Data is being organized .....

1. Only simple numerical settings are needed: set a higher test voltage and current, and the device will automatically step up from zero. The entire testing process automatically records data and automatically depicts and displays the volt ampere characteristic curve, eliminating the tedious labor of manual voltage regulation, manual recording, organization, and curve drawing. Quick, simple, and convenient.

2. Fully functional for testing CT/PT: "volt ampere characteristics", "5%, 10%, and 15% error curves", "transformation ratio, polarity", "angle difference, ratio difference", "secondary resistance" and "secondary load", "secondary circuit", "secondary withstand voltage", demagnetization function. Built in functional status description, no manual required, easy to operate and master.

3. High output voltage and large capacity: volt ampere characteristic test: 220V single machine output voltage up to 1000V, variable ratio test, current output up to 600A. The equipment power output is all true voltage and current values, and the waveform is a standard sine wave with a frequency of 50-60Hz; it can truly and effectively simulate the real state of the transformer, in compliance with relevant national maintenance regulations. The voltage regulation resolution can reach 0.15V.

4. Large screen fully localized graphical interface, rotating mouse operation: During testing, the volt ampere curve graph is directly displayed, and the coordinates are automatically scaled, which is clear, beautiful, intuitive, and convenient. The panel comes with a printer that can print curve graphs and test data at any time. The operation is carried out using our company's unique photoelectric rotating mouse. Various conventional controls such as panel buttons, switches, and control knobs will be removed. The operation is very convenient and simple, just turn left, right, and click to complete all operations.

5. Complete additional functions: equipped with large capacity storage, can store 2000 sets of test data, and data will never be lost in case of power failure; It has complete functions such as data query, browsing, printing, and clearing. Automatic calculation function for turning points, and printing function for filtering experimental data. Backlight software adjustment function; Comes with date/time function. Equipped with an RS232 communication interface, data can be uploaded to a computer for storage, display, editing, and printing. Equipped with a USB interface, data can be uploaded to a computer for storage, display, editing, and printing. Single machine integration, lightweight, weighing only 20Kg, easy to carry, and convenient for mobile testing.
