3 Phase TTR

Product Description

Turns Ratio Test Set 

3 Phase Transformer Turns Ratio Test Set is designed to measure the Turns Ratio of Power, Instrument, and Distribution Transformers in a Substation or Manufacturing & Maintenance Environment.

TTR working function: Voltage is applied on the LV Winding and measured on HV Winding.

Ratio of Transformer measure by conducting at LV Winding and calculated by dividing the induced voltage on all tap positions reading into the applied voltage value. When ratio tests are being made on 3 Phase Transformers, the ratio is taken on one phase at a time with a 3 Phase TTR by rotary Selector Switch until the ratio measurements of all three phases are completed.
