Automatic Portable Transformer Turns Ratio Tester TTR Meter

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. SXTTR automatically test set specially designed for turns ratio, phase shift and excitation current measurements of power, distribution and instrument transformer.

Features:

ØAuto measuring transformer connection groups (single phase, three phases).

ØAuto measuring transformer turns ratio (single phase, three phases).

ØAuto converting the group.

ØAuto switching phase sequence.

ØAuto switching measuring range.

ØAuto calibrating meter.

ØCT turns ratio could be measured, and to display exciting current.

ØAuto calculating relative error after input standard turns ratio.

ØAuto cut off test voltage after one test completed.

ØData setting, final data saved automatically, historical data can be browsed.

ØWhen test tap changer transformer, only need to input one turn ratio.

ØAuto identify GST negative connection and to give alarm.

ØAuto identify over current and to give alarm.

ØBuild-in protected circuit, to avoid transformer HV/LV negative connection

ØRS232 port could upload test report.
