Primary voltage/Secondary voltage must not exceed the value 9999.
(2)
Primary voltage * Primary current must not exceed the value 60MW.
(3)
It has 2 decimals.
(4)
The secondary voltage has 1 decimal.
(5)
The voltage ratio is the ratio between the primary and secondary voltage.
Note: The 14 registers must be written at once (as a group), otherwise it will respond with an
error.
