Testing of amorphous coupling transformers
Amorphous coupling transformers are used in the power supply systems of New Energy Vehicles (NEVs) and offer advantages such as low losses and high energy efficiency .
Solution details
Test requirements:
Check the following parameters of the coupling transformer:
- High voltage
- Insulation strength
- Winding insulation (interlayer testing)
- Low resistance
- Inductance values
The test unit is integrated into a standard control cabinet .
- Using an industrial PC , a module for measuring insulation resistance and leakage current , an inductance and low-resistance measurement module , and a power module, 4-channel products can be tested simultaneously .
