Educational unit ETT-120
By means of the templates (12), and connectors (never more than 9), the following three-phase transformer confi gurations may be obtained:
- T-E-1 Template: Triangle-Startime phase difference 1
- T-E-5 Template: Triangle-Startime phase difference 5
- T-E-11 Template: Triangle-Startime phase difference 11
- T-2E Template: Triangle-Double Star
- T-T-0 Template: Triangle-Triangle-time phase difference 0
- T-Z-0 Template: Triangle-Zig/Zag-time phase difference 0
- E-E-0 Template: Star-Star- time phase difference 0
- E-E-6 Template: Star-Star- time phase difference 6
- E-T-5 Template: Star-Triangletime phase difference 5
- E-T-11 Template: Star- Triangletime phase difference 11
- E-Z-5 Template: Star-Zig-Zagtime phase difference 5
- E-Z-11 Template: Star-Zig-Zagtime phase difference 11
The input/output terminals are printed on all the labels. Each one of the six secondary windings is fi tted with a thermal protection circuit with a light indicator, set at 0.65 A.
Required accessories:
- TRI-120 three phase transformer didactic module.
DESCRIPTION
Equipment for analysing the different types of connections on three-phase transformers.
It is composed of an ETT-120 three-phase transformer multitemplate unit and a set of 12 templates.
The unit incorporates three single phase transformers, each of which has two secondaries of an identical transformation ratio (0.5/1). The nominal voltage for the primary windings is 22v and 11V for the secondary ones.
