ZXSBF Third-harmonic Generator

This test set is designed to meet frequency multiplied Induced Over-voltage Withstand Test requirements, which applied to testing of series excited High Potential Transformers with voltage system at 35-220kV.

It can evaluate the dielectric strength of transformers, carry on induced voltage test on mini transformer windings, or work as short time 150Hz power source.
