SPECIAL FUNCTIONS
The templates described above only generate a suitable configuration for a certain test.
Apart from giving a configuration, the functions also carry out more complicated tests
where the generation or stoppage values vary with time in a totally automated process.
To access the functions:
It has two functions: Recloser and CT Magnetisation.
Recloser.
This function is designed to verify, in a very simple manner, the
correct operation of an integrated RECLOSER; that is, a device
that include the MV circuit breaker, the protection CTs, the protection relay with recloser
function and the total control of the system. These devices are found more and more
frequently in Medium Voltage Distribution circuits.
The results shown include trip time and reclosing time (dead time) of each one of the
reclosing cycles that the device actually carries out.
It does not require any type of configuration by the operator, although he must take into
account that the maximum time this test lasts is set, by default, at 8 seconds. This time
should be sufficient for the majority of the cases, but the operator must decide if it should
be longer or shorter, editing it if required. The function will be left with the last length of
time assigned. If you wish, you can configure the test for it to end by binary input or by
intervention of the operator, instead of by time.
The trip times are represented as T and the reclose times as R.
