Thermography audits for newspaper and commercial printing plants identify electrical faults in high-load press drives, web offset printing units, and continuous-run electrical systems that operate 20–24 hours daily — creating accelerated fault conditions invisible to standard inspection. According to NFPA 70B, printing and publishing facilities are classified as continuous-process industries requiring annual thermography due to their 24-hour electrical load cycling profile.
At a major newspaper printing plant in Noida, Uttar Pradesh (3 web offset printing lines, 1.4 MVA connected load, operating 22 hours daily to meet print deadlines), Elion’s thermography audit identified 9 electrical hotspots — including a critically overheating main press drive inverter terminal running 44°C above ambient, two transformer tap connections at 28°C above ambient, and an overloaded distribution board feeding the plate-making unit. Total corrective investment: ₹3.8 lakh. Avoided production risk: a single press line shutdown during peak evening print run would cost approximately ₹6.5 lakh in missed circulation revenue and emergency overtime.
Noida’s Phase 2 and Phase 4 industrial clusters house some of North India’s largest print media production facilities. UP’s industrial electricity tariff (UPCL HT supply at ₹7.50–₹9.00/kWh) makes electrical efficiency critical, and press line continuity is a zero-tolerance operational requirement — missed editions are unrecoverable commercial events. This case covers the complete thermography methodology, fault classification, and corrective action schedule.
A thermography audit for a newspaper or commercial printing plant (1–3 press lines) costs ₹40,000–₹1.1 lakh. It uses infrared cameras to scan press drive inverters, transformer connections, and distribution boards — identifying faults before they cause missed-edition shutdowns. Annual audits per NFPA 70B are recommended for 24-hour printing operations.

The Importance of Thermography Audit
A thermography audit is an essential tool for identifying potential electrical issues in manufacturing facilities. Electrical failures can lead to costly downtime, equipment damage, and even pose a safety risk to employees. By conducting regular thermography audits, businesses can proactively identify and address any potential issues before they escalate.
The potential risks and costs associated with electrical failures in manufacturing facilities are significant. Downtime can result in lost production, missed deadlines, and dissatisfied customers. Equipment damage can be expensive to repair or replace, and in some cases, may even lead to the complete shutdown of operations. Additionally, electrical failures can pose a safety risk to employees, potentially causing injuries or even fatalities.
What is Electrical Thermography?
Electrical thermography is a non-destructive testing technique that uses infrared imaging to detect and measure thermal patterns in electrical systems. It allows for the identification of hotspots, loose connections, overloaded circuits, and other potential issues that may not be visible to the naked eye.
The principle behind electrical thermography is based on the fact that electrical components generate heat when there is resistance or an imbalance in the flow of electricity. By using an infrared camera, thermographers can capture images that show variations in temperature across electrical systems. These images can then be analyzed to identify any abnormalities or potential issues.
Understanding Thermography Survey
A thermography survey involves the systematic inspection of electrical systems using infrared cameras to detect any anomalies or potential issues. During the survey, a trained thermographer will scan all electrical components, including switchboards, circuit breakers, transformers, and cables.
The equipment used in a thermography survey includes high-resolution infrared cameras, which can capture detailed images of thermal patterns. These images are then analyzed by the thermographer to identify any hotspots or abnormalities. In addition to the cameras, other tools such as temperature probes and data loggers may be used to gather additional information.
The Need for a Thermography Audit in Manufacturing
Manufacturing facilities face unique electrical challenges due to the high demand for electricity and the complex nature of their electrical systems. These challenges can include issues such as overloaded circuits, loose connections, and faulty equipment. A thermography audit can help identify and mitigate these challenges by providing a comprehensive assessment of the electrical system.
By conducting a thermography audit, manufacturing facilities can identify potential issues before they cause major problems. This proactive approach allows businesses to address any necessary repairs or maintenance, reducing the risk of downtime and equipment damage. Additionally, a thermography audit can help improve the overall efficiency and safety of the electrical system, leading to cost savings and increased productivity.

FAQs
Q1: Why is thermography especially important for newspaper printing plants?
A: Newspaper printing plants have three characteristics that make electrical faults uniquely damaging: (1) Zero-tolerance deadlines — a print line shutdown at 10pm during peak evening run cannot be recovered; missed editions mean lost circulation revenue and advertiser credits. (2) Continuous 20–24 hour operation — electrical connections undergo more thermal cycling in one month than most industrial facilities experience in a year. (3) High-current press drives — web offset press drives draw 200–600A per line, creating severe stress on connections that thermography uniquely detects.
Q2: What specific electrical components does thermography inspect in printing facilities?
A: In newspaper printing plant thermography audits, key inspection targets are: main press drive VFD (Variable Frequency Drive) and inverter terminal connections, transformer primary and secondary tap bolts, MCC panel busbars and circuit breaker terminations, plate-making and CTP (Computer-to-Plate) unit power feeds, chiller and HVAC plant room feeders (critical for ink temperature control), and ink drying system electrical heating elements. Press drive inverter terminals are the highest-failure component in printing plant electrical systems.
Q3: How much does thermography audit cost for a Noida printing plant?
A: Thermography audit costs for Noida printing and publishing plants: single press line facilities (small format) — ₹40,000–₹60,000; mid-size newspaper plants (2–3 press lines, 0.5–2 MVA load) — ₹60,000–₹1 lakh; large multi-press facilities (4+ lines, above 2 MVA) — ₹1–₹1.5 lakh. UP-based plants benefit from Elion’s NCR-Delhi presence reducing mobilisation costs versus outstation audit teams.
Q4: How does a thermography-identified fault cause a newspaper missed edition?
A: The failure cascade: a loose press drive inverter terminal (detectable at 20–30°C above ambient) progressively overheats during the print run. At 40–50°C above ambient, insulation breakdown accelerates. At 60–80°C, the insulation fails causing a short circuit — tripping the press line circuit breaker and shutting down the press mid-run. Emergency repair takes 4–8 hours minimum. For a daily newspaper with a 9pm press time, this means zero print run for the next day’s edition — lost circulation, advertiser credits, and distribution penalties.
Q5: What is the frequency recommendation for thermography in 24-hour printing operations?
A: NFPA 70B classifies continuous-process facilities (including 24-hour printing plants) as requiring annual thermography as minimum. For newspaper plants with single-source print infrastructure (no backup press), semi-annual thermography of press drive electrical systems is strongly recommended — the cost (₹40,000–₹60,000 per semi-annual survey) is negligible versus a missed-edition event. UP electricity regulations don’t mandate thermography frequency, but NFPA 70B compliance is increasingly cited by industrial fire insurers for premium calculation.
Q6: What are UPCL power factor requirements and how does thermography help compliance?
A: UPCL (Uttarakhand Power Corporation) and UP’s UPPCL (Uttar Pradesh Power Corporation) require HT consumers to maintain average monthly power factor above 0.90, with surcharges for lower values. Thermography identifies failing capacitor banks (detectable by localised heating) that cause power factor deterioration — repairing these restores power factor compliance and eliminates UPCL surcharges. For a Noida printing plant with ₹12 lakh monthly electricity bill, a 0.78 power factor costs ₹1.44 lakh/month in surcharges.
