As mentioned in the previous paragraph, 2 oscillographic logs are available, each with a size of 138
cycles (2.7 seconds at 50Hz, 2.3 seconds at 60Hz): 10 pre-fault cycles and 128 post-fault cycles. The
oscillography start can be configured by the user. Each oscillographic record contains the phase and
neutral currents, the phase and neutral voltages and up to 128 digital channels, which include start-ups
and trips of the protection functions, inputs, outputs, etc. The format used is COMTRADE (IEEE
C37.111-1991).
Current measurements are made using r.m.s. values with a precision of 2% in the 20% band around
rated current. The current transformers used at standard 5A and 1A CTs.
It has three communications ports: one front port (RS232) and two rear ports. Optionally RS485, plastic
optical fiber or Ethernet can be chosen for the physical medium of the ports. The RS232 port allows a
PC to be connected and the equipment to be monitored using the SICom program in Windows 7,
Windows 8, Windows 8.1 or Windows 10 (supplied by FANOX).
The rear communications ports are designed for different functions. One is designed for control, mainly
including the alarm and command functions, and the other is designed for specific queries by protection
staff, who may query or change settings or download events and oscillographs without interfering with
the operation of the command side. Respect to rear communications it is offered two possibilities: the
possibility of having two RS485 communication ports, one for MODBUS RTU protocol and the other one
for IEC 60870-5-103 protocol or having two rear ports, one RS485 for MODBUS RTU protocol and the
other one RJ45 (Ethernet) for IEC 61850 or DNP 3.0.
Logging-in allows four levels of access with passcodes that can be configured by the user.
Thanks to the protection functions that are available, its user friendly interface, its reduced maintenance
requirements and simple integration, the SIL-B is an accurate and practical solution for protecting a
feeder system. SIL-B offers protection against earth faults that is sufficiently sensitive for use with
electrical systems with a low earth failure current. It can be adjusted to 0.1 times the rated current and
really low rated levels can be selected.
The main features of the equipment are listed below. These will be described in greater detail in this
manual:
