Back by popular demand, LumaSense is hosting a webinar, Practical Online DGA Practices and Applications, on May 23rd at 1:00 EDT. This informative webinar is not a sales pitch, but rather informative and explains how continuous monitoring using dissolved gas analysis (DGA) and various interpretation tools allow utilities to get a more complete picture of transformer and LTC health.
As an industry leader in process monitoring for all areas of steel manufacturing, we know how thermal imagers and pyrometers can provide dependable monitoring of critical parameters for productivity and product quality. Using non-contact industrial solutions allows manufacturers to ensure raw materials are safely transported, reach the right characteristics during the making process, and remain high quality during finishing.
When exposed to high temperature, insulating paper found in transformers breaks down and results in a reduction of the useful life of the transformer. Monitoring temperature of the insulating paper via a winding hot spot ensures the insulating paper is not exposed to high temperatures and helps minimize damage.
Conventional methods of monitoring the winding hot spot use calculations to simulate the temperature, but do not measure it. These winding temperature indicators (WTIs) infer the hot spot temperature by measuring the transformer load on a single phase and the surrounding oil temperature and then apply a model. Other issues with the WTIs include a long lag time (up to 5 hours) and actual temperature variance (up to 20 °C).
When it comes to dissolved gas analysis, online monitoring is a cost-effective method but requires a robust method of gas extraction in order to accurately detect and measure present gases. The two primary methods for extracting the gases found in transformer insulating oil are vacuum or membrane based.
Vacuum extraction requires using a large vacuum pump which runs the risk of pulling oil into the gas analysis chamber. It also requires maintenance on pumps (that will someday need replacement). With membrane-based methods such as the “spaghetti tube” or flat sheet, there is a risk of breaking the membrane. Additional supports can be added to the flat sheet membrane, but there is additional risk of impairing the gas transfer properties.
Monitoring Sulfur Recovery Units (SRUs), Sulfur Burners, and Thermal Oxidizer Furnaces using both the gas flame and refractory temperature is an effective method to control the furnace process temperatures.
LumaSense delivers many innovative temperature and gas sensing instruments for monitoring transmission and distribution assets. From gas monitoring with Non-Dispersive Infrared (NDIR) and Photoacoustic Spectroscopy (PAS) technologies or temperature monitoring with infrared and fiber optics, our broad range of technology expertise allows us to offer industry professionals opportunities to implement cost-effective online monitoring solutions to manage and maintain equipment.
Transformer Winding Hot Spot Monitoring – More than 40 years ago, LumaSense pioneered the field of fiber optic winding hot spot measurements with Fluoroptic® technology. Monitoring with fiber optics enables operators to accurately measure the actual hot spot temperature in real-time.
Transformer and LTC DGA Monitoring – With NDIR-based instruments, operators can perform automated, remote dissolved gas analysis to detect key fault gases and perform analysis on the condition of the transformer or load tap changer.
Substation Asset Monitoring – Infrared tools such as thermal imagers and pyrometers enable utilities to remotely monitor specific connections and assets such as transformers, bushings, and capacitor banks in real-time.
SF6 Leak Detection – Using PAS for SF6 leak detection creates a highly accurate, sensitive, and reliable solution to limit the emissions of insulating gas found in switchgears.

Engineers and building professionals often need to balance energy efficiency with optimized air quality. Heating, ventilation, and air conditioning (HVAC) systems found in various industries such as hospitals, laboratories, and passenger cabins, often need to perform to specific standards with targeted air exchange rates. Professionals can determine the appropriate air exchange rate using tracer gas.
When we introduced our new ThermalSpection 724 (TS724) system, we included the MCL640 camera to gain better resolution (640 x 480). Our customers have appreciated this upgrade because the resolution really makes a difference in the clarity and quality of the images.
