Measuring transducers ET/UET 51x
Measuring transducersET 51x are intended for measuring and monitoring single-phase electrical power network. Voltage inputs and current inputs are electrically isolated from the system by means of high resistive input chain and current transformer respectively. It measures true RMS values by means of fast sampling of voltage and current signals, which makes instruments suitable for acquisition of transient events. A built-in microcontroller calculates measurands (voltage, current, frequency, energy, power, power factor, power angles, THD U, THD I, MD) from the measured signals.
Features
- Measurements of instantaneous values of all single phase values; U, I, P, Q, S, f, φ, energy, THD U, THD I, MD
