Auto ancillary manufacturing — components and parts supplied to vehicle OEMs — runs press-shop and welding equipment as dominant electrical loads, both of which draw heavy, cyclical current (presses in repeated stamping cycles, welding transformers in short high-current bursts) that stresses electrical connections differently than the continuous steady load of, say, an HVAC system. NFPA 70B recommends thermographic inspection specifically because cyclical heavy loads accelerate connection degradation compared to steady loads, making auto ancillary press-and-weld shops a facility type where thermography’s preventive value is especially high. At an auto ancillary unit in Udham Singh Nagar, Uttarakhand, Elion’s thermography survey scanned press-shop motor and control circuits, welding transformer connections, and compressed air compressor electrical systems — the specific high-cyclical-load points in this facility type.
Udham Singh Nagar’s established auto-component manufacturing base means facilities of this type are common in the region, and this case study’s findings pattern — connections stressed by cyclical rather than steady load — offers a useful reference point for similar auto ancillary operations facing comparable equipment-duty-cycle dynamics. This case study covers the specific thermography findings from the Udham Singh Nagar facility and the corrective priorities recommended.

Understanding the Importance of Electrical Thermography
Electrical thermography is a non-destructive testing technique that uses thermal imaging cameras to detect and measure the temperature variations in electrical systems. It works on the principle that faulty electrical connections or equipment tend to generate excess heat, which can be detected through thermal imaging.
Regular thermography services are essential for industrial units as they help in identifying potential electrical faults before they lead to accidents or downtime. By detecting hotspots, loose connections, or overloaded circuits, thermography audits can help prevent electrical fires, equipment failures, and production disruptions. This not only ensures the safety of workers but also improves the overall efficiency of the unit.
Benefits of Conducting a Thermography Service for Auto Ancillary Units
Thermography services offer several benefits specifically for auto ancillary units. These units often have complex electrical systems due to the use of heavy machinery and equipment. By conducting regular thermography audits, these units can reduce downtime by identifying and addressing potential electrical faults before they cause major disruptions in production.
Furthermore, thermography services can improve the efficiency of auto ancillary units by identifying areas where energy is being wasted due to faulty connections or overloaded circuits. By rectifying these issues, units can optimize their energy consumption and reduce their electricity bills.
Safety is another crucial aspect for auto ancillary units, as any accidents or fires can have severe consequences. Thermography audits help in ensuring the safety of workers by detecting potential electrical hazards and allowing for timely repairs or replacements.

FAQs
Q1: Why does cyclical electrical load accelerate connection degradation?
Press-and-weld manufacturing operations frequently subject electrical systems to rapid load fluctuations, repeated high-current demand, and frequent equipment start-stop cycles. These cyclical loads cause repeated heating and cooling of electrical connections, resulting in thermal expansion and contraction. Over time, this can loosen bolted joints, increase contact resistance, accelerate oxidation, and create localized hotspots. Infrared thermography helps detect these developing faults before they lead to equipment failure, production downtime, or electrical fires.
Q2: What equipment does thermography scan in an auto ancillary manufacturing plant?
A thermographic inspection of an automotive ancillary facility typically includes:
- HT and LT switchboards.
- Transformers and transformer terminations.
- Main Distribution Boards (MDBs) and Sub Distribution Boards (SDBs).
- Motor Control Centres (MCCs).
- Power Control Centres (PCCs).
- Bus ducts and busbar joints.
- Welding transformers and welding distribution panels.
- Press line electrical panels.
- Capacitor banks and APFC panels.
- Variable Frequency Drives (VFDs), soft starters, and servo drive panels.
- Compressor panels, DG panels, and critical production equipment supply panels.
The inspection identifies abnormal temperature rises that may indicate loose connections, overloaded circuits, phase imbalance, insulation deterioration, or failing electrical components.
Q3: How is welding transformer electrical stress different from steady load stress?
Unlike equipment operating under relatively constant electrical demand, welding transformers are exposed to short-duration, high-current pulses with frequent duty cycles. These repetitive current surges generate rapid thermal cycling, placing greater stress on windings, terminals, cable connections, insulation, and protective devices. As a result, welding transformers are more susceptible to overheating caused by loose connections, deteriorating contacts, or excessive loading. Regular thermographic inspections help identify these issues before they affect production reliability or equipment life.
Q4: How does this compare to the site’s other auto ancillary case study?
This case study may complement other automotive ancillary case studies on the website while focusing on a different manufacturing process, facility, or inspection scope. For example, one project may concentrate on press and welding operations, while another covers machining, painting, assembly, casting, forging, or general electrical safety. Linking related case studies allows readers to compare different operational environments while avoiding duplicate content by clearly describing each project’s unique objectives, findings, and recommendations.
Q5: How often should press-and-weld manufacturing electrical systems be scanned?
Most automotive manufacturers include annual infrared thermographic inspections as part of their preventive maintenance programme. However, high-duty electrical equipment such as welding transformers, press line feeders, MCCs, PCCs, HT/LT panels, bus ducts, and heavily loaded distribution systems is often scanned every six months or more frequently, depending on production intensity, equipment criticality, previous findings, and maintenance history. Inspection frequency should be determined through a documented risk-based maintenance strategy.
