Electrical Failure Investigation & Power Forensics Services

EA Technology provides specialist electrical failure investigation, forensic engineering, and root cause analysis services for utilities, infrastructure operators, manufacturers, insurers, and asset owners across Australia. Our independent Power Forensics™ service helps organisations identify why electrical assets fail, reduce repeat incidents, and improve long-term asset reliability.

Using advanced laboratory testing, forensic diagnostics, materials analysis, and engineering expertise, we investigate failures involving:

transformers
switchgear
cables
overhead line components
insulation systems
high-voltage electrical assets

Our team is widely recognised for its technical independence, investigative expertise, and high-quality forensic reporting.

What Is Electrical Failure Investigation?

Electrical failure investigation is the process of identifying the root cause of failures in electrical assets, components, and infrastructure. Through forensic engineering, laboratory analysis, materials testing, and condition assessment techniques, electrical failure investigations help organisations determine why failures occurred and how similar incidents can be prevented in the future.

Modern forensic engineering investigations are increasingly important for utilities and asset owners seeking to improve network reliability, reduce operational risk, support insurance investigations, and optimise maintenance strategies.

EA Technology’s Power Forensics™ service supports investigations involving:

electrical asset failures
insulation breakdown
thermal damage
material degradation
electrical arc damage
partial discharge-related deterioration
mechanical component failures

Benefits of Electrical Failure Investigation

Validate whether materials and components are fit for purpose
Check that assets are performing as expected
Discover why assets have failed
Identify root causes of electrical equipment failure
Reduce the likelihood of repeat failures and operational disruption
Support condition-based maintenance and asset management strategies
Improve network reliability and operational resilience
Support insurance claims, compliance investigations, and litigation processes

Why Electrical Assets Fail

Electrical asset failures can occur due to a wide range of operational, environmental, electrical, and mechanical factors. Without detailed forensic investigation and root cause analysis, underlying failure mechanisms may remain unidentified, increasing the risk of repeat incidents.

Common causes of electrical asset failure include:

insulation degradation
thermal stress and overheating
electrical arcing and flashover
partial discharge activity
moisture ingress and contamination
corrosion and material degradation
manufacturing defects
poor installation practices
mechanical fatigue and vibration

Understanding the root cause of failure is essential for improving asset reliability, reducing downtime, and supporting informed maintenance and replacement planning.

Types of Electrical Failure Investigations

EA Technology investigates a wide range of electrical asset failures, including:

Transformer failure investigations
Cable failure investigations
Switchgear failure analysis
Insulation failure investigations
Overhead line component failures
Partial discharge-related deterioration
Electrical arc and flashover incidents
Thermal damage and overheating
Material degradation and corrosion analysis
Mechanical component failure analysis

Our forensic engineering specialists use advanced diagnostics and laboratory testing techniques to determine the mechanisms contributing to electrical equipment failure and identify opportunities to reduce future risk.

Root Cause Analysis for Electrical Asset Failures

Effective electrical failure investigation goes beyond identifying visible damage. Root cause analysis combines forensic engineering expertise, operational history, laboratory diagnostics, and materials testing to determine the underlying factors that contributed to failure.

Root cause analysis helps organisations:

prevent repeat failures
improve maintenance strategies
optimise asset replacement planning
strengthen network resilience
improve personnel safety
support insurance and regulatory investigations

By understanding how and why failures occur, asset owners can implement more proactive and data-driven reliability programs.

Laboratory Testing & Materials Analysis

Laboratory testing of the mechanical properties of materials is crucial to determine if they meet the demands of the design. These tests are also useful for assessing whether the true performance of materials lives up to the specifications claimed by manufacturers and to determine the effects of service.

Laboratory diagnostics and materials testing play a critical role in electrical failure investigation by helping engineers identify degradation mechanisms, confirm failure modes, and validate forensic findings.

Mechanical Testing Capabilities

EA Technology can offer a range of mechanical tests, including:

Tensile tests
Compression tests
Hardness tests (Vickers Hardness testing)
Material degradation analysis
Failure surface examination
Mechanical performance assessment of electrical components

Tensile Testing

A graph of force versus displacement is generated, enabling engineers to determine:

maximum tensile strength
elasticity
deformation behaviour
fracture characteristics

Tensile testing can also be used to determine the mechanical strength of specific electrical components such as:

cap and pin insulators
overhead line fittings
structural support components

Compression Testing

Compression tests operate similarly by applying compressive force to a material sample until deformation or failure occurs.

These tests help determine:

optimum load capacity
maximum compression strength
spring stiffness
structural performance characteristics

Compression testing can support forensic investigations involving mechanical failure, deformation, and operational overload conditions.

Vickers Hardness Testing

The Vickers hardness test determines the ability of a material to resist plastic deformation.

A material sample is placed beneath a diamond-tip indenter with a known applied force. The hardness value is then calculated from:

the applied load
the surface area of the resulting indentation

Hardness testing can help identify material degradation, manufacturing inconsistencies, excessive wear, and heat-related changes that may contribute to electrical equipment failure.

Industry Standards & Forensic Methodologies

EA Technology’s forensic engineering methodologies are supported by internationally recognised laboratory testing procedures and engineering standards to ensure technically robust and independent investigation outcomes.

Our investigations may incorporate:

materials testing standards
forensic engineering methodologies
electrical condition assessment techniques
asset reliability analysis frameworks

Combining forensic engineering expertise with advanced diagnostics allows EA Technology to deliver reliable and evidence-based electrical failure investigations for critical infrastructure assets.
