Transformer Turns Ratio Test Set
The Megger (AVO-Biddle) Single Phase TTR Transformer Turns Ratio Test Set measures the turns ratio and exciting current of windings in power, potential and current transformers. Deviations in turns ratio readings indicate problems in one or both windings or the magnetic core circuit.
The TTR test set aids in identifying:
Shorted coils
Open circuits
Incorrect connections
Internal faults or tap-changer
defects in step regulators as well as in transformers
Each Unit Includes:
Cable Assembly
Two C-Clamps for X (low voltage) Windings, 10 ft. (3 m)
Two Spring Clips for H (high voltage) Windings, 13 ft. (4 m)
