The use of air transformer in the measuring current transformers in the electric power industry

Kazakov Mikhail Konstantinovich

The article proposes to use a device based on the air transformer (Rogovsky belt) and an integrator to measure alternating currents of industrial frequency in the electric power industry. The errors introduced by the Rogovsky belt due to its difference from the ideal integrating circuit are investigated, the ways of their reduction are considered.
