ER-VMA Harmonic Monitoring Series Device

◆ Product Overview

The ER-VMA harmonic monitoring series device can automatically collect, monitor, analyze, and store power grid data. It can also upload data to the monitoring system using multiple standard protocols according to user requirements to meet their requirements for power quality. The main functions of the device are shown in the table below:

1. Basic electrical parameter measurement	5. (Voltage, current) 2-50th harmonic total distortion rate
2. Three phase voltage imbalance	6. Alarm for exceeding the limit of electrical parameters
3. Three phase voltage deviation	7. Display real-time waveform
4. (Voltage, current) 2-50th harmonic content	8. Remote transmission of data

The ER-VMA harmonic monitoring device has powerful functions and simple operation, and is a new generation of digital, automated, and intelligent products. It has the characteristics of deep harmonic monitoring, complete electrical parameter anomaly alarm, and strong traceability of complete historical event records.
