Hotline of power engineering specialists:
A new device has appeared in the arsenal of specialists of diagnostic crews of IDGC of Centre – Voronezhenergo division - a utility poles tester "LIS-U". This device allows to check the condition of 0.4-10 kV power lines for estimation of their residual life and elimination of risk of injury to technical personnel when climbing a pole.
Checking poles for safety and durability is stipulated in the safety regulations, electricians are obliged to conduct it before climbing a pole and starting work. Old methods of diagnostics take a long time, which slows down the repair and restoration work on power lines, and therefore, increase the duration of breaks in the electricity supply to consumers.
The use of the LIS-U tester for this procedure does not require preparatory work and takes about 10 minutes. The electrician brings the device close to the pole, and another hits it several times with a special hammer. The results of the analysis, which includes any changes related to the internal structure of the material from which the pole is made in the developed format are displayed and recorded in the internal memory of the device.
Specialists of the Voronezh branch of IDGC of Centre have already assessed the convenience of working with the device "LIS-U". "The fact that the data of surveys of each pole are stored in the device memory and can also be transferred to a computer allows us to create electronic records of overhead power lines to monitor the dynamics of aging and timely planning for their replacement," stressed the head of the diagnostics service of Voronezhenergo Oleg Okunev.
