5.2.2.- Voltage Transformer Secondary
We can now set the value of the secondary of the voltage transformer. Only
three digits are available:
SET U
S
- - -
The procedure is the same one done at the previous sections with the "
max
",
"
min
" and "
display
" keys.
If the CVM-BDM is directly connected to the mains (without voltage
transformer) the values of primary and secondary must be the same, for instance
000001/001.
5.3.- Current Transformer Primary
"SET A P" and five digits appear on screen allowing us to set the primary of
the current transformer. The current green leds light on to avoid mistakes.
SET A
P - -
- - -
The procedure is the same one done at the previous sections with the "
max
",
"
min
" and "
display
" keys.
NOTES:
-
The secondary of the current transformers is not programmable. It is
automatically set at 5 A (... / 5 A ac)
-
The primary current value to be set is also limited by the following condition:
The maximum allowable primary current value which can be set is defined
by the fact that the multiplication of the primary voltage value by this
primary current value cannot exceed 20,000,000.
