If you are to operate your plants as efficiently as possible, then you need constant information about the current status of devices and functions. In wind power installations, for example, this includes the effective current consumption of motors for pitch adjustment, device heaters or brakes, as well as information concerning their utilisation and operating behaviour.
Using the RMS method, our ACT20C-CMT and ACT20C‑CML universal current measuring transducers measure the real power consumption of a connected load for direct and alternating currents – even with distorted curves.
In combination with passive current transformers, the new ACT20C-CML current measuring transducers can also be used for measuring very high AC currents. This way, the measurement range can be extended according to application needs. The data transmitted by the ACT20C current measuring transducers allows you to continuously monitor connected units in terms of whether levels are exceeding or falling below defined load points, as well as allowing you to maintain an overview of the units’ use and service life. This makes it far easier to optimise plants and processes on a targeted basis.
Wind power plants make up one typical area of application for our ACT20C station with current measuring transducers. Here, it is vital that motor or brake overloads or anomalies are identified at an early stage and that operators respond to poor performance in cooling fans or rotor blade de-icing systems in a timely fashion.
