Unit configuration
3.3. Programming of LEDs
Through console, it is carried out in the screen “LEDs
programming”.
By keyboard/display:
PROG. TABLE 0 - PROG.CONFIG–PROG. LEDs.
The proceedings are totally analogous to the programming
of digital outputs, except that the activation time is not
programmed and that the possible types are “memorized”
and “non memorized”. The non memorized turns o
when the cause for turning on disappears; to turn o the
memorized a “fault acknowledgement” must be done either
by keyboard/display, digital input or command.
3.4. Programming of general settings
3.4.1. General description
Relay in service: it has to be at Yes in order to have the
protection fully operative. If it is at NO the protection
responds to the communications and the keyboard/
display in order to be put in service; besides it activates the
relay and/or LED programmed as “relay out of service”, by
deactivating all the rest.
Breaker number: it is an identifying text. It can be
programmed as alphanumerical by communications, but
by keyboard only as numerical.
Event mask: in the “events report” section a list is given
with the ones related to the protection. Most of them can
be masked, from the PC. They can not be masked from the
keyboard.
To register an event type the mask has to be set to “NO”.
Transformation ratios: used by the protection only to give
measurements referred to the primary.
Nominal voltage: it is the nominal single-phase voltage. It is
used by the protection to give measurements in PROCOME
format (the scale range of the voltage measurements is 1.2
times the nominal voltage).
Type of voltage: it indicates if the voltage signals connected
to the unit are “simple” (phase-earth) or “compound” (phase-
phase). In the case of units with closed terminals only the
single ones can be applied.
Voltage measurement: it indicates over which voltages
the voltage protections must be applied.
These settings are located in the console on the screen
“general settings and remote port conguration”, and in the
keyboard/display on “PROG.TABLE 0”–“GENERALS” (through
keyboard, the settings of voltage type and measurement
are both under the title “voltage input”).
On the same console screen, and by keyboard/display on
FACTOR CORRECTION (at the same level as PROG.CHART 0)
can be found the following settings:
“Constant active energy (kWh)”: the number programmed
here is the impulse factor of active energy; this means the
kWh number for which the counter is increased in one unit.
“Constant reactive energy (kWARh)”: the number
programmed here is the impulse factor of reactive energy;
this means the kVARh number for which the counter is
increased in one unit.
“Power correction factor”: is a correction factor of the scale
range for measurements of active and reactive power given
to control (it does not aect to data given by display). It is,
in per unit values, the scale range in which measurements
are given related to the corresponding power to 1.2 I
r
and 1.2 V
r
. It means that if the range required is “POWER
BACKGROUND”, the power correction factor is:
POWER SCALE =
“POWER BACKGROUND”
3 * 1.2 I
r
* 1.2 V
r
Example 1. I
r
=5A, V
r
=63.5V (110/√3V)
If it is required that the power full scale should be the power
corresponding to 6 A (1.2 * 5 V) and 76.2 V (1.2 * 63.5)
Power full scale = 3 * 6 * 76.2
Power scale =1
Example 2.I
r
=5 A, V
r
=63.5V (110/√3V)
It is required a power full scale of 1000 W
Power full scale = 1,000
Power scale = 1,000/(3 * 1.2 *5 *1.2 * 63.5) = 0.729
