Structural Appearance of Power Quality Monitoring Meters
AC Power Quality Monitor: Dimensions and Terminal Layout
- The top of the instrument’s front panel features an LCD display, with the keypad below it. The top edge houses the wiring connections, and the right side contains other ports (Ethernet, charging, USB, and SD card).
The terminal block area at the top of the 3 phase power quality meter is shown in the figure.
- Includes: voltage input terminals UA, UB, UC, and UN; clamp-on current transformer interfaces (Phase A clamp, Phase B clamp, and Phase C clamp).
Right-side view of the power quality analytics instrument
- Ethernet port (used for firmware updates); not for user use.
- Charger port: Used to connect the charger. When the instrument’s battery is low, connect the charger to this port to recharge the instrument.
- USB port: Supports USB flash drives. Connecting a USB flash drive allows you to link the instrument to a computer, making it easy to copy data directly to the backend management computer. See the side view in the figure on the right.
- SD card slot: Supports external SD cards for storing large amounts of data, enabling long-term experimental monitoring.
