Features

• 7 inch TFT color LCD screen, intuitively display data, menus and vector diagram.

• Year, month, day, week and clock display function, real-time display of date and time in saved data.

• Output two test voltages, low voltage test mode can provide larger excitation current, which can meet the test requirements of different transformers.

• Memory expansion 8 G memory card, can store massive test data.

• Data can be exported through USB flash drive or transferred to the computer through data cable, and can be opened directly on the computer.

• Supports editing such as creating folders, file names, renaming files, opening files, deleting files, browsing files, etc., which is convenient for data management.

• High degree of intelligence, various interface intelligent reminders, easy to operate.

• Automatically generate a three-phase standard sine wave with stable amplitude and constant phase or a two-phase standard angle difference of 90 degree power supply.

• It has over-current protection, temperature protection, reverse connection protection and other functions.

• When measuring a three-phase transformer, the standard three-phase sine wave power supply output is a true three-phase simultaneous measurement.

• The test output waveform is displayed to facilitate the judgment of the test status.

• It can output single-phase, two-phase and three-phase voltages, performing single-phase measurement, realize automatic testing of three-phase winding and measurement of other types of transformers, and the connection group can be selected arbitrarily.

• The transformation ratio, error, angle difference, current gear, current transformation ratio, connection group and phase diagram of the three phases of the transformer are measured at one time and displayed on the same screen.

• It has a blind measurement function and is not constrained by the internal structure and external center point of the transformer.

• The measurement speed is fast, and it only takes about 10 seconds to measure three phases at the same time.

• After one measurement is completed, the test power supply is automatically cut off.

• Set the rated voltage of the high and low voltage sides of the transformer and automatically calculate the standard transformation ratio value.

• When measuring a loaded transformer, only need to set the parameters once to automatically calculate the tapping gear and current transformation ratio.

• Easy to carry and suitable for field operations.•
