MONITORING AND CONTROL

8.1 Measurements

Three-phase currents (I-A, I-B and I-C), neutral current (I-N), zero sequence current (3I0)*, positive
sequence current (I-1)*, negative sequence current (I-2)*, negative/positive sequence current relation
(I2/I1)*, maximum current (Imax), second harmonic of each phase (I-A2H, I-B2H and I-C2H), total
harmonic distortion (THD-A, THD-B, THD-C) and thermal image (TI) are given as fundamental values
(DFT).

The accuracy of the phases and neutral measurements in SILA is ±2% in a band of ± 20% the nominal
current and ±4% or ±5 mA (greater of both) in the rest of the band.

In case of the second harmonics currents the relay shows the measurements in amperes (although the
function is set in percentage).

8.2 Alarms Panel

Once the alarms are activated according to their configurations, they can be all recognized at the same
time by holding RESET key from the Alarms Panel main screen.

Accessing to the Alarms Panel, the alarms can be recognized one by one.

Depending on the configuration, after the recognition action, the alarms can be still activated, or they
can be deactivated. In alarms panel menu, these features will be shown. Considering this behavior, the
possibilities for the alarms are:

ALARMS STATE

ALARM PANEL

(*) Once one alarm is deactivated and recognized, it will disappear from the Alarms Panel.

NOTE: If any LED/Alarm has a SRFF or a RSFF configured with the Reset Key as Reset reason, when
pressing Reset from standby screen

, the LED’s will be reset. However,

to recognize the alarms we shall

do it from alarms panel menu.
