As well as the 6 keys to navigate the menus, there are also special keys:
•
Reset. To reset the signals and events.
•
79 lock. This locks and unlocks the recloser.
•
Circuit breaker I/O. This serves to control the circuit breaker.
The SIL-D is fitted with 8 front leds, all of them configurable by the user.
It can storage up to 200 events, allowing any registered incidents to be analysed.
To facilitate problem solving, and as a wide range of fault events may arise (recloser and reverse
criteria) that may not be entirely detected by the oscillography as this is time limited, and as
event recording consists on more general information, with the possibility of fault specific
information being lost, the equipment includes a fault report record. This report allows the last 20
faults to be recorded with a capacity of 24 events per fault.
In order to facilitate the analysis of events, it is fitted with oscillography records. SIL-D is fitted
with 5 oscillographic registers, each one with 100 cycles (2 seconds at 50 Hz, 1.666 seconds at
60 Hz). 3 prefault cycles and 97 postfault cycles. The oscillography start can be configured by
the user. Each oscillography record shows the phase and neutral currents and up to 48 digital
channels, which include start-ups and trips, the protection functions, inputs, outputs, etc. The
COMTRADE format is used (IEEE C37.111-1991).
Current measurements are performed using RMS values, with an accuracy of 2% over a range
of ±20% over the nominal current and 4% over the rest of the range. Standard 5 A and 1 A
current transformers (CTs) are used.
The current measurement of Phase B is calculated and requires of a minimum current of 0.25xIn
of the other phases to be measured.
The voltage measurement is performed using RMS values, with an accuracy of 2%.
It has two communications ports: one front port (RS232) and one rear port. 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 communication ports are designed for different functions. While one is used for control,
principally including the alarm and control functions, the other is designed for specific protection
personnel consultations, with the possibility of consulting and changing, adjustment, or
downloading of events and oscillography, all without affecting the control part operation.
Depending on model, there are the following options respect to rear ports:
1. One RS485 port with selectable communication protocols (selectable by settings)
between IEC60870-103 and Modbus RTU.
2. One RJ45 with IEC61850, DNP3.0 or IEC60870-104 depending on model.
Setting-up a session allows four levels of access to be set up with passwords that can be
configured by the user through SICom communication software.
The protective functions provided, easy-to-use interface, low amount of maintenance and simple
integration make the SIL-D a precise and practical solution for protecting both industrial and
public electrical grids and transformation and distribution centres. The SIL-D protection against
earthing faults is sensitive enough to be used on electric systems with low earthing fault currents.
It can be adjusted to 0.1 times the rated current and extremely low rated levels can be selected.
The main features of the equipment are listed below, and these features will be explained in the
rest of the manual:
