ZERO-PHASE CURRENT TRANSFORMER

摘要

PURPOSE:To provide a zero-phase current transformer in which the performance for shielding the leakage flux from a primary conductor is enhanced without increasing the longitudinal dimension thereof. CONSTITUTION:The core 2 has a flat cross-section where the width A is longer than the height B. This structure does not increase the longitudinal dimension of a zero-phase current transformer 1 even if a sufficiently thick shield 4 for the leakage flux from the primary conductor is disposed in front and rear of the core 2.
