MICROTEST 3-in-1 Transformer Testing System (Low Voltage+Safety+Impulse)

20 Channels Transformer Tester

The MICROTEST 2-in-1 Transformer Integrated Test System is a comprehensive solution that combines low-voltage electrical characteristics testing and safety compliance testing. It offers 20 testing channels and integrates low-voltage testing (including inductance, leakage inductance, resistance, capacitance, etc.) with AC/DC withstand voltage insulation testing (up to 5000V/6000V). It ensures efficient and convenient testing for transformer products.

To measure the inductance value of a transformer, you can use an LCR meter, which offers selectable test frequencies including 200kHz, 500kHz, and 1MHz. It supports software that allows connection to a PC, enabling the storage of test data.

Area Comparison	When layer short happened, the loss of power on coil increase, the resonance damping coefficient increase, resonance amplitude decrease, the total area decrease. These are the basic parameters we check layer short. By calculating and comparing the deference of area between golden sample and DUT. Show by percentage Analysis the power loss by this data.
Area Differential	Add up the difference between normal wave and DUT wave call “Area differential”. When layer short happened, the inductance reduce(similar the transformer). The wave phase change and the area differential also change. This will show “fail” on the instrument. However, the parameter might cause deviation because of the deviation of inductance, resonance phase shift. (Silicon steel product such as motor and traditional transformer is not suitable) By calculating and comparing the deference of area between golden sample and DUT. To determine the degree of waveform overlap. Compare the inductance by this.
Waveform Comparison	Set a acceptable wave range, if the DUT’s wave is in this range shows “pass” otherwise,”fail”. This parameter can judge both amplitude and phase of resonance wave. This can increase the detection capability of layer short.
Corona	In pulse test, the insulation defect will cause discharge and create corona. This function is able to count the times that corona happened base on the degree of deviation. Detect the discharge phenomenon on the coil.
Flat	If the layer short happened, the waveform will tremble. Therefore, the instrument will quantize and compared it.
