Self test Self diagnostics
Start Start of a protective function (instantaneous)
Trip Initiation of a protective function (timed)
Operating time The start and tripping time are determined by varying the input value
instantaneously (stepwise) from a set standby value to a set tripping
value.
Reset time Time required for the relay to reset, in specied conditions following
a trip, so that the successive tripping time does not differ by more
than a set percentage from the previously measured time.The reset
time is determined by changing the tripping reference value to the
reset reference value.
Overshoot time The overshoot time is determined by changing the input value instan-
taneously from the standby value to the tripping value and returning
it, again instantaneously, to the standby value. The difference be-
tween the tripping time of the test device (determined as above) and
the minimum length of the pulse which trips it is the overshoot time.
Reset ratio The ratio between the release value and the value of the same pa-
rameter that operates the device, in specied conditions. The reset
ratio may be less than or greater that 1, depending on whether the
device is an over or under voltage/current relay.

Preface
SME2-IS fault detectors are conforming with ENEL specication GSTP011 (Protection and control
device for MV substation – RGDM control unit); they are installed in remote controlled substations
to detect phase faults and ground faults on both isolated neutral grids and compensated neutral
grids, without the need for modication to handle switching between the two grid congurations and
independently of the power direction;
In particular:
• they detect multi-phase faults and single-phase ground faults,
• they detect line undervoltage,
• they measure the voltage and the active and reactive power of the MV line,
• the open and close the DY800 in response to faults or when remotely operated by UP,
• they interface with the generators on the MV grid to coordinate the regulation of the voltage along
the line and remote disconnection signals.
The input circuits are suited to acquire measurements with integrated phase current/voltage sen-
sors; the device is able, with SW selection, to acquire the current values from active sensors (signal
proportional to the current transduced by the sensor) or passive sensors (DJ 5400 and GSTC005 -
signal proportional to the value of the time derivative of the current), and can measure current and
voltage values with IEC 61869-10 and IEC 61869-11 low power sensors.
The homopolar values are calculated vectorially from the measured phase currents and voltages.
Voltage measurement inputs are available with capacitive voltage dividers.
Two Ethernet communications ports are available, of which one runs the IEC61850 protocol.
To ensure full compatibility with any RTUs already on the secondary systems, the SME2-IS device
is equipped with a dual interface to dialogue with both the UP (DX1215) and future communications
equipment.
The system can be calibrated, programmed and its logs and values read with a PC, or via the Ether-
net communications port using the freely available ThySetter software; all the above operations are
also available via the front panel keypad (MMI).
