TA: Transformer Connection System, TCS – open for registration!

The live e-lesson titled Transformer Connection System, TCS, will be held on 10 March 2021 at the Transformers Academy, authored and presented by Stephan Hoffarth. If you want to attend it, click here.

If you miss it live, soon after the live event is over, the lesson will be available on demand.


Based on the inner cone plug system, TCS is a reliable alternative to connect your power transformer to the medium voltage grid.

TCS connects up to 3 medium-voltage cables equipped with size 3 inner cone plugs to oil-filled power transformers.

In this e-lesson we will give you a general overview of pluggable transformer connections, their application and distribution and under which conditions our new bushing TCS, which is based on the inner cone plug system, might offer you some advantages.
