Transformer Characteristic Tester

Transformer Loss Parameter Tester Main Function Brief

Transformer Loss Parameter Tester is a multifunctionalAll.FaceA stable performance electrical testing equipment, which primarily features the following testing functions:

Three-phase Short-Circuit Impedance Measurement

The tester can display key parameters such as three-phase voltage, current, and power.

The impedance voltage can be converted to the rated temperature and current, and compared with the impedance on the label, providing an error percentage.

Through the single-phase method testing of a three-phase transformer, potential defects in the single-phase of the transformer can be detected.

Single-Phase Short-Circuit Impedance Measurement:

In addition to measuring the short-circuit impedance of single-phase transformers and the percentage error compared to the rated impedance, the system can also measure the transformer's impedance, reactance, resistance, and inductance values, facilitating data comparison and analysis for users.

Zero Sequence Impedance Measurement:

This feature is particularly suitable for transformers with a star-connected primary winding and a neutral point on the high-voltage side.

The instrument can record zero-sequence impedance, zero-sequence reactance, zero-sequence inductance, impedance angle, and zero-sequence resistance, assisting users in analyzing the transformer's zero-sequence performance.

Load Loss Test:

The tester is equipped with the function to test the equivalent load of a three-phase transformer at low voltage.

By comparing the variations in load current and load losses for each phase, as well as their symmetry, the performance condition of the transformer can be determined.

No-load loss test:

The tester is capable of performing no-load tests on three-phase transformers.

By analyzing and comparing the no-load losses of each phase, the distribution of no-load losses in the iron core can be observed, revealing any local defects in the winding and iron core magnetic circuit, as well as determining if the transformer's iron core structure is loose.

When there is no three-phase test power supply or when performing defect analysis on the core column, the tester can also conduct single-phase no-load tests.

External Voltage Transformer Function:

When the test voltage exceeds the direct measurement range of the instrument, an external voltage transformer can be connected.

The instrument can be set for the ratio of an external voltage transformer, directly displaying the applied voltage value, thereby expanding the application range of the instrument.
