Innovation at VRT Power:Transformer Health and Monitoring Service
Transformers are very critical plant assets whose health is crucial to the facility operation. Moreover, transformers units installed at industrial plants are unique and complex in design. Periodic inspections and tests may not suffice in identifying potential developing issues, while oil analysis alone does not cover many failure modes.
To face this challenge, the VRT Transformer Health Monitoring Service
(THMS) offers an innovative approach to performance optimization, predictive analysis and disaster prevention.

At VRT Power innovation team led by Mr. Andre Shor, Chief Technology Officer, is working to improve and advance the field of transformers in the world.
There is a major concern about low frequency magnetic fields (ELF) in the vicinity of power transformers inside and outside of transformer rooms. The magnitude of magnetic field density is in direct proportion to the electrical current and opposite to the distance. The required electrical current of consumers is according to the local consumption and the standard distribution voltage – unchangeable data. Thus, to reduce the magnetic field magnitude one needs to move the source of magnetic field away from populated areas.
VRT Power engineers have designed transformers with low magnetic field.
The primary purpose of this special designed transformer is to minimize the magnetic field to which human beings may be exposed by arranging the source of magnetic field as low as possible on the transformer body.
VRT Power has manufactured and installed a number of 630KVA, 22/0.4KV transformers with low magnetic field. The measured magnetic fields were much lower than permitted by International Commission on Non-Ionizing Radiation Protection (ICNIRP) guidelines.
