SAM600-VT for conventional voltage measurements

IEC18000514 V1 EN-US
Figure 3:
A SAM600-VT module has four analog input measurement channels and interfaces
conventional voltage transformers with a configurable input voltage between 100V – 125V AC
(phase-phase) on the secondary interface. The measurement chain is calibrated and
temperature compensated.
The neutral voltage as provided in the IEC/UCA 61850-9-2LE stream can either be measured or
calculated as sum of the three phase values.
Binary inputs are provided to signal fuse failure and test conditions in the IEC/UCA
61850-9-2LE stream through a corresponding quality bit in order to allow for blocking
conditions in the IEDs receiving the data stream. Three inputs which can be wired to the
secondary contacts of MCBs are pre-assigned to signal a fuse failure per phase. A fourth input
is provided to signal a test condition in the stream. The polarities of the binary inputs are
configurable.
A SAM600-VT module can be configured to provide IEC 61850 access points on each physical
port that is not used for SAM600 system bus connection. An IEC61850 access point can
subscribe or publish IEC/UCA 61850-9-2LE streams.
A SAM600-VT module supports IEEE 1588 access point in a standalone configuration or as an
edge module in a daisy chain system bus.
