Description
Model TTR 771 Transformer Turns Ratio Test Set

Model
TTR 771

Application
　TTR 771 is designed for high-end customers which date upload & analysis functions is required. TTR771 is usually positioned at electrical test vehicles, and controlled by one compute with other test instrument. It is also one part of transformer test table together with transformer resistance tester, transformer  tap change test set. and so on.
Product Features:
　　Test range wide, the highest can reach up to 10000.
　　Accurately measures ratio, phase deviation and exciting current
　　highest accuracy can up to 0.1%
　　Suitable for single phase, three phase and Z-shaped connection transformer.
　　Fast test speed, completion TTR test of three-phase transformer within 11 seconds.
　　Blind test for turns ratio and groups.
　　8 output terminals, including neutral point
　　Data display, storage and output
　　      LED display test procedure and data.
　　      Data printing
　　      480 groups of data storage
　　      RS485 for PC remotely controlling the instrument
　　      USB port for exporting the test data to U disk
　　Protection
　　      Wrong connecting protection for High-voltage terminals and low-voltage terminals.
　　      Wrong connecting protection for 380V input power supply
　　      Short Circuit protection for both transformer and its turn-to-turn.
　　Small size, light weight.
