ASG 123

Tube current transformer, poured out

Current transformers of the ASG 123 series are single-wire low-voltage current transformers. A fully encapsulated measuring system, as well as a newly developed fastening system for fastening the transducer on the power rail, enable the transducer to be used in the event of increased mechanical stresses, such as are encountered in operation close to a generator. The materials used to manufacture the transducers allow a wide range of operating temperatures, as well as the highest degree of climate resistance and electrical safety.

The modular housing system allows space-saving integration of up to three different measuring systems in one housing.

Due to the flexible length of the secondary connection cables, which can be defined when ordering, a time-saving assembly of the converter is possible without additional wiring.

All cable ends are provided with end sleeves, as well as a clear connection marking that corresponds to international standards.

To protect against mechanical damage to the insulation of the connecting cables, they are covered with an additional braided hose.

These current transformers are made specifically to your needs.

We offer a primary current range of 1000-4000 A, as well as a secondary current of 5 A or 1 A as standard, whereby further values ​​can be realized on request. This current transformer is available in the measuring transformer classes:

0.2, 0.5, 0.5s and 1 as well as in the protection converter classes 5P10, 10P10, 5P20 and 10P20. The production takes place in accordance with the in the DIN EN 61869-1 / 2 and VDE 0414-9-1 / 2 specified technical requirements.
