7.6. Protection status
7.6.1. By keyboard/display
It can be seen:
1. Date and time of the relay
2. Status of each of the digital inputs: Open (A) or closed (C)
7.6.2. Through PC (protections console)
On the "status" screens, apart from the measurements
already mentioned, it is possible to see:
1. On the screen 1
a. Date and time of the relay
b. Active table
2. On the screen 2
a. Protection units picked up at the present moment
b. Protection units tripped at the present moment
3. On the screen 3
a. Units tripped on the last trip
b. Command orders
c. Circuit breaker supervision status
d. Closing and trip circuit supervision status
7.7. Oscillograph data recorder
It has a capacity of 1200 cycles, being programmable the
number of cycles per perturbation, so, if, for example, 40
cycles/register are registered, there is space for 30 registers.
If 120 cycles/register is registered there is space for 10,
etc. The number of cycles previous to the pick up is also
programmable between 1 and 100. On each record there
are up to 9 analogical channels registered and up to 32
digital channels which can be chosen from a list selected
from the available signals.
Each record can be started by a rising slope of each of the
digital signals considered by the protection model.
The analogical channels are sent to the console multiplied
by the transformation ratio so that they appear on primary
values. The number of samples per analogical channel cycle
is 32.
