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.

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.
