EPHIPOT EPTTR-C Transformer Turn Ratio Tester (0.9～10000)

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.
