1.3 Features

Apply the newest principle of multi point DC method and meet the standard of IEC 44-6

The voltage measurement of ratio and phase displacement complies with standard of IEC
61869-2.

Measure ratio differential and angle differential accurately. The max ratio differential error is
±0.1%, max angle differential error ±3min and the ratio measurement range is 1~30,000.

Calibration certificate approved by National Center for High Voltage Measurement. The report
includes: angle differential, ratio differential test and stability test.

8.4 inch LCD with colorful graphical interface for HMI.

The whole integration structure, anti-vibration and anti-electromagnetic interference
combination chassis.

Built-in computer for operation. All test items are completed automatically.

Light weight and small dimension due to small voltage and power output.

The voltage measurement is used to test the bushing CT and GIS CT that can’t be measured
by traditional way.

The knee point voltage of CT ranges from 1-45,000V. And the excitation characteristic test
speed is fast. These features surpass that of traditional analyzer.

Apply to various types of CT (including TP type) excitation, ratio, polarity, secondary winding
resistance, load, ratio differential and angle differential etc steady-state or transient
characteristic test.

Automatically test knee point voltage/ current, ALF, FS, Ts, and Kr etc CT parameters.

Users can select ten groups of excitation data to save.

It lists the ratio error and phase error table and changes the report data in condition the rated
current 1%-300% be set.

The PCT automatically memories test items, report items, and report setting items.

The report can be converted into EXCEL format locally. More than thousands of reports are
saved in it for checking and printing.

Users can export the test results by U disk as well as upgrade.

The report tool software is convenient for report saving, converting and analyzing which is for
data contrast, judgment and assessment.
