Fast TTR Testing with the Megger TTRU3

Want Fast TTR Testing and Light, Compact Equipment?

The Megger TTRU3 is the choice.  The TTRU3 is the lightest 3-phase test set on the market at just 14 lbs.  It is also small at 16” X 12” X 8”.  TTRU3 utilizes a revolutionary patent-pending 3-phase step-up ratio design to achieve its compact, lightweight footprint.

All tests are performed with one instrument, with just one 3-phase lead-set connection.  The universal lead-set allows easy connections to any transformer. In addition, the color-coded lead-set includes kelvin clamps that extend up to 3”, which is large enough for any bushing size.

The patent-pending 3-phase step-up testing removes the inaccuracy associate with test voltage as compared to its 1-phase predecessors. As a result, the operator does not need to know the proper test voltage to obtain a valid test result.

In addition to fast testing of all transformers, the TTRU3 can:

• Confirm expected nameplate configuration
• Measures actual versus expected phase shift
• Provides turns ratio %error vs. nameplate
• Provides guaranteed accuracy +/-0.05% from -20C to +50C

Does your transformer have an OLTC?  If so, you will appreciate the One Touch OLTC control.  One-Touch OLTC allows you to run through an entire OLTC with one click.
