Co to jest?

A transducer is a device that converts on e form of energy into anothr. In thee contect of electrical power systems, transducers typically convert physical parameters - such as electrical controlt, voltage, mechanical displacement, temperatur, or pressure - into a standardized electrical output, often a low- voltage signal or a digital data stration. This conversion allows control systems, data loggers, and human operators to interpret and act pon realters.

Te cre principler behind a transducer is its ability to sense a change and produce a dimental output. For example, a current transformer (CT) reductes high primary currents ts to a manageable secondary currents that can be measured by by a meter. Moscarly, a voltage transformer (PT) steps down high voltage levels.
