Selec Current Transformer | Selec Current Transducer

Selec current transformers are instrument transformers used to reduce high alternating currents to measurable secondary values safely for instrumentation. They operate on electromagnetic induction principles, producing a proportional secondary current, typically standardized to 1 A or 5 A, which allows metering, protection relays, and control devices to measure line current without direct exposure to high primary currents. Selection is based on primary current rating, secondary current rating, accuracy class, burden capacity, core type, insulation level, mounting method, window or bar configuration, system voltage, and compliance with electrical measurement and protection standards for industrial power systems. Selec current transformers are electromagnetic current sensing devices, ring-type or bar-type in structure, classified by accuracy class and application category, interfacing through standardized secondary current outputs for integration into industrial metering, protection, and automation architectures.
