Oscillography - GE F650 Instruction Manual

5.2 PRODUCT SETUP
5.2.4.1 OVERVIEW
F650 elements allocate 1-Mbyte of memory for storing oscillography records. These oscillography records are stored in
non-volatile memory.
Oscillography records are stored in COMTRADE ASCII - IEEE C37.111-1999 standard format.
The oscillography module is in charge of storing the instantaneous values of the 9 analog signals and the 16 programmable
digital signals at Setpoint > Relay Configuration > Oscillography in fault conditions (OSCILLO TRIGGER signal
activation).
All oscillography records store all analog signals (fixed) plus 16 digital signals (programmable). The order of storage in the
case of analog signals is as follows:
Analog 1 IA channel.
Analog 2 IB channel.
Analog 3 IC channel.
Analog 4 IG channel.
Analog 5 ISG channel.
Analog 6 VA or VAB channel, depending on the selected configuration (Wye or Delta, at "Setpoint>System Setup >
General Settings > Serial VT Connection").
Analog 7 VB or VBC channel, depending on the selected configuration (Wye or Delta, at "Setpoint>System Setup >
General settings > Phase VT Connection").
5
Analog 8 VC or VCA channel, depending on the selected configuration (Wye or Delta, at "Setpoint>System Setup >
General settings>Phase VT Connection").
Analog 9 VN or VX channel, depending on the selected configuration (zero sequence measured, or busbar voltage, at
"Setpoint>System Setup>General settings>Auxiliary Voltage").
The 16 digital channels and the oscillography trigger signal are programmable using the EnerVista 650 Setup software at
Setpoint > Relay configuration > Oscillography. Each digital channel can be associated to a single status or to a logic
status. In this last case, the logic must be configured using the PLC Editor tool, at Setpoint > Logic Configuration inside
EnerVista 650 Setup, and its output must be associated to a virtual output. This virtual output is then associated to a digital
channel. The oscillography trigger signal can be a single status or a configured logic. The relay's default configuration
associates the oscillography trigger to Virtual Output 83, which corresponds to the logic associated to the general trip of
protection elements.
