysis of the current status of similar products at home and abroad, and tracking the advanced level of international peers, our company has successfully developed a new generation of SC-GP-PQM power quality online monitoring device.

This device is a high-performance multifunctional power quality test and analysis instrument. It adopts DSP+ARM+CPLD core, 4.3-inch large-screen color LCD display, more compact structure and more powerful functions. It is suitable for 220KV, 110KV and 35KV substations, power plants and large electricity users.
