Before operating
VBO3
for the first time, use the shipping documents to verify that all accessories are
available.
1.2 Designated use
VBO3
is a voltage transformer and used as an accessory for OMICRON's CMC test sets. The device
is intended for use with CMC test sets only.
VBO3
transforms a CMC's output voltages of 0 ... 300 V to
0 ... 600 V.
Therefore, you can use CMC test sets for testing the V>> stage of LOM protection at wind power
stations. Their threshold is at least 460 V (nominal voltage in wind power stations is 690 V L-L
(398.37 V L-E)). You can also test other renewable energy systems such as biogas, photovoltaic,
small hydroelectric power as well as combined heat and power plants.
Furthermore, you can test industrial networks with voltage levels > 300 V.
