Interesting facts about: Transformers, induction, transformer physics, inrush current avoidance

Calculation of cables and fuses for control transformers with and without inrush current limitation

For low inrush current EI transformers at 230V primary = Table 1.
For low inrush current EI transformers at 400V primary = Table 2.
For transformers with hoh. Inrush current at 230V primary = Table 3.
For transformers with high. Inrush current at 400V primary = Table 4.

Inrush current limiters other than TSR or none

Examples of other inrush current limiters

Transformers switched on directly, without ESB or TSR

Measurement of the inrush current when transformers or switching power supplies are switched on directly with a contactor

TSR as zero-voltage switching hybrid relay, TSRL modified

A TSRL can also be supplied as a zero-voltage switching hybrid relay

Contactor contact bounce reduced with TSRL control of contactor coil

If a contactor with an AC coil is controlled with a TSRL, the contact bounce of the contactor is significantly reduced.
