SYEZ11 Multifunctional Harmonic Monitor

SYEZ11 multifunctional harmonic monitor can continuously and effectively collect, store and count voltage, the effective value of voltage fundamental wave and the content of 2-31 harmonics. It is used for electric power, automobile, metallurgy, machinery manufacturing, chemical industry, papermaking, textile, coal , Shipbuilding, communications, airports, large venues, high-rise buildings and other important places to control harmonic pollution to provide reliable monitoring data.

The high-end harmonic monitor with 32-bit ARM as the core is suitable for power users' collection, storage, statistics, display, transmission, analysis and other fields of grid harmonic data. It is an independent harmonic monitoring designed for networked management. Device. The modular design of the communication terminal, combined with the voltage quality information management system that complies with the "Shunyang Power Quality Monitor Communication Protocol", realizes the command interaction between the CAC and the device and the active reporting of device data, which is an ideal harmonic monitoring Instrument upgrade products.
