The Electrical Power Analyzer's four-channel synchronous measurement capability enhances the efficiency of photovoltaic grid-connected testing

Specifically developed for photovoltaic grid-connected power distribution, industrial and mining power distribution, and low-voltage power grids, the Electrical Power Analyzer features simultaneous measurement of four voltage and four current channels, capable of detecting key indicators such as harmonics from the 2nd to the 64th order, flicker, and three-phase imbalance.

The Electrical Power Analyzer is a high-precision testing instrument specifically designed for detecting power quality issues in the power grid, such as waveform distortion, harmonic content, and three-phase imbalance. This device also features electrical parameter testing and vector analysis capabilities, accurately measuring various electrical parameters including voltage, current, active power, reactive power, phase angle, power factor, and frequency. In photovoltaic power plant grid-connected testing scenarios, this device can monitor voltage harmonics, flicker, and other parameters at the inverter output in real time, ensuring that grid-connected power meets national standards.

This tester features a flat panel design, making it lightweight and portable, typically weighing less than 2 kilograms. The device can be carried by staff with one hand to various scenarios such as substations, factory workshops, and new energy power plants, eliminating the need for fixed testing stations and greatly improving the flexibility of on-site operations. It features a large-size color LCD touchscreen, with operation similar to tablets and smartphones, making it simple and easy to learn.

In terms of measurement capabilities, the Electrical Power Analyzer employs multi-channel synchronous sampling technology. Four voltage channels and four current channels can be measured simultaneously, covering a voltage measurement range of 0 to 900V and a frequency measurement range of 42.5Hz to 69Hz, enabling measurements of 50Hz and 60Hz power systems. Voltage RMS accuracy is ≤0.1%, current RMS deviation is ≤0.3%, and phase angle error is ≤0.1°.

The Electrical Power Analyzer can measure voltage and current harmonics from the 2nd to the 64th order, as well as total harmonic distortion (THD). For flicker measurement, it supports short-time flicker (PST) and long-time flicker (PLT) measurements. The three-phase unbalance analysis function covers positive-sequence, negative-sequence, and zero-sequence voltage and current measurements. The device features a built-in high-performance lithium-ion battery, enabling it to operate continuously for 8 to 10 hours or more without an external power source. Its operating temperature range is -20℃ to 50℃, making it adaptable to various field environments. The device measures 280mm × 210mm × 58mm and weighs approximately 2kg, making it easy to carry and deploy on-site.
