WEG WEGMETER Power Quality Analyser

The WEG WEGMETER Power Quality Analyser is a panel-mount or portable power quality measurement and analysis instrument providing comprehensive measurement of power quality parameters including voltage and current harmonics up to the 63rd order, total harmonic distortion (THD-V, THD-I), interharmonics, flicker (Pst, Plt), unbalance, sags, swells, and transients in compliance with IEC 61000-4-30 Class A — the most stringent power quality measurement standard. The WEGMETER measures all standard electrical parameters (V, I, P, Q, S, PF, frequency, kWh, kVArh) with Class 0.2 accuracy, going well beyond the capability of standard energy meters. It communicates via Ethernet (TCP/IP), Modbus TCP, RS-485 Modbus RTU, and optional DNP3, making it suitable for integration into both industrial SCADA and utility-grade supervisory systems. For Saudi Arabia's industrial, commercial, and utility customers managing power quality compliance, energy costs, and harmonic-driven equipment problems, the WEGMETER is a professional-grade instrument that combines the functionality of a revenue-grade meter with a full power quality recorder in a single DIN-rail package.

The WEGMETER is type-tested to IEC 61000-4-30 Class A, the international standard for power quality measurement methods and accuracy used for contractual, regulatory, and verification measurements. Its 256-sample-per-cycle waveform acquisition captures voltage and current waveforms at high resolution, enabling accurate harmonic analysis to the 63rd order — sufficient to identify harmonic problems caused by the variable speed drives, UPS systems, LED lighting, and non-linear industrial loads that are prevalent in Saudi Arabia's modern industrial and commercial facilities. Event recording with pre-trigger and post-trigger waveform capture stores voltage sags, swells, and transients with timestamps, providing the audit trail required for power quality compliance reporting to SEC or for investigating harmonic disturbance complaints from neighbours in shared SEC transformer installations.

Power quality management is increasingly important in Saudi Arabia's industrial and commercial sectors for three converging reasons: SEC's harmonics and power quality technical specification (GS-EE-PQU) requires large consumers to maintain THD voltage within IEC 61000-3-6 limits at the point of common coupling; the proliferation of VFD-driven equipment, LED lighting, and UPS systems in new Saudi facilities generates significant harmonic content that can overheat transformers and cause protection relay maloperation; and Vision 2030 smart grid ambitions require accurate power quality data from major consumers for network planning. ARAMCO, SABIC, and large commercial developers increasingly install power quality analysers at incoming supply points as a condition of ARAMCO and SABIC network connection approval.

Razz Middle East supplies the WEG WEGMETER with full commissioning support including CT/VT connection verification, Modbus TCP integration with client SCADA or BMS, and power quality baseline measurement report. We provide power quality audit services using the WEGMETER as the measurement instrument, identifying harmonic problems and recommending mitigation measures (passive filters, active filters, detuned reactor/capacitor banks). All pricing is in SAR. Contact Razz Middle East for WEGMETER demonstrations, rental for temporary power quality surveys, and permanent installation supply.
