The MICROTEST 9560 Transformer Integrated Test System is a comprehensive measurement system that integrates low-voltage electrical characteristics and safety compliance testing into a single platform. Controlled by a PC, it provides 20 test channels. The system integrates an AC source for dynamic testing of transformers (open-circuit voltage, excitation current, no-load power) and measures the inductance value of transformers. The optional LCR Meter offers test frequencies of 200kHz, 500kHz, and 1MHz.

The 9560 test system combines low-voltage testing for transformers with AC/DC withstand insulation testing and interlayer short-circuit testing. The low-voltage testing includes parameters such as inductance value, leakage inductance, DC resistance, AC resistance, quality factor, capacitance value, turns ratio, and checks for shorted terminals. The safety compliance testing offers AC withstand voltage up to 5000V, DC withstand voltage up to 6000V, and maximum insulation impedance of 12000MΩ. The interlayer short-circuit test utilizes non-destructive high-voltage pulse testing technology. It analyzes the damping attenuation waveform generated by L/C resonance to detect short-circuit defects between transformer coils or insulation layers.

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.



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.



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.

If the layer short happened, the waveform will tremble. Therefore, the instrument will quantize and compared it.
