GE PQMII-T20

The GE PQMII-T20 is a power quality meter and energy monitoring device produced by General Electric (GE). This device is designed to monitor and analyze the quality of electrical power in industrial and commercial settings. Here is a brief description of some of its key features and capabilities:

1. Power Quality Monitoring: The PQMII-T20 is primarily used for power quality analysis. It can continuously monitor various power parameters such as voltage, current, frequency, and harmonics. This allows users to identify and diagnose issues related to power quality, such as voltage sags, swells, harmonics distortion, and flicker.
2. Energy Management: In addition to power quality monitoring, the PQMII-T20 can measure and record energy consumption data. This is crucial for energy management and cost optimization in industrial and commercial facilities.
3. Data Logging: The device can log data over extended periods, providing historical records of power quality and energy consumption. This data is often used for compliance reporting, troubleshooting, and trend analysis.
4. Communication: The PQMII-T20 typically supports various communication protocols like Modbus, Ethernet, and serial communication, which enable remote monitoring and integration with other control and management systems.
5. User Interface: It comes with a user-friendly interface, often featuring a touchscreen or a digital display, allowing users to configure settings, view real-time data, and generate reports directly from the device.
6. Alarms and Notifications: The PQMII-T20 can be configured to generate alarms and notifications when power quality parameters exceed predefined thresholds. This feature helps in quickly identifying and addressing issues to prevent equipment damage or downtime.
7. Harmonics Analysis: This device can analyze harmonics up to a certain order, helping users understand the impact of non-linear loads on their electrical systems.
8. Event Logging: It can record and timestamp events such as disturbances, voltage interruptions, and other significant power quality events, aiding in root cause analysis.
9. Accuracy and Precision: GE’s power quality meters are known for their accuracy and precision, ensuring reliable measurement and analysis of electrical parameters.
10. Industrial Durability: The PQMII-T20 is typically designed to withstand the rigors of industrial environments, including resistance to dust, moisture, and temperature variations.
