An internal screen is supplied as standard, protecting against external fields, which improves accuracy and optimizes performance for measuring small currents.
The ART series offers the same ease of installation as existing split-core transformers and adds the advantages of being thinner and more flexible.
Whichever size you choose – 50, 70, 125, 175, 200, and 300 mm diameter opening – the ART series can be mounted very quickly simply by wrapping it around the cable to be measured. Contact with the cable is not required, and the ART series ensures a high level of protection, as well as providing a high rated insulation voltage (1000V Cat III PD2 - reinforced).
The ART series also allows the coil to be disconnected using a tamper seal through a specially designed slot, which is particularly useful when used with a meter. It can be used in applications requiring a protection rating up to IP 67.
This updated version of ART with class 0.5 accuracy completes the LEM City product range for measuring AC currents and is dedicated to future smart cities by offering innovative and high-quality solutions for measuring electrical parameters in the Smart Grid and Industry 4.0.
Smart Grid applications, such as power generators, medium- and high-voltage substations, and secondary meters, are integrating an increasing number of current sensors to ensure the reliable integration of distributed renewable energy, energy storage, production, and consumption. This entails the deployment of more current sensors that allow control rooms to automate, remotely monitor, and share equipment data in real time.
The ART series current sensors are CE marked and comply with the IEC 61869 standard; they also come with LEM's five-year warranty.
