CURRENT TRANSFORMERS

Key Advantages: 

– Standards: Designed per IEC 61869-1 (general) and IEC 61869-2 (current transformers).

– Voltage Levels : up to 36 kV outdoor CT classes (also oil-immersed or resin cast types)

– Primary Current Range: up to 2000 A in some outdoor CTs

– Secondary Current: 1 A, 2 A, or 5 A.

– Accuracy Classes: 0.2S, 0.2, 0.5S, 0.5, 1.0, 3.0, 5.0

– Rated Output (VA): 10–50 VA depending on rating and secondary current).

– Insulation & Withstand Levels:

– Power-frequency withstands: 34–50 kV for 15 kV class

– Lightning impulse withstand voltages 95–125 kV

– Construction Features:

– Epoxy resin casting for insulation with sealed terminals.

– Options for oil-immersed or dry resin designs
