What is the purpose of filming cables?

The visitors at Railway Technology Days in Częstochowa on June 13th should pay their attention to employees of PKP Energetyka S.A. carrying cameras. Although they look like normal cameras, they have a different use. They are thermal imaging cameras allowing, among other things, for the remote identification of damage to electric conductors. In the thermal image, various colours represent various surface temperatures, which helps the user to identify potential issues and prevent failure. Major parameters of the image can be modified in the attached software in order to optimise the image and obtain as much data as possible without repeating the inspection.

The major advantages of thermal imaging cameras:

  • instant, contactless generation of detailed images of temperature distribution, allowing for the prompt identification of hot spots;
  • fully radiometric measurements, allowing a detailed analysis of the temperatures and monitoring the temperatures of individual elements;
  • a broad range of industrial applications and measuring range up to 250 °C;
  • a large colour LCD display with a clear image of the temperature distribution, including menu functions;
  • easy and comfortable one-hand operation;
  • rapid displaying and saving of images;
  • InsideIR software allows for the storage and analysis of thermographic images and report generation.

Thermal imaging cameras can be used to assess the quality of insulation works, without intervention, which is a great advantage, e.g. in construction. The effectiveness of thermal imaging is so high that a number of insurance companies recommend the use of thermal imaging and grant discounts when thermal imaging inspections are carried out regularly.

Thermal imaging cameras are not the only method employed by PKP Energetyka S.A to identify electrical defects. The company has also specialised laboratory vehicles, which will be also demonstrated during Railway Technology Days in Częstochowa. Instrumentation installed on board of such laboratory vehicles can be used for the following tasks:

  1. Preliminary identification of cable damage by
    • the pulse-echo method
    • KLV method with luminous arc stabiliser
    • current decoupling
    • voltage decoupling.
  2. Identification of the detailed location using a surge generator in the following ranges: 0 – 8 kV, 0 – 16 kV and 0 – 32 kV.
  3. Voltage tests (SEBA KMT – 70 kV).
  4. Afterburning – converting high Ohm damage into low Ohm damage.
  5. Identification of cable coating damage.
  6. Detection (determining the route of the cable line) and identification of cables.

Railway Technology Days – a periodic family event aiming at the presentation of rail-related matters to all interested parties. This year’s edition will be held in four Polish cities: Warsaw, Gdańsk, Częstochowa and Gliwice. During the family event held on Sunday, June 13th, from 10:00 to 17:00, all visitors will find something to their liking. Kids can check out large rail cars and participate in numerous games and competitions. Older visitors will learn about the details of presented rolling stock and talk to rail workers about their jobs. The event will also include live performances of children bands. Relevant information will be published on an on-going basis on the website

Railway Technology Days are organised by: the Association of Communication Engineers and Technicians of the Republic of Poland, PKP S.A, PKP Energetyka, PKP PLK, Telekomunikacja Kolejowa, PKP Cargo, PKP SKM in Trójmiasto, CS Szkolenie i Doradztwo, Railway Museum, PKP Intercity, KOW and Wars. Railway Technology Days are held under the auspices of Andrzej Wach, President of PKP S.A., President of the capital city of Warsaw, President of the city of Gliwice, Pomorskie Province Governor. Media sponsorship is provided by Kolej TV, Kurier Kolejowy, TSL Biznes,, Miasto Dzieci and ITV Gliwice.
