Product Description
The LD-608 Portable Power Quality Analyzer, also known as a handheld power quality analyzer, portable power quality analyzer, and three-phase power quality analyzer, is used for testing electrical parameters and vector analysis. The three-phase power quality analyzer is a device for detecting power quality issues in the power grid, such as waveform distortion, harmonic content, voltage fluctuations and flicker, and unbalanced three-phase power. This handheld power quality analyzer can accurately measure various electrical parameters, including voltage, current, active power, reactive power, phase angle, power factor, and frequency. The LD-608 Portable Power Quality Analyzer, developed in accordance with the power technology standards DL/T826-2002 and DL/T448-2002, is a compact, lightweight, and practical power quality analyzer. It is suitable for relay protection departments, power quality measurement departments, and all power-consuming units.
The LD-608 Portable Power Quality Analyzer is equipped with two high-precision clamp-on current transformers, 25A and 500A, enabling convenient diagnosis of whether the power metering device is functioning properly. It provides a clear display of the vector diagrams for three-phase voltage and current, and prompts the results of 48 metering device wiring judgments to ensure correct wiring. The analyzer can serve as an electricity usage checker and phase voltmeter to perform corresponding testing functions. It also allows for on-site measurement of harmonic content (2-32 times) of voltage and current, the test of electricity meters, and detecting methods such as users replacing nameplates and letter wheels for stealing electricity. This handheld power quality analyzer is designed with a high-capacity lithium-ion rechargeable battery and an RS232 interface, ensuring continuous use for up to 8 hours. It can communicate with a computer via a cable for data management and report printing. The portable analyzer is an excellent tool for assessing power quality.
