Voltage Interface Module

The voltage interface module (VIM) enables voltage, power, and energy monitoring for the TeSys island .

The reference number is TPRVM001.

The main functions of the VIM are as follows:

Measure single-phase and three-phase line voltages (47–63 Hz) at one connection point of the TeSys island
Monitor the energy-related data at the island level
Monitor the voltages in single-phase systems L-N or L-L
Monitor the voltages in three-phase systems without neutral N connection
Calculate the RMS phase voltages and the voltage phase sequence
Monitor for fundamental frequency
Identify the level and duration of dip and swell events

Refer to Avatar Wiring Schematics for module wiring.

The VIM is connected upstream to the TeSys island common power supply.

The VIM communicates with the bus coupler, sending operational data.

The connection specifications for measuring input are as follows: removable spring terminal block with three rigid cables sized 0.2–2.5 mm² (AWG 24–14).
