2.2 Implementation Scenarios
A possible implementation scenario is shown in Figure 2.This is a permanent configuration used for
continuous monitoring of power lines using LIQ-60s, LIQ-Gateways and LineMan communications
software.

configuration.
2.3 System Functionality
With regards to communication among the components in the LineIQ family, the LIQ-60s and the LIQ-
Gateway (and, if present, a laptop PC using an LIQ-LocalLink), form a local area network, the LIQ-LAN.
This network’s communication is based on low power RF.
The LIQ-Gateways which communicate with remote control rooms or SCADA systems, can be viewed
as a wide area network, using any of a range of protocols, such as DNP3, IEC 61850 or Web services.
2.4 LIQ-60 Conductor Mounted Sensor overview
The LIQ-60 Conductor Mounted Sensor is a programmable Medium and High Voltage (MV/HV) power
grid logger used to detect and log fault conditions, and to record load information, voltage and conductor
and ambient temperatures on power distribution n e t w o r k s .
Figure 2 shows the LIQ-60 Conductor Mounted Sensor.
