Digital Turn Ratio Meter (DG-TTE-617M) is designed to measure Turn Ratio of power and distribution transformers. The instrument uses ratio metric method for measurement to achieve high accuracy. The instrument is over load and short-circuit protected electronically. The unit offers a measurement range from 1.000 to 199.99 in two ranges i.e.19.999 and 199.99 with digital display. The instrument is direct reading type and no balancing is required. Stable sine wave is generated and fed to L.T. of transformer under test (‘X’ transformer). It uses four wire method to excite LT to compensate for any line drop.

The phase and the amplitude of H.T. output of ‘X’ transformer are measured and displayed digitally. The unit is provided with a keyboard to enter serial no of the transformer under test along with information of the phase under test. The data is stored in the memory of the unit capable of storing 500 set of data.

The unit is 12V battery operated and built-in battery charger along with 12V, 4.5 AH Maintenance free batteries which are provided for field use. The unit is provided with serial RS232 port to enable stored data transfer to PC on command. The data may be imported in Excel for further analysis.
