Real Time Clock (RTC)
For events, oscillographies and alarms the protection equipment required a clock for date and
time stamping. This clock must keep the date and time even with no power supply, for up to 72
hours (With the capacity charged beforehand).
If there is an events queue, and the clock is synchronized with a date and time prior to the last
stored event, the relay does not reorder the queue, but rather it stores the new events after the
events already in the queue.
This clock can be synchronized with another clock in various ways:
•
From the HMI.
In this case the date and time can be entered using a keyboard. The relay will
save a new event indicating that it has been synchronised.
•
By protocol.
There are two options in this case:
o
Local protocol.
The performance is identical to the HMI, the relay synchronises the date
and time and executes a new synchronisation event.
o
Remote protocols.
These protocols can include continuous synchronisation sections.
For this reason, the execution of synchronisation events is inappropriate.

Oscillography
The SIL-B relay stores 2 oscillographic logs, with a resolution of 16 samples/cycle and a size of
138 cycles, of which the first 10 correspond to the pre-fault.
The oscillography can be downloaded by communications from the front or rear port through the
Modbus protocol (the protocol is documented in this manual). The SICom communications
program allows the oscillography to be downloaded and saved in COMTRADE format (IEEE
C37.111-1991).
The following information is included in each oscillographic log:
Number
Analogue channels
1
Phase A current
2
Phase B current
3
Phase C current
4
Neutral current
5
Phase A voltage
6
Phase B voltage
7
Phase C voltage
8
Busbar voltage
The primary current and voltage are expressed in amperes and volts.
As well as the analogue magnitudes, the relay stores 128 digital logs, with the same precision of
16 samples/cycle. These 128 bits have the following content:
