Flexible sensor for detecting AC power, [Weikewei], installation saves 30%

One of the challenges that installers face when monitoring current or power is placing current transformers or other inductive devices on existing conductors. The space inside any switchgear or control panel is always precious, and the size and shape of the conductor must be known before selecting any sensor.

It is much more difficult when the conductor is a large wire or busbar and the time allowed for the system to be powered off is limited. Large wires are bent and shaped to fit the original installation, typically using specialized tools designed for this purpose. Attempting to pass 500 MCM copper wire through the induction loop is very difficult and time-consuming. Adding current detection function to distribution points composed of busbars will force installation personnel to use expensive and low precision split core current transformers, or to find splice plates in busbar components that can be inserted with standard CTs.

Now, a simple and easy-to-use method can monitor AC currents up to 2000 amperes

Flexible cable current sensors only require a small space to wrap around conductors. The cable is connected to a signal conditioner several feet away from the conductor and generates an industry standard 4 to 20 mA signal proportional to the AC current. With a range of 0-500 to 0-2000 amperes and a frequency of 400 Hz, it is highly suitable for a wide range of applications.

Only two wires are needed to provide power and output signals, so current detection is not much easier than this!
