Condition Monitoring

Provider of condition monitoring services, offering a comprehensive range of solutions to all industries.

A condition based maintenance program allows for the efficient use of site resources and offers significant financial benefits.

Motor testing

The use of a combination of proven and reliable condition monitoring techniques enables the motor or generator owner to confidently move from a time based maintenance regime to a condition based maintenance regime. A condition based maintenance program allows for the efficient use of site resources and offers significant financial benefits.

No single test can identify all potential fault mechanisms. Which is why we utilise the following tests to determine the condition of electrical rotating assets and to identify potential failure mechanisms:

• Symmetry – Resistance / Inductance
• Insulation Resistance
• DC Hipot – Step Voltage
• Polarisation Index
• On-line and Off-line Partial Discharge
• Dielectric Dissipation Factor
• AC and DC Voltage Drop
• Current Spectrum Analysis
• Instantaneous Power Analysis
• Current In-rush
• Capacitance

Thermal imaging

With increasing demand to cut costs and remain competitive, many companies are expanding their maintenance programs to include predictive and proactive technologies such as infrared thermography.

We offer thermography services carried out by qualified electricians with Level 2 or Level 1 certification.

Detailed full colour reports detailing IR and visual images, fault severity, fault description and recommendations are issued for every survey. These reports are utilised by maintenance personnel to action identified problems and by insurance companies for compliance audits.

Infrared scans are the fastest way to identify heat generating faults not visible to the human eye.

Common uses for this technology include identification of problems in:

• Electrical assets such as switchboards, cables and motors
• Rotating component failures in gearbox assemblies and conveyors
• Furnace and heat plant inefficiencies due to failing refractory / insulation
• Production problems such as blockages and incorrect levels

Ultrasonic testing

With concerns regarding access and arc flash exposure, thermal imaging is becoming increasingly difficult on some high voltage installations. Ultrasonics coupled with TEV measurements allows for non intrusive assessment of high voltage installations in a safe and accurate manner prior to an in service failure.

All high voltage assets will have some level of partial discharge occurring either internally or on the surface of the insulation. TEV readings taken, can be quantified to determine the severity of any internal discharge problems and any required investigations or maintenance strategies.

We offer electrical ultrasonic and TEV (transient earth voltage) measurement for identification of potentially dangerous and costly conditions in high voltage systems.

Ultrasonic inspection of the assets allows for easy identification of surface tracking that may lead to erosion of insulation and the deposit of potentially conductive surface contamination.

Ultrasonic and TEV detection have become the technology of choice for safe unobtrusive High Voltage electrical inspections.

Typical applications include:

• Transmission and distribution lines
• Substation inspections / audits
• Switchgear
• Transformers
