Description
Overview
GAOTek handheld voltage harmonics meter and tester has the following advantages: fundamental phase measurement endows it with strong anti-interference ability, displays three-phase voltage and current waveform in real time, 2 to 50 times harmonic ratio and histogram and analyzes power quality, equipped with Bluetooth and USB interface, more functions can be expanded by using the online APP. It is a new generation of instruments for field inspection of secondary circuits in electric energy metering and relay protection of power systems. It is also widely used in electrical equipment manufacturing, petrochemical industry, iron and steel metallurgy, railway electrification, scientific research and teaching and other departments.
