High voltage transformer up to 40 kVCast resin high voltage transformers up to 40 kV


Description


Test transformers are used to generate high, distortion free voltages at relatively low power. Because of that high voltage test transformers differ from power transformers in construction and dimensions. Test transformers are one-phase constructions and they have a high winding ratio. As a result of high voltages that have to be insulated comparatively huge isolation spaces are needed and as a consequence high magnetic stray fields resp. high short circuit voltages Uk occur. The iron core is constructed in a way that makes the flux density roughly remain in the linear area of the characteristic magnetisation diagram. Cheap sophisticated and environmental-friendly substitution for oil-immersed transformers.


Fields of application


High voltage transformers are often used for test transformers e.g. for area insulating materials.
