Transducer Testing
In power systems, electrical measuring transducers are still applied for different purposes. Because of cyber security issues, digital technology may not be able to replace classical transducers in the future. Transducers record electrical parameters such as voltage, current, frequency, phase angle, etc. and convert them into an analog output signal (for example, 0-10 V DC or 4-20 mA DC).
Switching operations or demands for additional power capacity via control centers are based on these measurements.
In order to guarantee their measurement accuracy, periodical calibration of the measuring transducers distributed in nodes all over the power system is of extreme importance.
“Even at small amplitudes we can obtain highly accurate testing signals – this is really impressive.”
