■ Functional features
▲ True three-phase test: single-phase power input, internal digital synthesis of three-phase standard sine wave signal, three-phase power output by high-power amplifier, distortion is small, high stability, phase symmetry is very high, the test results have better equivalence, there will be no group misjudgment and other phenomena.
▲ Can be single-phase measurement, and can realize the automatic test of three-phase winding, single-phase, three-phase can measure polarity, phase Angle, a complete measurement of AB, BC, CA three-phase variable ratio, error, tap position, tap value and other parameters, can be automatic identification group number.
▲ Simple operation: no need to choose wiring mode, no need to choose wiring groups, measuring Y/△, △/Y transformer without external short connection, can automatically switch wiring mode according to the selected test content.
▲ Tap test: can quickly measure the change ratio and change ratio error in each tap switch position, rated change ratio only need to input once, do not have to repeatedly input can calculate the change ratio error of each tap position.
▲ Can use the built-in rechargeable battery as the working power supply, there is no need to find the working power supply on site. (Optional function)
▲ In the variable ratio measurement of the introduction of the concept of measuring phase Angle, can measure the high pressure side and low pressure side of any Angle of the phase Angle.
▲ Can be single-phase transformer, three-phase transformer, z-type transformer, rectifier transformer, Scott transformer, inverse Scott transformer and other types of transformer ratio, group (phase Angle) test.
▲ Use 7 inch hd color screen to display data effect and vector image effect intuitive and delicate.
▲ The voltage, current between the size and phase relationship with vector diagram intuitive expression, the user can be more easily from the subjective understanding of the actual significance of each parameter.
▲ The instrument used test source is digital synthesis of standard sine digital source, distortion is small, not affected by the working power supply.
