KDZD2030 three-phase multi-function phase voltammeter takes into account the three-phase multi-function phase voltammeter, harmonic tester and other functions, is a cost-effective electricity inspection and inspection equipment. Applicable to electric power, petrochemical, metallurgy, railway, meteorology, industrial and mining enterprises, scientific research institutions, metrology departments, etc. Especially electricity inspection, power supply, metering, scheduling, relay protection and many other departments commonly used testing tools.

Functional characteristics
Can measure single-phase, three-phase AC voltage, current, active power, reactive power, phase, phase sequence, power factor, frequency and many other power frequency parameters.
The single and three-phase AC voltage and current RMS values tested are all true RMS values, which are not affected by waveform distortion.
According to the tested electrical parameters, we can judge the wiring group of the transformer, the inductive capacitive load, test the secondary loop and the differential protection system, read the phase relationship between the differential protection CT, and check whether the wiring of the energy meter is correct.
10A range, the minimum 0.3mA (10A range) can measure the Angle value, convenient for a variety of light load or transformer no-load operation occasions.
It can visually display the three-phase voltage and current vector diagram, and intelligently distinguish the wiring results of 96 kinds of three-phase four-wire and 48 kinds of three-phase three-wire metering devices.
The display mode of vector diagram includes metering mode and relay mode, and the phase display range is 0° -360 ° and
-180° -180°, convenient for users with different habits.
It can display the waveform diagram of voltage and current, and measure the harmonic content and waveform distortion within 56 times.
Phase measurement can be carried out to measure the phase Angle relationship between each voltage and current in real time.
The ratio, ratio difference and Angle difference of low-pressure CT can be measured.
Built-in 32MB Flash memory, the instrument can be regarded as a 32MB U disk.
Can save the test results, including meter information, voltage, current, power and other electrical parameter information, vector diagram, wiring inspection results, 56 harmonics and other calculation results. It can save more than 30,000 pieces of data.
3.2 "TFT true color 320×240 LCD screen, color ICONS all Chinese display, intuitive and convenient operation.
Built-in high energy lithium-ion battery, long life, easy to use.
