Why do you need a transformer starting switch when building a transformer?

A major problem for transformer manufacturers is the high inrush current that occurs when a transformer is switched on. This current surge means:

  • Overloading the power supply: The high inrush current can blow fuses or trip circuit breakers, causing interruptions in the power supply.

  • Voltage dip: The sudden high current flow can cause a voltage drop in the supply network, which affects other connected devices.

  • Thermal load: The high current load can lead to undesirable heating of the transformer winding and other components, which shortens the service life of the transformer.

  • Mechanical load: The high inrush current can generate mechanical stresses in the windings and core of the transformer, which can lead to mechanical damage.

The integration of an inrush current limiter means that:

  1. Avoidance of inrush current: the transformer inrush current limiter avoids the initial inrush current, thus avoiding the problems mentioned above.

  2. Protection of electrical components: By avoiding the inrush current, the fuses, switches and other components are protected from overload.

  3. Extending the service life of the transformer: Less thermal and mechanical stress means a longer service life for the transformer.

  4. Stabilization of the power grid: The limiter prevents voltage dips and ensures a stable power supply, which is particularly important in grids with sensitive devices.

Overall, an inrush current limiter ensures the safe and reliable commissioning of transformers, minimizes downtimes and maintenance costs and contributes to the longevity of the systems.

As a transformer manufacturer, you can approve and sell your transformers with our product in accordance with the EN61000-4-11 standard. This standard is a prerequisite for electronic products used in medical technology.
