Current transformers (CTs) and voltage transformers (VTs, or potential transformers, PTs) are essential components for AC power systems (50/60Hz). They convert high currents/voltages into standardized low-level signals (e.g., 5A/1A for CTs, 100V for VTs), enabling safe, accurate metering, relay protection and system monitoring.
Accurate Signal Conversion: Converts high voltages/currents to standardized signals for reliable metering.
High Precision: 0.2-0.5 class for metering; 5P-10P class for protection.
Durable Construction: Premium silicon steel cores and epoxy resin insulation ensure stability.
Versatile Designs: Cast resin, oil-immersed, and open chassis options available.
Global Compliance: Conforms to IEC 61869 and ANSI/IEEE C57.13 standards.
Superior measurement accuracy guarantees precise data for energy billing. Robust high-grade materials deliver excellent anti-interference capability in harsh industrial environments. These units isolate high-voltage circuits from monitoring devices, ensuring personnel safety.
