4.- OPERATION
The
line-CVM-D32
device is a power analyser for all four quadrants (consumption and generation).
The device can operate under three different measurement conventions:
Measurement convention
CIRCUTOR
.
Measurement convention
IEC
.
Measurement convention
IEEE
.
The measurement convention is configured using the configuration menu,
