SGC
1 INTRODUCTION
he SGC is an electronic controller for automatization of medium voltage switchgear providing multiple
control and protection functions.
here are three main models for the SGC:
•SGC180: Control functions.
◦Control of one circuit breaker with operation verification, kA2 counter, logging of external
signals, register of events,....
◦Passing fault detection, voltage detection, open phase detection and sectionaliser
automatism.
◦Remote measurement of phasorial voltage, current and power.
•SGC1 5: SGC180 with an integrated multiprotocol R U in small form factor. It's an ideal solution
for space constrained remote control applications, such as overhead line circuit breakers.
For switchgear manufacturers, the SGC is ready to be integrated with in switchgear itself, given its small
size and short depth. his kind of installation is usually the most economical, as the field installation is
simplified, no external components are needed and most cabling errors are avoided.
Each model is available for either horizontal or vertical mounting, with frontal, rear or DIN RAIL fixing
options.

SGC
1.2 FUNCTIONS
1.2.1 CONTROL FUNCTIONS
he SGC device has a wide range of control functions to meet any customer requirements.
1.2.1.1 EVENT/FAULT LOG
Every event detected by the SGC is stored in a non-volatile memory.
Up to 100 events are stored, with associated information (depending on event type).
he main types of events stored include:
●Changes on internal state.
●Pickups, trips and resets of the protection functions.
●Changes on every digital input.
●Switchgear commands.
1.2.1.2 CIRCUIT BREAKER SUPERVISION
he correct operation of the circuit breaker is guaranteed by these functions:
●Open/close operation monitoring.
●Maneuver counter.
●∑kA2 counter.
1.2.1.3 TIME SYNCHRONIZATION
ime is synchronized via the communication protocol, ensuring time stamps coherence between primary
and secondary stations.
he SGC also provides an internal real time clock, so timekeeping is accurate even when the power or
communication link is down.
1.2.1.4 SWITCHGEAR CONTROL
Several parameters can be programmed to tailor the needs of the specific medium voltage equipment
(open/close operation time, latch time, etc.)
here are plenty of digital inputs and outputs fully configurable and available to the user for switchgear
monitoring or other equipment such as: breaker position, fuse protection, personal presence, etc...
3EDP 00110E4

1 INTRODUCTION
1.2.2 MEASUREMENT FUNCTIONS
he measurements done by the SGC are readily available for remote reading, whether them are direct
measurements (such as voltage and current) or computed measurements (active/reactive/apparent
power).
here are also some other computed measures available such as average line current, maximum line
current, composite voltage, etc.
1.2.2.1 CAPACITIVE TRANSDUCER CONNECTION
here are sometimes when it is not possible to install a voltage transformer to do medium voltage
measurements due to space or cost constraints.
In these occasions the capacitive connection on the switchgear bushings (commonly used for voltage
presence indication), can be use as a voltage transducer.
here are two main ways in which the SGC can use this capacitive connection:
•Direct mode1: the voltage inputs of the SGC are parallel connected to the preinstalled voltage
indicators. his can be done in a non-intrusive way thanks to the very high input impedance of
the voltage inputs.
•Indirect mode: substituting the preinstalled voltage indicator on the switchgear with an EDP
HVR3A voltage meter.
he HVR3A doubles its function as a voltage indicator (so it can be installed in place of the
current voltage indicator) and as a voltage amplifier, with an analog output ready to be connected
to the SGC with no loss of phase or magnitude information. More on this solution can be found on
chapter 5.
1.2.3 PROTECTION FUNCTIONS
Depending on the model, there can be one or more of these functions:
●Phase and Neutral overcurrent protection 50/51/50N/51(N).
●Phase and Neutral Directional protection (67/67N).
All the data relative to these units is always available through remote communications, being able to be
read from the primary station.
1.2.4 OTHER FUNCTIONS
●Passing fault detection.
●Voltage detection.
●Sectionaliser automatism.
1.2.5 SELF CHECKING
he SGC is constantly performing background control and verification tasks to ensure that its
performance is always within limits.
1 Due to the distortion created by most voltage indicators, this mode is only useful for voltage detection, but
not measurement.

1.2.6 FIRMWARE UPDATES
he SGC is fully field-upgradeable. New firmware/software versions can be deployed via the frontal
maintenance port (please refer to 3.3.1 if you have either SGC180 or SGC185 devices or refer to 4.4.4 if
you have SGC195 devices for a more detailed explanation).
1.2.7 LOCAL OPERATION
Basic SGC is intended for remote operation and there are no direct controls for local operation. hem can
be added optionally.
It is always possible to monitor and configure the unit locally with a computer connected to the frontal
communications port with our software qtAjustes2.
he software functions are:
•Monitor and download of settings files.
•Direct reading of digital inputs/outputs and analog measurements.
•Capacitive transducer field-calibration for its use with a HVR3A meter.
•Simulation of events in order to check the interoperability with the primary station during the
commissioning.
