1 Safety
If you do not understand any instructions in this manual, please ask someone to assist you.
For safety reasons, use only GridSense accessories specifically designed for use with these
products, or accessories that have been approved by GridSense. The use of any other
manufacturer's equipment is NOT recommended, will void the warranty and may cause
safety hazards.
The LIQ-60 Conductor Mounted Sensors are intended to be used on high voltage energized conductors
or equipment. Personnel using equipment on energized lines must be authorized by the relevant
regulatory bodies to carry out such work and must have appropriate training.
The information given in this document is given as a guide only. It is the user's responsibility to ensure
that correct and safe procedures are followed at the actual worksite. GridSense offers no warranty or
indemnity for accidents that may occur when following these instructions.
If the LineIQ products and accessories and associated equipment are used in a manner
other than that specified in this manual, the protection provided by the equipment may be
impaired.
1.1 Hazard Assessment
Prior to installing the equipment, the operator must carry out a worksite, pre-job hazard assessment to
identify the safety and environmental needs. This must be done prior to commencing work and prior to
recommencing work after leaving and returning to the worksite. As a minimum, this hazard assessment
should:
• Identify possible hazards and risks
• Identify the safety needs of the job
• Identify the correct procedures, practices and equipment
• Eliminate unsafe conditions and actions from the worksite
• Identify the need for personal protective equipment
• Inspect equipment before use.
Prior to using an LIQ-Gateway, you should check the following:
• The sheaths of all cables are secured and undamaged
• Plugs and connectors are properly connected and serviceable.
• There should also be an ongoing risk assessment during the job.
1.2 Working on energized conductors and equipment
For the correct and safe use of this equipment, it is essential that all operating personnel follow
appropriate safety procedures. Check your employer or relevant regulatory body's rules for working with
energized equipment.

1.3 Equipment safety
The LIQ-Gateway and associated equipment should be maintained and regularly tested to make sure the
equipment is in good order.

2 Introduction to the LineIQ device family
The LineIQ monitoring system allows electricity utilities and other operators of high and medium voltage
overhead conductor distribution and transmission lines to monitor and respond to faults and loadchanges
on the supply grid. The monitoring system consists of Conductor Mounted Sensors (CMS),data
collators, and remote or on-site PC-based aalysis and control software. The LineIQ system links toexisting
SCADA or Distribution Management systems. The CMS communicate with the data collators (LIQ-
Gateways) using short range radio. The LIQ-Gateway and CMS can also communicate with on-site PCs
(e.g. laptop) using short range radio, when an LIQ-LocalLink is connected to the PC. The LIQ-
Gateways in turn communicate with control rooms via a cellular modem or long range radio links, and
can use a variety of different communication standards.
Figure 1 shows a typical implementation of LineIQ monitoring equipment.
The LIQ-60 CMS detect and store network events and also monitor load currents, power factor, conductor
voltage, and ambient and conductor temperatures.
Events such as faults, momentary interruptions, sustained interruptions and restorations are radioed to
the LIQ-Gateway as unsolicited events, which in turn are sent on to the SCADA and control center.
Ongoing measurements such as load currents, conductor voltage, and ambient and conductor
temperatures are periodically downloaded to the LIQ-Gateway, which collates the information and sends
it to the control center.
The LIQ-60s are installed on energized lines. They are battery and solar powered for long-term continuous
monitoring. They can be configured and have their firmware upgraded wirelessly using thesame license-
free short-range radio link (RF link) which is used to download data. Hence, there is no need to remove
the LIQ-60s from the conductors after they have been installed.
LIQ-Gateways function as Remote Terminal Units (RTUs) and are mains powered or battery/solar powered,
depending on location and supply availability. Transmission of load log data from the LIQ-60to the LIQ-
Gateway occurs during a status check which is periodically initiated by the LIQ-Gateway. Thisdata is then
transmitted by the LIQ-Gateway to the remote monitoring system (e.g. SCADA) or is accessed on demand
using LineMan or SCADA via a variety of supported protocols, for example DNP3, IEC 61850 or Web
services.

2.1 Glossary
Term
Meaning
CMS
Conductor Mounted Sensor which detects events on a conductor and logs voltage, current
and temperature for periodic downloading. The LIQ-60 is a CMS.
Commission
Putting equipment into use for the first time. Follows after configuration.
Configure
The process of setting up equipment to perform a designated task. In this manual refers
mainly to firmware. Follows after set-up.
DPF
Displacement Power Factor. A measure of the phase difference between the voltage and
current. { DPF=cos(φ) } Ideally φshould be 0 degrees, so DPF = 1.
DTS
Date & Time Stamping
Event
Profile
Recording
Period
The time (e.g. 1 minute) after an event has been detected and during which the LT-60 records
current and power profiles.
Fast Filter
A 5 sec. average value filter, applies to both current (I) and voltage (V).
FP
Fault Path: a high current event
HV
High Voltage
IED
Intelligent Electronic Device
LED
Light Emitting Diode
LI
Long Interruption: a loss of power on a conductor for at least one minute.
LIQ-
Gateway
The Pole Attached Collator, which receives and collates data from CMS
LIQ-LAN
A local area network consisting of a PC (Laptop) with LIQ-LocalLink for communications, an
LIQ-Gateway & its associated LIQ-60.
