Rent the Megger TTRU3 from Protec Today
The Megger TTRU3 True 3 Phase Transformer Turns Ratiometer uses a revolutionary design to perform a complete series of measurements on a transformer, including 3-phase step up turns ratio testing.
Rent the Megger MWA330A 3-Phase TTR, Winding Resistance Analyzer
The Megger MWA330A 3-Phase Transformer Turns Ratio and Winding Resistance Analyzer is an advanced 3-phase transformer test system that provides complete ratio, phase and winding resistance measurements with only one 3-phase lead-set connection.
Once connected, the Megger MWA330A performs DC resistance measurements on all high- and low-side windings without reconnection. It has an 8-terminal/6-winding resistance measurement capability and doesn’t need any inter-connected boxes, allowing for testing on all 6 windings without having to disconnect and reconnect leads.

Rent the Raytech TR-SPY Mark III for Precision Laboratory Measurements
Transformers are simple devices in concept, with two coils of insulated wire wound in close proximity on an iron core (windings). One wire (primary) is connected to a power source, such as the utility or a generator. The other wire (secondary) provides power, “transformed” in some way, to the load. Energy transfer from one wire to the other is through magnetic induction.

Rent the Megger TTR310 to Test Difficult Three-Phase Transformers
The Megger TTR310 Three-Phase Transformer Turns Ratio Test Set is designed to measure the turns ratio of power, instrument, and distribution transformers in a substation or manufacturing environment. A rugged and robust design makes the instrument well suited for use in a variety of harsh environments.
The Megger TTR310 is ideal for use by power transformer manufacturers, as the test sets unique testing procedures and storage capability allows an operator to set up and test difficult three-phase transformers (with multiple tap changers and bushing CTs) in a fraction of the time than it used to take with other TTRs.
