Entube TE Three Phase Voltage Sensor The Entube-TE series is designed for high quality three-phase measurements in a very compact form factor without need for power supplies. This series covers the ranges of ±100V, ±200V, ±300V, ±400V, ±500V, ±750V and ±1000V, with up to 85kHz bandwidth and 0.2% accuracy. The Entube-TE sensor operates as a differential divider network with an anti-aliasing filter on its output. It generates a ±5V or ±10V scaled down version of the line-to-line and line-to-ground voltage on its input terminals. Depending on the software configuration, the sensor outputs phase-to-phase voltages for Delta configuration, or phase-to-ground for Wye configurations. This signal can then be processed by most computer based measurement platforms. One Entube-TE replaces 3 sensors, and only requires one cable for all three signals. This allows for very high channel densities, while delivering high performance for a low cost. Integrated sensor noise (Referenced to input) Gain (Using 10V standard output voltage) Input Impedance The Entube-TE is a differential voltage down-converter designed for 3-phase systems. It outputs all line-to-line and line-to-ground signal pairs. Delta or Wye measurements can be made depending on the input configuration of the digitizer being used (NRSE or Differential).

The Entube-TE can be mounted anywhere between the signal source and the data acquisition system. A female-screw on the low voltage side of the sensor allows for DIN rail mounting, and serves as a safety ground. A standard Ethernet cable is used to carry the conditioned signals from the sensor. The orange, brown and blue pairs carry phase voltages; the green connects to ground and DAQ reference. To avoid limiting the signal bandwidth and to eliminate cross-talk between pairs, a shielded STP Ethernet cable with a maximum length of 100m (330’) should be used. This will keep good reso
