Business Purpose
Liberty Consulting Services (LCS) was formed in 2006 to provide a complete electrical engineering and
consultancy service in the Australasian region, specialising in the design of high and low voltage electrical
earthing and grounding systems, lightning protection, surge and transient protection solutions, and site
audits and testing services for a diverse range of industries.
The projects worked on have included renewable energy plants utilising solar photovoltaic arrays, wind
turbines and biomass cogeneration, as well as conventional thermal power generation based on coal and
gas. Other industries where we have expertise include mining, oil & gas, water treatment, defence &
aviation, rail & other transport systems, telecommunications & broadcasting, and light industrial/commercial
facilities such as universities, hospitals and high rise buildings.
The company provides design and application advice for power and communications earthing systems in all
of these types of facilities, by combining extensive experience and rigorous diagnostic tools and field testing
methods to identify solutions. LCS engineers offer comprehensive risk - benefit consultancy services, and
the provision of professionally written engineering reports and layout drawings.
All engineering services are completed and supervised by fully qualified professional engineers, with
current CPEng and RPEQ status. Specifically, the services LCS offers include:
Design of high voltage switchyard & substation earthing systems
 Site soil resistivity testing, and computer analysis and design using the industry leading software
package CDEGS by SES Technologies.
 Earthing design to achieve safe step and touch potentials in accordance with the Australian substation
earthing guides - ENA EG-1 (IEEE Std 80), ENA EG-0, and AS/NZS2067.
 High voltage substation and switchyard earth system testing using low current, off-frequency current
injection testing (CIT) methods, with tuned voltmeters to measure step, touch and transfer voltages.
 Earthing and grounding design services for specialised applications, such as large scale solar PV

 Electricity bill assessment (kW, kVA and kVAr) for cost savings under existing and future electricity
tariffs, with recommendations on how to implement savings measures.
 Calculation of savings in greenhouse gas emissions, due to the reduction in kVA demand achieved by
power factor correction.

Forensic engineering services, with site audits & power quality investigations
 Site surveys in the specialised fields of direct strike lightning protection, surge and transient protection,
and earthing solutions for facilities and their occupants.
 Site evaluations of lightning damage effects, identification of equipotential bonding in earth systems and
rectification advice to eliminate dangerous earth loops.
 Investigation of stray currents & voltages, leakage current & fault loop impedance testing, AC & DC
corrosion effects, and identification of parallel earth-neutral return current paths.
 Professional engineering reports, with evaluation of site testing and inspection results, and the provision
of cost-effective solutions.
 LCS engineers work together with the client and contractor to identify hazards and recommend
improvements required to minimize risks presented by lightning and other harmful power disturbances.
Risk assessment and management
LCS personnel have a proven history of working with diversified industry groups to evaluate and provide
recommendations on specific power quality and lightning protection solutions. Through the application of
proven methods, and in conjunction with the recommendations in relevant standards, LCS can offer a
comprehensive solution to all lightning and power quality problems.
With our detailed knowledge, considerable experience and understanding of all relevant codes and
standards in this field, LCS will carry out risk assessments to calculate the probability of loss. Using a
proven, systematic approach, LCS will make recommendations for cost-effective protection measures and
techniques to bring the risk of loss below a "tolerable" level.
Key parameters considered in the risk assessment of a modern facility include:
 Risk of lightning in the region;
 Site specific details such as surrounding terrain and site elevation;
 Type of structure and equipment usage; and
 Strategic importance of the operation to an organization.

Equipment & Resources
LCS uses the industry leading software package – CDEGS – Current Distribution, Electromagnetic Fields,
Grounding and Soil Structure Analysis, to model soil resistivity field test results and perform earth grid
design calculations for high voltage substations, switchyards and power generating plants to effectively
handle fault currents while limiting step, touch and transfer voltages to safe levels.
The software is based upon formulae provided in relevant international standards, including but not limited
to ENA EG-1, IEEE Std 80, BS 7354, and the EA 41-24. The primary advantage of the software used by
LCS is that the developed software algorithms compare well with actual test data.
In addition LCS uses proven design methods and the latest technology equipment applications to provide
lightning protection solutions to these installations.
Depending on the size of the facility
being tested, fit for purpose test
equipment is employed to accurately
measure earth grid resistance, step,
touch and transfer voltages, and
electrical continuity of earthed
structures in high voltage substations,
switch-yards and power plants.
Testing of lightning protection earthing
systems is also performed accurately
using purpose designed and suitably
powered test equipment.

Staff Profile
Grant Croghan is the Director and principal electrical engineer at LCS. Grant
received his Bachelor of Electrical Engineering (with Honours, majoring in
electrical power systems and power electronics) from James Cook University
in Townsville, Australia in 1985, and received a Master in Business
Administration (majoring in International Business and Finance) from Deakin
University in Geelong in 1997.
Grant began his career as an electrical engineer in the Australian military,
after which he worked with one of Australia’s large multinational organisations
- Pacific Dunlop’s Olex Cables division (now Nexans Olex). As a power
systems engineer with Olex, Grant traveled extensively in Australia and Asia,
working on projects involving the installation of high voltage transmission and
distribution systems (including extra high voltage underground cross linked
polyethylene – XLPE - insulated cables).
Grant then spent 10 years working in the electrical industry in Asia, primarily with ERICO (Electrical Railway
Improvement Company, now Pentair) based in Singapore. Grant has worked in sales management and
technical field application roles, and is well versed in electrical power systems, earthing, lightning and surge
protection principles, and their applications for harsh environments.
Over the last decade Grant has been operating his own consulting engineering business, specialising in
providing power quality solutions to the mining, water, oil and gas, building and construction industries. This
role has involved conducting site surveys, and providing professional engineering reports. Grant has
developed his expertise in electrical substation earthing design – in particular the application of design
methods in Australian & International Standards (ENA EG-1, ENA EG-0, AS2067, IEEE80 & IEEE81), as
well as the application of Australian & International Standards for lightning protection (AS1768 and
IEC62305) for industrial and telecommunications applications.
More recent work has focused on power quality improvements for water treatment facilities in South East
Queensland, and earthing design and testing for solar photovoltaic energy farms throughout Queensland
and New South Wales.
Grant is a Member of the Institution of Engineers Australia, a Chartered Professional Engineer (CPEng),
and a Registered Professional Engineer of Queensland (RPEQ). Grant has also completed a Company
Directors’ course, and has been a Member of the Australian Institute of Company Directors. He has
presented technical papers at various Engineering conferences in Australia and Asia.
