Five-star hotels carry a distinctive electrical load pattern — continuous HVAC and chiller plant running around the clock, plus sharp banquet and kitchen demand spikes during events — that stresses LT panel and transformer connections differently than a standard commercial building’s more even, business-hours-only load profile, making transformer-specific thermography (not just panel scanning) a relevant addition to the standard scope.
NFPA 70B applies its temperature-rise threshold to both panel connections and transformer bushings/terminations, and transformer oil temperature indicators provide a secondary cross-check against the thermal imaging finding, with IEEE guidance treating transformer connection hotspots as higher priority than equivalent panel-level findings given the higher replacement cost and lead time if a transformer fails versus a panel component.
In a thermographic survey Elion carried out on LT panels and the transformer for a five-star hotel in Amritsar, Punjab, a loose busbar connection was identified on the transformer’s secondary side, above the NFPA 70B priority threshold. Corrective tightening and torque verification was estimated at under ₹1 lakh, a modest cost against transformer replacement lead time, which for a hotel-scale unit can run several weeks and force temporary generator dependency during banquet season.
For hospitality properties specifically, Elion recommends scheduling the transformer and LT panel thermography scan ahead of the property’s peak banquet/event season rather than on a fixed calendar date, since load-driven thermal stress on connections is highest during exactly the period when an unplanned outage would be most commercially damaging.
Hotels’ round-the-clock HVAC load plus sharp banquet-driven demand spikes stress LT panel and transformer connections differently than standard commercial buildings — scanning ahead of peak banquet/event season, not on a fixed calendar date, catches load-driven risk before it matters most.

Understanding Electrical Thermography
Electrical thermography is a technique that uses thermal imaging cameras to detect abnormal heat patterns in electrical systems. It works on the principle that faulty electrical components generate excess heat, which can be detected and visualized through thermal imaging.
During a thermographic survey, a trained professional uses a thermal imaging camera to scan LT panels and transformers. The camera captures the heat signatures of various components, which are then analyzed for any abnormalities. Hotspots, which indicate potential issues, are identified and documented for further analysis.
Understanding electrical thermography is crucial for conducting a successful survey. It requires knowledge of electrical systems, as well as the ability to interpret thermal images accurately. This ensures that potential issues are not overlooked and appropriate actions can be taken to address them.

Scope of the Survey for a Five Star Hotel in Amritsar, Punjab
Elion recently conducted a thermographic survey for a five-star hotel in Amritsar, Punjab. The scope of the survey included LT panels and transformers throughout the hotel premises. The objective was to identify potential electrical issues and provide recommendations for improving safety and efficiency.
The survey presented several challenges due to the size and complexity of the hotel’s electrical system. The team had to navigate through multiple floors, rooms, and corridors to access the LT panels and transformers. Additionally, the survey had to be conducted during non-peak hours to minimize disruption to hotel operations.
Despite these challenges, Elion’s team successfully completed the survey within the agreed timeframe. They used their expertise and state-of-the-art equipment to capture accurate thermal images and identify potential issues.
Preparing for the Survey: Equipment and Tools
Preparing for a thermographic survey requires the right equipment and tools. The most important tool is a thermal imaging camera, which captures the heat signatures of electrical components. It is crucial to use a high-quality camera that provides accurate and detailed images.
In addition to a thermal imaging camera, other equipment and tools may be required depending on the scope of the survey. These may include ladders, safety gear, flashlights, and documentation tools. It is important to ensure that all equipment is in good working condition and calibrated properly for accurate results.
Using the right equipment and tools is essential for conducting a successful thermographic survey. It ensures that potential issues are not overlooked and that accurate data is collected for analysis.
Conducting the Survey: Methodology and Techniques
Conducting a thermographic survey requires following a systematic approach to ensure accurate results. Elion’s team follows a well-defined methodology and uses proven techniques to conduct their surveys.
The first step in conducting a survey is to gather relevant information about the electrical system being surveyed. This includes obtaining electrical drawings, maintenance records, and any other available documentation. This information helps in understanding the layout of the system and identifying potential areas of concern.
Once the necessary information is gathered, the team starts scanning LT panels and transformers using a thermal imaging camera. They capture thermal images of various components, paying close attention to hotspots or abnormal heat patterns. These images are then analyzed for potential issues.
After completing the scanning process, the team compiles a detailed report that includes thermal images, analysis of potential issues, and recommendations for addressing them. This report is shared with the client for review and further action.
Analysis of Results: Identifying Issues and Recommendations
The results of the thermographic survey conducted by Elion for the five-star hotel in Amritsar, Punjab were analyzed to identify potential issues and provide recommendations for addressing them. The thermal images captured during the survey were carefully examined for hotspots or abnormal heat patterns.

FAQs
Q1: Why do hotels need transformer-specific thermography, not just panel scanning?
Hotels can have critical transformer assets supplying large and continuously operating loads such as HVAC systems, kitchens, lifts, lighting, and other essential services. Transformer-specific thermography allows inspection of transformer terminals, bushings, cable connections, and other accessible components for abnormal thermal patterns that may not be identified through routine LT panel scanning alone.
Q2: What is the cost of LT panel and transformer thermography for a hotel?
The cost depends on the number of LT panels and transformers, transformer capacity, accessibility, operating conditions, number of measurement points, and reporting requirements. A project-specific quotation is therefore more appropriate than a fixed price.
Q3: When should hotels schedule electrical thermography surveys?
Hotels should schedule thermography while electrical equipment is energized and carrying a meaningful operating load, because thermal abnormalities are easier to identify under representative load conditions. Surveys are typically incorporated into a periodic preventive-maintenance programme and may be scheduled more frequently for critical equipment or where previous hotspots have been identified.
Q4: What is the NFPA 70B threshold for transformer connections?
NFPA 70B should not be interpreted as prescribing one universal temperature threshold for every transformer connection. Thermographic findings need to be evaluated in context, considering load, ambient temperature, component type, temperature difference from comparable components, and the equipment manufacturer’s recommendations. A significant abnormal temperature differential should be investigated and appropriately prioritised.
Q5: How long does hotel transformer replacement typically take if one fails?
Transformer replacement time varies significantly depending on transformer capacity, availability of a replacement unit, site access, lifting and installation requirements, electrical isolation, testing, commissioning, and utility or statutory requirements. A planned replacement can be considerably faster than an emergency replacement where a suitable transformer is not immediately available.
