Special transformers

Slightly frequent connection groups (reversed V/v, Scott, Leblanc …)

Field of application:

All those applications in which is needed the interconnection of networks of different characteristics or the using of single phase loads departing from three-phase networks.

Multipolar groups of connection

Hexaphase with or without interphase transformer, dodephase …

Field of application:

All those applications in which it is needed to multiply the wavinesses like in the feeding of galvanic baths and UPS rectifiers.

Transformers of specific design for non linear loads (K-factor)
Field of application:

All those applications in which it is needed to feed loads with a high harmonic distortion (the normal transformers are not designed for this, and should provoke an excessive warming).

The following table is based on experimented practices. A transformer of K-13 factor solves almost all the problems that are present in the applications with a high value of Total Harmonic Distortion (THD).

Non linear loads K Factor
The electronic loads represent <5% K-1
The harmonics produced by the loads represent <35% K-4
The harmonics produced by the loads represent <50% K-7
The harmonics produced by the loads represent <75% K-13
The harmonics produced by the loads represent <100% K-20
Cnomo type

Transformers for automotion that included magnetothermics as protection.

cnomo
Transformers IP-54

Transformers with IP-54 degree of protection.

Special transformers protected against hostile environment, such as rain, dust and splash water. Single-phase and three-phase series.
