KDZD2020 two-clamp phase voltammeter is another portable handheld multi-function instrument developed by our company for field testing. Intelligent, accurate, stable, power saving, safe. Beautiful appearance design, light weight, easy to operate. It is a cost-effective electricity inspection and inspection equipment. The instrument can easily measure the phase between U-U, I-I and U-I in the field, and can also indirectly measure the power factor and power of the circuit, distinguish the phase sequence of inductive and capacitive circuits and three-phase voltage, detect the wiring group of the transformer, test the secondary circuit and the parent differential protection system, and read the phase relationship between the differential protection group CT. Check whether the meter is connected correctly or not. 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.

3.2 inch 320×240 true color TFT LCD screen, GUI (graphical user interface) using enwin design, beautiful interface, easy to operate.
Current: 10A current clamp, minimum 0.3mA can measure the Angle value; Voltage: The minimum 1V can measure the Angle value. Convenient for light load or transformer no-load operation.
When measuring the phase between U1-U2, the two input circuits are isolated, thus avoiding the possibility of miswiring caused by short circuit of the line under test, which may burn the measuring instrument.
The reference signal of the vector graph can be flexibly and automatically selected for drawing according to the presence or absence of the signal.
The display mode of the vector diagram has a metering mode and a relay mode, and the phase display range is 0° -360 ° and -180° -180°, which is convenient for users with different habits, and intelligent discrimination of the wiring results and phase sequence of 48 kinds of three-phase and three-wire metering devices.
Can be equipped with a variety of range current clamp.
Automatic selection of voltage and current signal range, no manual operation, easy to use.
You can judge the capacitance and sensitivity of the circuit, and calculate the resistance, reactance, conductance, susceptance and other parameters.
The voltage and current waveform can be displayed in real time, and the waveform distortion can be measured.
Can display 2-57 harmonic content and bar chart, with power quality analysis function.
Through the setting of PT and CT, the secondary data can be converted to the primary side, and the voltage, current, power and so on can be displayed on the primary side.
The phase measurement data is processed on average, and the data display is stable, and there will be no abnormal display data at 0° and 360° critical points.
Can measure 4 input (2 voltage, 2 current) signals at the same time.
It can display the true RMS value, phase, power, power factor and other electrical parameters of voltage and current. The measurement results are displayed by vector graph, effective value, phase, power and so on.
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.
Built-in Flash memory, the instrument can be regarded as a U disk. 10000 sets of measurement data can be stored and viewed on the instrument.
