Supply AT358 power quality monitoring instrument

Product Overview: power quality monitor is running the grid quality monitoring and analysis of the specific products that can provide electricity to run the power quality data voltage / current / frequency, phase unbalance, power / power monitoring and harmonic analysis. analysis, and equipped with large-capacity memory, the power grid can be a long period of data acquisition and monitoring, Internet / Intranet network-based remote monitoring software, you can upload the collected data B / S structure to the monitoring center, technical staff through networked computers, each monitoring point can be achieved centralized monitoring and power quality analysis and management. Design Features: ◆ have GPRS wireless transmission capabilities and an Ethernet remote transmission capabilities, real-time data can be learned at any monitoring points each, and through remote control technology, so that at any time for any one monitoring point to modify settings and doing special detection . ◆ AT358 can view the recorded data anywhere, at any time, and detailed in-depth analysis on a PC. ◆ If abnormal power event occurs, AT358 with the fastest speed alarm, and by the raw data can be quickly dealt with the problem of equipment and device location on the computer. ◆ company constantly improve monitoring terminal program, customers can remotely download and install, easy to update monitoring terminal program. ◆ built-in high-capacity Flash memory disks, you can ensure the integrity of the length of recording time and recording data. Product Features: ◆ power quality parameter monitoring functions: 1. to measure the three-phase three-wire, three-phase four-wire (three voltage and four current) voltage, current, frequency, and record the change in trend. 2. The measure phase four-wire power system phase active power, apparent power, reactive power, power factor, and record changes in the trend of three-phase active. Voltage and current imbalance 3. measure three-phase power system and record its trends. The measure three-phase voltage, and 2 to 25 times the fundamental harmonic current, and total harmonic distortion. And record where it's trends. 5. measure the voltage swell / sag and voltage fluctuations and flicker. 6. Capture grid transient (358A) ◆ System management functions: ● Data management Basic measurements: See the basic measurement functions stored in the resulting data.
