The ART series provides the same ease of installation as existing split-core transformers, but with the benefits of being thinner and more flexible.
Whatever the chosen dimension - 50, 70, 125, 175, 200 & 300 mm diameter for the aperture – the ART can be mounted very quickly by simply clipping on to the cable to be measured. Contact with the cable is not necessary, and the ART ensures a high level of safety as well as providing a high rated insulation voltage (1000 V Cat III PD2 - reinforced).
The ART also allows disconnection of the coil to be detected through the use of a security seal passed through a specially designed slot, making it really useful when used with a meter. It can be used in applications requiring a protection degree up to IP 67.
This Class Accuracy 0.5 ART updated version completes the LEM City product solutions for the AC current measurement dedicated for future Smart Cities offering innovative and high quality solutions for measuring electrical parameters in Smart Grids and Industry 4.0.
Intelligent electricity network (Smart Grid) applications such as Power Generators, Medium Voltage/Low Voltage Substations, Sub-metering integrate more and more current sensors to ensure reliable integration of distributed renewable energy, energy storage, production and consumption. This leads to the implementation of more current sensors to allow control rooms to automate, to monitor remotely and share real-time data of equipment.
ART series current sensors are CE marked and conform to the IEC 61869 standard, as well as being covered by LEM’s five-year warranty.
