Turns Ratio Meter
The HZTTR80A transformer ratio test set is a fully automatic testing device. It integrates functions for testing turn ratio, voltage ratio, vector relationship, winding connection group, polarity, tap position, and excitation current. This tester is a lightweight and portable instrument, with both the tester and its accessories housed in a multi-functional engineering plastic case that is resistant to cold, heat, moisture, and shocks, making it suitable for field tests. The test set can be used to test single-phase and three-phase transformers, both with and without taps. The instrument can be controlled entirely through a dedicated APP downloaded on an Android smartphone or tablet, facilitating the storage and upload of test data for easy retrieval.
Its main business is the production, manufacture and sales of electrical equipment and testing instruments.

Main Features
▪ Capable of PT ratio and polarity testing.
▪ Equipped with blind test function to accurately measure transformer ratio and winding connection group even when the connection group of a three-phase transformer is unknown.
▪ Capable of testing autotransformers, Z-type transformers, and phase-shifting transformers.
▪ Includes tap mode settings to accommodate transformers with high voltage at high tap positions and low voltage at high tap positions.
▪ Incorporates low-voltage side tap settings for transformers with taps on the low-voltage side.
▪ Features graphical display settings for more intuitive readouts.
▪ During three-phase transformer testing, can simultaneously measure the ratio of all three phases, resulting in faster test speeds.
