Hzttr80A Three Phase Automatic Digital Portable Power Transformer Test TTR Meter Turns Ratio Tester Price

I. Product Overview
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.
