Demand measures
Demand measures are calculated as:
Fixed demand
I
L1FIXH
,
I
L2FIXH
,
I
L3FIXH
.
Every fixed demand period t
FIX
an average magnitude is calculated based on samples taken every 1
second. Update is carried out at the end of the same period. The fixed demand measures may be reset
to zero by means the Reset on demand measures command (ThyVisor Commands menu).
The tFIX parameter (Fixed demand period) is available inside the Set \ Demand measures menu.
Rolling demand
I
L1ROLH
,
I
L2ROLH
,
I
L3ROLH
.
The average magnitude is calculated inside a mobile window of N·T length where:
• N is the user-defined number of cycles and,
• T is the user-defined sub-period.
An average magnitude is calculated based on samples taken every 1 second; update is carried out
at the end of the every sub-period. The rolling demand measures may be reset to zero by means the
Reset on demand measures command (ThyVisor Commands menu).
The tROL (Rolling demand period) and N.Rol (Number of cycles for rolling on demand) parameters are
available inside the Set \ Demand measures menu.
Peak demand
I
L1MAXH
,
I
L2MAXH
,
I
L3MA XH
.
Every sub-period t
ROL
the maximum value of the average magnitude is calculated based on samples
taken every 1 second. Update is carried out at the end of the same period. The peak demand measures
may be reset to zero by means the Reset on demand measures command (ThyVisor Commands menu).
The tROL (Rolling demand period) parameter is the same for rolling demand setting.
Minimum demand
I
L1MINH
,
I
L2MINH
,
I
L3MINH
.
Every sub-period t
ROL
the minimum value of the average magnitude is calculated based on samples
taken every 1 second. Update is carried out at the end of the same period. The peak demand measures
may be reset to zero by means the Reset on demand measures command (ThyVisor Commands menu).
The tROL (Rolling demand period) parameter is the same for rolling demand setting.
Oscillography
Trigger Setup
Following parameters, available inside the Set \ Oscillography \ Trigger Setup menu, are user-pro-
grammable:
• Pre-triggertime and Post-triggertime.
• Elementpickuptrigger; the information recording starts when a state transition on any protec-
tive element occurs if the parameter is set to ON.
• Triggerfromoutputs; the information recording starts when a state transition on the selected
output relay occurs if the parameter is set (K1...K6).
• Binary input trigger; the information recording starts when a state transition on the selected
binary input occurs if the parameter is set to ON.
• Trigger from inputs; the information recording starts when a state transition on the selected
binary input occurs if the parameter is set (IN1...INx).
• 80%Bueralarm; when the 80% of the buffer space is reached an alarm may be issued if the
parameter is set to ON.

Set digital channels
The desired digital quantities may be select inside the Set \ Oscillography \ Set digital channels
menu.
Everyone of twelve digital channel may be associated to one of the selected I/O signal (K1... K6, K7...
K10, IN1, IN2, IN3...IN42
[2]
).
Set digital channels from 87G-M-L
The start and trip states (ST Id>-L1,...TRId>-L1,...,TRId>>-L3 ST SatDet) may be select inside the
Set \ Oscillography \ Set digital channels from 87G-M-L states menu.
Nota 1 The 26 menu is available when the MPT module is enabled
Nota 2 The output relay K7...K10 and binary input IN3...IN42 states is meaningful when the I/O circuits are present (MRI and MID16 modules)
