General Information:
EPTTR-E Automatic Transformer Turns Ratio Tester is used to measure the turns ratio or voltage ratio of power transformers and voltage transformers, and can meet the tests of transformer production, installation, operation, and power preventive test procedures.

Features:

-Precision inverter three-phase measuring power supply is adopted in the tester to measure more accurately.
-Adopt three-phase output voltage, three-phase pressure, three-phase simultaneous measurement, improve test speed, and automatically identify transformer wiring group.
-Applicable to a wide variety of transformers, especially for the Z type transformer, rectifier transformer, grounding transformer, furnace transformer, phase shift transformer, balance transformer and other transformer testing, measurement parameters are the most comprehensive.
-The use of precision three-phase inverter power supply, with high and low voltage reverse polarity protection, transformer inter-turn short circuit protection, on-off tap-changer not in place protection, the output short-circuit protection, which increases tester stability.
-After inputting the rated parameter, it can automatically measure the transformer ratio value, error value and on-load tap-changer position.
-65K true color LCD, modular liquid crystal display.
-Can be equipped with both print output, USB port and RS232 port.
