Split-Core Current Transformer

Split-core current transformers are the most practical and safest solution for current measurement in existing installations. These transformers can measure current without disconnecting the cable, making them especially critical for energy systems where power interruption is not possible.

They are manufactured with a high-permeability ferromagnetic core, low-loss winding structure, and high-quality insulation materials, ensuring both high measurement accuracy and electrical safety. During operation, the transformer can be easily mounted around the cable inside the panel without any intervention to the energized circuit.

This product series, developed with Altinsoy Energy’s engineering expertise, provides not only practical installation, but also measurement reliability, data accuracy and uninterrupted system operation.
