ZBC-1 Automatic Variable Ratio TesterDetailed product description：

The ZBC-1 transformer ratio automatic testing adopts the latest microcomputer technology and high-precision A/D technology, which has the characteristics of high-precision, fast calculation, and artificial intelligence. The instrument can automatically measure the transformation of the tested transformer (or voltage transformer), and calculate the transformation ratio and error based on the pre-set wiring group (such as Y/D, etc.) and rated value. It can be displayed directly in digital form without manual calculation, making the transformation ratio testing accuracy and resolution reach 1-2500. It is an upgraded product of the QJ35 transformation ratio bridge, an essential instrument for transformer and transformer manufacturers and power system maintenance and testing departments.
