The Importance of High-Quality Current Transformers

In modern energy technology, precise and reliable measurements are crucial for safe and efficient grid operation. Current transformers play a central role here, as they convert high primary currents into measurable secondary signals. The quality of these transformers has a direct impact on the accuracy of measuring devices, energy meters, and protection relays.

At CELSA Messgeräte, we place the highest value on the quality of our current transformers. Our products are developed and manufactured in Germany and are subject to the strictest quality controls. We offer a wide range of plug-on, winding, and split-core current transformers for a wide variety of applications in energy distribution and in the industrial environment.

Selecting the right current transformer is crucial for the accuracy of your measurements. Pay attention to the rated current, the accuracy class, and the design to find the right transformer for your application. Our experienced team will be happy to advise you on selecting the optimal product.

Measurement Technology Portfolio

Our product portfolio includes current transformers, summation transformers, signal transmitters, digital and analog measuring devices, energy meters, hour meters and shunts. This helps you build reliable end-to-end measuring chains for power systems and industrial environments.
