Product Overview
Features
Secure Communication Over
Cellular Network
The SEL-3061 offers comprehensive security methods
that include VPN, IPsec, SPI firewall, and media access
control (MAC) address filtering to ensure the confidenti-
ality and integrity of data communications over a cellular
network. The SEL-3061 uses RADIUS and user account
privileges to grant access to the device.
Device Management
The SEL-3061 simplifies device monitoring and man-
agement via the web interface of the router including
over-the-air settings changes and firmware upgrades.
Ubiquitous Connectivity
The SEL-3061 supports 4G LTE and 3G cellular technol-
ogy and uses cellular networks to provide wireless con-
nectivity for a variety of critical infrastructure devices.
Reporting and Alarms
The SEL-3061 uses the Syslog format to log events. The
router maintains an internal record of as many as 30,000
event logs in nonvolatile memory that can be down-
loaded into a CSV file. The Syslog supports two Syslog
servers. Notifications and alarms can be triggered by the
events and sent by using either SNMP, email, or short

message service (SMS) messages. The SEL-3061 has an
output alarm contact that pulses for major and minor
alarms.
The SEL-3061 supports SNMP to provide state informa-
tion and notifications (traps) for events that indicate the
device health and status. The SEL-3061 allows Manage-
ment Information Base (MIB) files in zip format to be
downloaded to provide information about data and traps
available via SNMP.
Application Examples
The SEL-3061 serves as the communications link for
field devices or backhaul communications device. For
electric utilities, the SEL-3061 provides connectivity to
devices such as recloser controls, motor-operated
switches, capacitor banks, voltage regulators, meters, and
other IEDs. The combination of serial and Ethernet ports
on the SEL-3061, along with secure tunneling, provides
application flexibility and makes installation easy with-
out sacrificing security.
SCADA
The SEL-3061 provides the communications link to
aggregate data from field devices and forwards it to
SCADA systems and HMIs. The SEL-3061 can be used
in data acquisition and slow-to-medium speed control
applications. SCADA includes analog and discrete I/O
monitoring and metering. The SCADA control includes
set-point changes of processes and operations of discrete
I/Os. Field devices connect directly to either the Ethernet
port or serial port on the SEL-3061. The SEL-3061 links

these devices to a SCADA system via cellular WAN con-
nections and allows the SCADA to poll each device by
using DNP3 over TCP/IP and Modbus TCP/IP.
Engineering Access
The SEL-3061 allows users to access IEDs to view and
modify settings and download oscillographic event
reports through VPNs.
Distributed Data Acquisition
Modern automation systems can be distributed over a
large geographical area. These automation systems mon-
itor and process input signals, execute logic, and enable
or disable outputs. In some instances, it is necessary to
perform data acquisition on the status or value of the
connected I/O. A distributed data acquisition system uses
an automation controller as the data concentrator and a
computer as the SCADA host. The system uses remote,
discrete, and analog I/Os. As shown in Figure 3, a single
SEL-3061 at each site both provides the connectivity
between these remote I/Os with the automation control-
ler and backhauls the collected data to the SCADA com-
puter.

Distribution Automation
The SEL-3061 provides cellular connectivity to remotely
monitor and control recloser controls and sectionalizers
for distribution power systems, as shown in Figure 4. In
cases where customers rely on communications schemes
for power restoration, the SEL-3061 provides the con-
nectivity. The main difference between the distribution
automation (DA) systems that use line-of-sight radios
and DA systems that use an SEL-3061 is that the
SEL-3061 and DA can be installed at any IED location
that has cellular coverage. The DA controller polls data
from each recloser control for monitoring and sends con-
trol signals through the WAN and the SEL-3061.
SEL-FLT/SEL-FL R Network Backhaul
The SEL-FLT and SEL-FLR Fault and Load Transmitter
and Receiver System provides wide-area load monitoring
and fault location from line-powered SEL-FLT devices.
The SEL-FLR collects load data and fault information
from the SEL-FLT devices and sends the collected data
to an Operation Management System (OMS) or Energy
Management System (EMS) via a WAN. The SEL-3061
provides the communications link between the OMS and
the SEL-FLR. When connected to the SEL-FLR the
SEL-3061 provides wireless connectivity for the
SEL-FLT/SEL-FLR networks, as illustrated in Figure 5.

Distributed Generation
The SEL-3061 provides the connectivity to remotely
monitor and control relays, devices, and equipment at
distributed generation (DG) sites. In most applications,
an automation controller interfaces with devices located
inside the DG facility. The SEL-3061 can be connected
to the controller to provide backhaul connectivity for
devices located at the DG sites. The SEL-3061 is suitable
for monitoring and non-protection speed control of the
DG site.
Voltage Regulators
Voltage regulators installed outside the substation use the
SEL-3061 to report their status and receive control com-
mands from either a controller or the SCADA system.
Connect the voltage regulator to the SEL-3061 by using
either the serial or Ethernet interface.
Capacitor Bank Controls
The SEL-3061 provides communication for remote mon-
itoring and automated or manual control of capacitor
banks.
Pump Automation Controls
Monitor and control critical infrastructure, such as water
and wastewater pumps, by using the SEL-3061 to pro-
vide remote access to SEL-2411P Pump Automation
Controllers. During both routine operations and natural
disasters, the cellular network provides a reliable path
from a control center to the field. Use an Ethernet switch
to connect more than one controller to a single
SEL-3061.
Network Backhaul
A radio or Advanced Metering Infrastructure (AMI) net-
work usually has an access point that concentrates data
from remote endpoints. The access point is usually con-
nected to a WAN or another wireless network. The
SEL-3061 can be used as the link between the access
point and the WAN or the wireless network by providing
backhaul for these networks.
