Monitoring the Winding Hot Spot

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).

Learning About DGA Extraction Methods

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.

Innovative Solutions for Transmission & Distribution

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.

Learn more about these solutions on our website or visit us at the upcoming Middle East Electricity show March 6-8 in Dubai. Talk with our experts and learn more about these technologies at Stand Z3.E17.

Using Tracer Gas to Analyze Ventilation Performance

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.

E2T: A Leader in the Petrochemical Industry

LumaSense Anniversary - 10 Years

Over the last year, we’ve been celebrating our 10th Anniversary by sharing the story behind each of our acquisition brands that made us the innovative leader we are today.

logo_e2tE2 Technologies (E2T) was founded in Ventura, California in 1974 and has been well recognized in the petrochemical industry for more than 40 years. E2T is known as a specialist in the Sulfur Furnace Temperature (SRU) application.

Mikron Infrared acquired E2 Technologies in 2002, which enabled Mikron to further solidify its presence as a major supplier in the non-contact point temperature measurement market and significantly strengthen its competitive position. LumaSense continues to offer solutions for SRU applications and high temperature furnace applications as well as flare pilot monitoring.

QUASAR Products
Mikron E2T designed the M7000SR Series for continuous and instantaneous measurement of Refractory Temperature (RT), Gas Temperature (GT), and Integrated Temperature (FF) in the vessel away from the heat, vibration, and corrosive gases. The M7000SR paved the way for today’s E2T Quasar M8100 Flare Pilot Monitor.

PULSAR Products
E2T started offering the PULSAR for SRU monitoring in the late 1970’s and LumaSense introduced the latest PULSAR product last year. The PULSAR 4 reports both gas and refractory temperatures measurements simultaneously and corrects for Flame Transparency errors with our proprietary Flame Measurement Algorithm (FMA).
