AC current sensors

17 August 2011 Passive Components

Pulse Electronics has rolled out its new Sidewinder range of AC current sensors. Sidewinder products differ from traditional current sense transformers because they do not need a core, which contributes to making them lighter, easier to assemble and less expensive.

The sensors provide a highly linear output voltage over a wide dynamic range from 0,1 to 1000 A, making them well suited for applications such as distributed power generation, renewable energy and storage, load balancing, power monitoring, advanced metering infrastructure (AMI), circuit breaker panels and smart meters.

The current sensors have a phase error of <0,05°, a 100 kHz bandwidth and a low temperature coefficient. They are based on the Rogowski coil principle and their segmented winding approach allows for a high number of winding turns per unit length to provide a sufficiently large output voltage for detection and integration.

Sidewinder products meet the 0,2% accuracy limits defined by the IEC 62053-22 and ANSI C12.20 standards for currents from 0,1 to 200 A and above as well as the Class 1 requirement for immunity to external magnetic fields. They are immune to external AC magnetic fields and DC magnetic fields. The addition of a Faraday shield over the winding prevents electrostatic coupling from the AC voltage of the primary conductor and acts as an effective barrier against external electrical fields associated with nearby current carrying conductors.

Although the standard sensor is round, as are traditional sensors in the industry, because Pulse’s sensors are not based on the traditional toroid core (round) shape, but on a coil configuration, the sensor can be made in several shapes and thicknesses in addition to the traditional round shape. The AC current sensors are supplied in trays, but other packaging options are available.
