Overview

HZBB-10B Intelligent Tester of Transformer Ratio and Connection Groups adopts popular ARM processor, 168M frequency, 128M memory available to be extended to 4G memory card. The LCD screen adopts 5-inch high-definition color touch screen, combined with emwin display, making the tester interface simple and user-friendly in full touch screen and non-keyboard operation. The tester supports database and can be exported from the USB drive or through the data cable to the background computer.

Elaborate and compact design, unique thinking, makes the tester superior and powerful with small size and light weight. The tester uses a programmable signal source, can output single-phase, two-phase or three-phase standard Sine signal or high-frequency Sine signal, with adjustable output phase frequency. The tester adopts the new algorithm developed by our company to measure the ratio of three-phase transformer and ensure the measurement accuracy without adjusting the balance of the three-phase power supply. Therefore, the transformer ratio and wiring method can be measured in about 3 seconds.
