General Information:
Turns ratio test is very important in order to find out the transformer has the right ratio corresponding on its rated voltage in primary and secondary. EPTTR-C is three phase, automatically test set specially designed for turns ratio, group test, PT and CT polarity measurements of power, distribution and instrument transformer.

Features:

• ♦ High speed and high accuracy because the total output is three-phase sine inverter, output voltage could adjust automatically, and soft start or soft stop function is equipped.
• ♦ Include three-phase transformer, single-phase transformer, PT, Z-type transformer turn ratio, group and polarity checking test function.
• ♦ Blind test function, which is testing transformers turns ratio or group without knowing high or low voltage connection methods.
• ♦ Angle differences test included in single-phase test.
• ♦ The maximum testable position of tap position is 197.
• ♦ The widest test range up to 10000.
• ♦ High and low voltage reverse connection protection function.
• ♦ Output short-circuit protection function.
• ♦ Clock and date display without power consumption; data storage methods consist of native storage and USB flash disk storage. Native storage could store 500 data which can be transfer and restore in USB flash disk; the data of USB flash disk is Word format, which can be edited and printed on the computer.
• ♦ The function of thermal printer, fast and noiseless.
• ♦ Small size and light weight.
