JYT Transformer Turns Ratio Tester (F) General Introduction
JYT Transformer Turns Ratio Tester (F), this instrument adds a measurement mode for transformers with a neutral point, enabling measurement of the turns ratio of each phase (non-converted), facilitating manufacturers in diagnosing transformer faults.
Function Introduction
● The interface adopts an intelligent touch control method, making operation simple and convenient. The circuit uses a new generation of all-digital solutions to ensure long-term stability of the instrument
● Equipped with current testing function, making inter-turn short circuit detection more sensitive
● Fast testing speed, a single connection can complete three-phase turns ratio testing in just 10 seconds
● Suitable for turns ratio measurement of distribution transformers up to 1000KV transformers, current transformers (CT), voltage transformers (PT), and Z-connection transformers
● Non-volatile clock and date display, can store 50 sets of data internally, data is not lost on power failure
● Large screen color LCD display, clear and easy-to-read data, thermal printer printing, RS485 communication interface and USB storage interface
● The instrument has high and low voltage reverse connection protection, transformer short circuit and inter-turn short circuit protection, and protection against accidental connection to 380V power supply
● Working power supply: AC220V±10%, 50/60Hz±1Hz AC power supply
● Optional working power supply: external AC220V and internal battery for AC/DC dual-use power supply (optional according to user requirements)
