Power Quality Meter
At Big Belly Sales Corporation, we offer a state-of-the-art Power Quality Meter designed for high-precision measurement, real-time monitoring, and control of electrical parameters. Built to support both single-phase (1Ø-2W) and three-phase (3Ø-3W / 3Ø-4W) systems, our meter comes in options with LED or LCD displays. It accurately tracks voltage, current, frequency, power factor, active/reactive power, total harmonic distortion (THD), maximum demand (MD), imported/exported energy, and phase angles. With built-in pulse output and RS-485 Modbus communication, it integrates seamlessly into EMS (Energy Management Systems), SCADA platforms, dashboards, and mobile applications for continuous, real-time monitoring.
Applications
Our Power Quality Meter is ideal for a wide range of industrial and commercial environments. Whether you operate a manufacturing plant, process unit, commercial building, data centre, or utility system, this meter delivers critical insights. It is particularly useful for energy audits, ISO 50001 compliance, demand-management projects, green-building certification, and continuous monitoring of motors, HVAC systems, lighting circuits, and power distribution panels.
Construction & Design
Designed for industrial rigor, our meter is available in compact and panel-mount variants, enclosed in a rugged housing that withstands harsh environments. The internal architecture uses input from CTs (Current Transformers) and VTs (Voltage Transformers), backed by advanced signal-processing and microcontroller control to ensure high reliability. Key technical features include harmonic analysis (up to 32 orders), min/max value capture, load forecasting, RS-485 Modbus interface, and optional relay outputs. A user-friendly interface ensures ease-of-use, while the durable enclosure safeguards long-life performance.
