Transformers

A transformer is a central component of electrical engineering and consists of at least two windings. In the simplest version, these are wound from insulated copper wire and are located on a common magnetic core. A transformer converts an input AC voltage into at least one output AC voltage, where the ratio of input and output voltage corresponds to the ratio of the number of turns of the windings.

Mains transformers

Even though the mains transformer is nowadays often replaced by switched-mode power supplies in power supplies, it is still a simple, low-interference solution for voltage matching or voltage supply. The mains transformer is reliable, does not cause EMC problems and has a good efficiency. We achieve these very good properties by using high-quality primary materials and an optimal design.

Isolating transformers

An isolating transformer is a special type of transformer in which the primary and secondary sides are safely separated by a so-called protective separation. This separation is achieved by means of reinforced or double insulation, which becomes mandatory especially as soon as touchable extra-low voltages are involved. An isolating transformer is often also a mains transformer with a transformation ratio of 1:1, whose windings are safely separated.

Control transformers

If a control circuit is required that is galvanically isolated from a main circuit, a control transformer is used. This is a special form of safety transformer. In the event of a fault, control transformers attenuate the magnitude of the short-circuit current and make it possible to operate auxiliary circuits ungrounded. They also serve to adapt the power supply system to the equipment of the respective control cabinet.

Primary voltage: 1 V ... 690 V
Secondary voltage: 1 V ... 1.000 V

Leakage field transformers

Unlike the classic transformer, where the primary and secondary windings are as close to each other as possible, the leakage field transformer has a high degree of spatial separation. The resulting increase in magnetic leakage flux and loose magnetic coupling have the advantage that harmonics are filtered out. Thus, the function of a current-limiting choke and a transformer are combined in one component.

Technical specifications

Rated power: 30 VA ... 600 kVA
Primary voltage: 10 V ... 690 V
Secondary voltage: 1 V ... 1.000 V
Rated current: 10 mA ... 1 kA

Dielectric strength: up to 10.000 V

 

Examples

Designs

  • Core shape: E, EI, WEI, M, UI, EE sections.
  • Core material: grain oriented and non-grain oriented electrical steel sheet
  • Winding material: wire, flat wire, stranded wire in copper or aluminum

Other transformers

In addition to the transformers shown, the Pikatron Group also offers all other transformer types. In some cases only the terms differ, but in others these are genuine special cases, for which we can of course also help you. In all probability we can also help you with discontinued transformers of other manufacturers, if your application does not permit a fundamental renewal. But we are also at your disposal for updating your entire application. Just contact us.
