Electrical Power Analyzer enables multi-channel power grid parameter acquisition and the detection of harmonics and unbalance

Electrical Power Analyzer supports the simultaneous acquisition of four voltage and four current channels. It measures voltage and current amplitude, phase, frequency, and power factor; detects harmonics (from the 2nd to the 64th order), total harmonic distortion (THD), voltage flicker, and fluctuations; and captures three-phase unbalance as well as voltage swells and dips. Equipped with waveform recording and vector analysis functions, it is well-suited for verifying on-site electrical wiring and calculating retroactive billing adjustments.

Electrical Power Analyzer is a professional instrument designed to measure key power quality parameters, including voltage deviation, frequency fluctuation, harmonic distortion, three-phase unbalance, flicker, and voltage dips/swells. It features a 10-inch color touchscreen, large-capacity internal storage, and a built-in lithium battery, allowing for extended on-site data acquisition. The accompanying software generates test reports that comply with national standards, providing reliable data to support power operations and maintenance personnel in troubleshooting grid anomalies.

Electrical Power Analyzer utilizes an eight-channel synchronous sampling architecture, with four voltage channels and four current channels operating in parallel. Basic electrical parameters, harmonic indices, flicker/fluctuations, sequence components, and unbalance levels can all be captured in a single test. The harmonic measurement module compares results against national standard thresholds and provides alerts when limits are exceeded; users can also look up these national standard harmonic limits directly on the device. The instrument offers oscilloscope-style waveform viewing and vector (phasor) diagram displays, with zoom functionality for real-time waveform analysis. In three-phase, three-wire mode, it can automatically identify 48 different wiring configurations and calculate retroactive billing adjustments in the event of wiring errors. With optional clamp-on current transformers, it can also perform ratio and phase-angle error testing for low-voltage current transformers. The storage configuration allows for customizable recording intervals—ranging from one second to 1,000 minutes—enabling continuous recording for over 18 months when set to a one-minute interval. Test data can be saved to a USB flash drive for convenient offline access. The device is compact and lightweight, featuring a capacitive touchscreen interface similar to that of common smart devices, while also offering the option to use a mouse to accommodate individual user preferences. Equipped with a built-in lithium battery and an energy-saving mechanism, it can operate continuously for over ten hours without an external power source. The accompanying data analysis and management software allows for the retrieval of all field-collected records, tracks periodic load fluctuations, and generates standardized power quality test reports in compliance with national standards. This assists power utility personnel in identifying potential supply issues and developing appropriate mitigation strategies. The device is widely used in various field testing scenarios, including distribution network inspections, end-user electricity consumption audits, and grid-connection acceptance testing for new energy systems.
