Recloser Contact Wear Curve and Settings
Fault Locator
The SEL-351R Falcon provides an accurate estimate of
fault location even during periods of substantial load
flow. The fault locator uses fault type, replica line imped-
ance settings, and fault conditions to develop an estimate
of fault location without communications channels, spe-
cial instrument transformers, or prefault information.
This feature contributes to efficient dispatch of line
crews and fast restoration of service. The fault locator
requires three-phase voltage inputs.
Automation
Flexible Control Logic
and Integration
The SEL-351R Falcon has three independently operated
serial ports: two EIA-232 ports and one optional
EIA-485 port on the side. The recloser control does not
require special communications software. Use any
system that emulates a standard terminal system.
Establish communication by connecting computers,
modems, protocol converters, printers, the SEL-3530
RTAC, an SEL-2032, SEL-2030 or SEL-2020
Communications Processor, SCADA serial port, and/or
RTU for local or remote communication.
Apply an SEL-2032 as the hub of a star network, with a
point-to-point fiber or copper connection between the
hub and the SEL-351R Falcon, as in Figure 5. The
SEL-2032 supports external communications links,
including the public switched telephone network for
engineering access to dial-out alerts and private line
connections of the SCADA system.

Example Communication System
SEL manufactures a variety of standard cables for
connecting this and other IEDs to a variety of external
devices. Consult your SEL representative for more
information on cable availability.
