Product Description

General Information
GDRB-I Transformer Short Circuit and Impedance Tester is an automatic instrument specially used for testing power characteristic of big and small transformer. The measurement is accurate even when the testing voltage and current waveform have serious distortion or the tested transformer has very low power factor. Single-phase power or three-phase power is adopted and rated voltage is converted in low voltage test, which is suitable for on-site use.
Features
l 320*240 High definition LCD screen, to show multiple test parameters.
l Synchronously measure voltage, current, power, power frequency.
l Automatically record test data, built-in UPS storage and storage data for long time.
l Built-in printer, to print data quickly.
l High test accuracy, the test accuracy of current and voltage is above 0.1%.
l Strong anti-interference ability. With software digital filter and hardware anti-interference mixed filter technology, to make the test stability and anti-interference ability better than other instruments.
l Three independent voltage and current input channels. 16bit high AD converter is adopted for measurement channel.
l Transformer impedance value can be measured accurately even when the voltage and current waveform have serious distortion or the power factor is very low.
l All testing channels are isolated and independent, and range can be adjusted automatically.
l The change of external PT/CT to all the input channels can be set respectively. When input voltage is less than 600V and input current is less than 50A, it can test directly.
