The cost depends on factors such as:

• Number of distribution boards and equipment to be inspected
• Complexity of the electrical installation
• Site access and operating load conditions

We offer a FREE Thermography Site Assessment to assess your facility and provide an accurate, transparent, site-specific quotation — instead of using generic or inflated day-rate pricing.

Infrared thermography is important in Singapore because it supports electrical safety, helps prevent fire risks, and improves the reliability of critical facilities. Due to Singapore’s warm and humid environment, electrical systems may experience higher heat stress and faster deterioration, making thermal scanning an important part of preventive maintenance.

It helps to:

• Detect hidden early signs of electrical failure quickly
• Pinpoint faulty components more accurately
• Avoid expensive emergency repairs and unexpected downtime
• Support building fire safety, OSHA, EHS, and insurance audit requirements
• Extend the healthy operating lifespan of equipment
• Reduce unnecessary manpower deployment
• Improve preventive maintenance planning
• Increase productivity and support energy savings
• Carry out inspections without shutdown, contact, or disruptio

Infrared inspection, also known as thermal imaging inspection or thermal scanning, is a Non-Destructive Testing (NDT) method used for Condition Monitoring (CM), preventive maintenance (PM), and predictive maintenance (PdM).

It is:

• Performed safely on live equipment without physical contact
• Conducted without the need for shutdowns or operational disruption
• Used to measure surface temperatures with infrared thermal cameras
• Able to detect abnormal heat patterns before equipment failure occurs

Your facility may require an infrared inspection if you experience:

• Frequent electrical tripping, unusual heat, or load imbalance
• Electrical systems that are more than 10 years old
• Critical operations where uptime is important
• Insurance, audit, or compliance requirements
• Preventive maintenance plans focused on reducing risk

The typical inspection duration is:

• Small buildings: 1–2 hours
• Commercial facilities: 2–5 hours
• Industrial plants or data centres: half a day to one full day

The actual time required depends on the number of assets, site access arrangements, and load conditions during inspection.

Before scheduling the inspection, it is useful to prepare:

• Asset list or Single-Line Diagram (SLD)
• Number of distribution boards, risers, UPS units, and transformers
• Details of critical loads or restricted access areas
• Preferred inspection timing, such as normal load or peak load period
• Safe and clear access to electrical panels

Suggested inspection frequency:

• Once a year for commercial or industrial facilities
• Every quarter for high-risk or mission-critical facilities, such as data centres and hospitals
• Before major handover or commissioning works
• According to your preventive maintenance or shutdown schedule

According to Singapore Standards TR119, a Qualified Thermographer should hold at least a Level-2 Infrared Certification and have the relevant technical competence for the assets being inspected.

Only a Qualified Thermographer should carry out the inspection, analyse the findings, and prepare the official thermography report.

You will receive a detailed thermographic report endorsed by LEW, which includes:

• Thermal and visual images
• Temperature readings and severity assessment criteria
• Suspected root-cause analysis
• Recommended corrective actions
• Report delivery within 7 working days
