Description

Turns ratio is necessary test itme in transformer production/shipping/maintenance to check in case of transformer internal short-circuit/open circuit/wrong wiring, internal fault and contact issue of regulation switch. ZNX design and produce fully auto transformer ratio group tester which is easy/simple operation, powerful functions, and for the turns ratio of all big/middle transfromers.

Features:

• Kind interface, easy operation.
• Big turns ratio range：*****9.9 .
• Powerfull function：test for single-phase, *-phase winding auto test, one time test the turns ratio/error/group of phase AB/BC/CA.
• Quick test speed.
• One time test, auto cut off power.
• Customized data setting, auto storage test data for looking up.
• On-load transform ratio, only keyin turns ratio one time.
• Easy hand carry for field application.
