- Special transformers
Customer Pain Points
High test voltage
The generator must provide sufficient voltage and energy for the transformer under test.
Large test object capacitance
The generator and wave-shaping network must be matched to the test object.
Waveform distortion
The measuring and generating circuit must be designed to achieve the required impulse waveform.
Laboratory safety
The complete system needs appropriate grounding, interlocking, discharge and safety protection.
FAQ
Can you design the generator according to transformer capacity?
Yes. Generator parameters should be selected based on transformer voltage class, insulation level, test standard, capacitance and laboratory layout.
