566-2565: 400:5 Ratio High Accuracy Differential Transformer

A High Accuracy Differential Transformer has two primary windings, one on each side, and a single secondary winding. When equal currents flow through the primary windings in opposite directions, they cancel each other out, inducing minimal voltage in the secondary winding. However, if a current imbalance occurs (leakage or fault), a voltage is induced in the secondary winding proportional to the difference in current between the primaries. It reduces the primary current by a factor of 80 in the secondary winding while maintaining precise current differential measurement.

Attributes:
• Continuous Thermal Rating Factor is 2.0 at 30° C and 1.5 at 55°C
• Relay Class: C100
• Plastic Current Transformer with secondary terminals having 2 studs and 2 washers of brass

Applications:
A High Accuracy Differential Transformer accurately measures high current levels in power systems and provides a stepped-down output for monitoring, control, and protection purposes.

• Material: Nylon, 6, 6/12, 6/6 Plastic
