Product Description

Used for verifying and calibrating the accuracy of transformer ratio testers (ratio bridges)

The transformer ratio group tester calibration device is a standardized calibration instrument specifically designed for testing and calibrating transformers and current transformers. It complies with the GB1094.1-1996 "Power Transformers-Part 1: General Principles" and JJG314-2010 "Measurement of Voltage Transformers" calibration regulations, and is a specialized standard equipment developed to meet the calibration requirements of digital-type transformer ratio group testers.
The instrument performs ratio verification under 200V voltage, featuring seven decimal adjustment dials for customizable ratio settings. Three dials enable configuration of D/d, D/y, D/z, Y/d, Y/y, Y/z, and connection groups. Utilizing passive voltage ratio standards, it connects three single-proportion standards through switch combinations. The device offers simple operation, reliable performance, and strong anti-interference capability.
