3-Phase Transformer Tester T-203, 0.05% Accuracy 0.8-10000 Ratio, USB RS232 Interface

Product Description

T-203AUTOMATIC THREE PHASE TRANSFORMER TURNS RATIO TESTER

The T-203 automatic transformer turns ratio tester(TTR tester) can measure the high/medium voltage (if any), high/low voltage ratio, and phase of various high-voltage transformers; Can adapt to the needs of various large, medium, and small transformer ratio tests (including zigzag transformers, rectifier transformers, electric furnace transformers, phase-shifting transformers, balance transformers, Scott and inverse Scott transformers).
The T-203 automatic transformer turns ratio tester(TTR tester) is equipped with a large capacity lithium-ion rechargeable battery and a highly stable three-phase variable ratio power supply. Color LCD display, graphical user interface, vector diagram display and wiring judgment. Store test data, with printer, PC data management software. Automatic load current protection to prevent damage to the instrument caused by excessive load or short circuit in the test circuit.

FEATURES

APPLICATION

Wide range of testing types: it can test various single-phase, three-phase, Zigzag, Scott, inverse Scott transformers.

It can also test Potential and current transformers ratio.

The starting voltage range for testing is optional: 160V/10V. The tester voltage can automatically downshift according to the transformer load during the testing process, with a minimum voltage of 1V, to meet various transformer loads.

 Wide testing range: Up to 10000.

Fast testing speed: Three phase testing can be completed in just 10 seconds.

 Intelligent blind measurement: It has the functions of blind measurement of ratio, group, and phase shift testing.

Strong testing function: it can connect high/medium voltage and high/low voltage terminals simultaneously.

 Complete protection: Short circuit and inter turn short circuit protection function.

 Human computer and interface: Non power down clock and date display, data storage, communication, and export functions, thermal printer.

 Self provided rechargeable battery: Easy to move.

 7 inch touch TFT color LCD.

Lightweight and easy to carry: small in size and light in weight.
