Analog 2IB channel.
Analog 3IC channel.
Analog 4IG channel.
Analog 5ISG channel.
Analog 6 VA or VAB channel, depending on the selected configuration (Wye or Delta at “setpoints>System
Setup>General setpoints>Phase VT Connection”).
Analog 7VB or VBC channel, depending on the selected configuration (Wye or Delta at “setpoints>System
Setup>General setpoints>Phase VT Connection”).
Analog 8VC or VCA channel, depending on the selected configuration (Wye or Delta at “setpoints>System
Setup>General setpoints>Phase VT Connection”).
Analog 9VN or VX channel, depending on the selected configuration (zero sequence measured, or busbar voltage at
“setpoints>System Setup>General setpoints>Auxiliary Voltage”).
The 16 digital channels and the oscillography trigger signal are programmable using 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. Then, this output must be associated to the
digital channel. The oscillography trigger signal can be a single status or a configured logic. The relay default configuration
associates this signal to Virtual Output 83, which corresponds to the logic associated to the general trip of protection
elements.
5.2.4.2 OSCILLOGRAPHY SETPOINTS
These setpoints (“Setpoint > Product Setup > Oscillography”) are described in Table 5–10:
Table 5–10: OSCILLOGRAPHY SETPOINTS
Function Permission (Function): Enabling this setpoint allows to create an oscillography record when the “TRIGGER
OSCILLO” signal is activated.
Trigger Position: This setpoint defines the prefault data (in percentage) stored every time a new oscillo is produced.
Samples/Cycle: This setpoint defines the number of samples per cycle stored in each oscillography record. Please see
example below.
Maximum Number of Oscillos (Max. Number Osc.): 1 to 20 oscillography records can be selected. The capacity of each
record will depend on the capacity = 1Mbyte / Max. Number Osc. This capacity is divided in 9 measures * 4 bytes/measure
+ 2 digital bytes = 38 bytes per stored sample. Please refer to example below.
Automatic Overwrite: This setpoint allows chained oscillographies during the fault (TRIGGER OSCILLO signal
activation). The maximum allowed value to be stored as a chained oscillography is 1 Mbyte. In this case, even if the trip
continues during a time longer than the associated to 1 Mbyte of memory, the relay will stop storing oscillography in RAM
memory until the complete record has been saved in non-volatile memory. The oscillography module will be reset once the
Mbyte has been completely stored in Flash memory and the TRIGGER OSCILLO state is deactivated.
