Megger’s TTRU3 transformer turns ratio tester is designed to perform three-phase turns ratio measurements using step-up excitation (patented). A single three-phase lead-set connection is all that is required to complete three-phase tests in less than 10 seconds!

The TTR provides accurate measurement of exciting current (to 0.1 mA) which can help provide information about the condition of a transformer’s core. Unwanted circulating currents or unintentional core grounds can increase the exciting current and indicate a problem. Phase Angle Deviation and its Application
