Megger TTR100 Series Hand-held Single Phase Turns Ratio Test Set
The Megger TTR100 is an automatic handheld, battery operated transformer turns ratio test set used to measure the turns ratio, excitation current, phase displacement, dc resistance and polarity of windings in single- and threephase distribution transformers (tested phase by phase), potential & current transformers, and tapped transformers. Deviations in the mentioned measurements will quickly indicate problems in transformer windings or in the magnetic core circuits.
The unique design of the TTR100 allows the user to operate the test set while holding it in one hand. No other transformer test set offers this capability. It effectively eliminates the user from having the kneel or bend down to operate the instrument and speeds up testing time. |

Megger 550005B Single-Phase TTR, hand cranked Transformer Turns Ratio Test Set
The 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 single-phase model is available in either hand-cranked or line-operated versions and measures highly sensitive turns ratios of up to 129.99:1 with accuracy of ±0.1%. An optional auxilary transformer extends the ratio range to 329.99:1. |
