Oscillography
The SIL-V relay stores 5 oscillographic records, with a resolution of 16 samples/cycle and
a size of 88 cycles. The first three of these cycles correspond to pre-fault.
The oscillography is downloaded by communications through the front or rear port using
the Modbus protocol (the protocol is documented in this manual). The SICom
communications program allows the oscillograph to be downloaded and saved in
COMTRADE format (IEEE C37.111-1991).
The following information is included in each oscillographic record:
Number
Analog channels
1
Phase A voltage
2
Phase B voltage
3
Phase C voltage
4
Neutral voltage or bar voltage (depending on model)
This voltage is already in volts.
As well as the analogue magnitudes, the relay saves 64 digital records, with the same
precision as 16 cycle samples. These 64 bits shall contain the following:
