HARTING differential current transformer for high functional reliability

HARTING Balance transformer 10 A

The one-piece core transformer for differential current measurement up to 10A is a new member of the HARTING current sensors program. Specifically designed for ambient conditions in the wind energy sector, it not only offers high functional reliability, but extremely high mechanical stability as well.

The differential current transformer permits the measurement of the current deviation in supply and return conductors or the monitoring of earth leakage currents in single or multi-phase power cables. The compact current transformer is designed for a maximum cable diameter of 110 mm and is suitable for the detection of primary nominal currents of up to 10 A with a conversion ratio of 1: 600. The transformer can be deployed for frequencies in the 5 - 400 Hz range.

The housing design is optimized for high holding forces of up to 250 kg and features an IP65 degree of protection acc. to  IEC 60 529. In addition, the proven HARAX® insulation displacement connection technology offers simple, quick and tool-free assembly.

The wide temperature range of -15° C to +55° C also permits use in thermal-critical applications.

As a result, high reliability and accuracy make the new transducer ideal for use in monitoring applications, as in wind power plants or industrial facilities, for example.
