Variacs, Auto-, Vario- and Isolation Transformers – Isolation, Day 28

I give a short introduction to the differences between autotransformers, variable autotransformers and variable transformers. I show my collection of 7 variacs/variotransformers in the range from 1x260V @ 2A to 3x400V @ 25A along with a 3x400V 10kVA isolation transformer.

Hardware, Materials, Salvaged Fittings and Much More – Isolation, Day 26

Mounting hardware, fittings, insulation materials, acrylic, fibre-glass, bits and pieces. All salvaged from machines, equipment and other high voltage related material, to be reused in my own projects and experiments. I started spring cleaning my work shop and I have come across so many components in various bins, boxes and drawers that I finally had some time to get it sorted and put together in groups.

Salvaged IGBT Bricks From Power Electronics – Isolation, Day 18

Over the years I have collected a great deal of salvaged IGBT bricks from the different power electronics I have taken apart. It have primarily kept 50+ Ampere rated bricks, single or half-bridge modules and 3 phase modules without builtin protection. It mostly comes from UPS, motor drives, welders or x-ray generators.
