Dear Reader,
In the last few months, everyone could have realised that power supply and communication infrastructure are essential for the functioning of modern society. We in our industry know that this is normally the case. However, under the conditions of the crisis we have recently gone through, everyone could have become aware of this. Governments have also recognised this importance of power supply infrastructure and it has been a blessing for many businesses in our field since transformers are at the core of the power system.
Partial discharge monitoring of power transformers by UHF sensors
PD measurement is suitable to detect damages in the insulation of power transformers at an early stage which helps minimising the risk of failure
FLEETSCAN 2D: Your fleet at a glance
MR has developed FLEETSCAN 2D, a scientific solution for objective and independent condition assessment of power transformers
60 YEARS OF RANCAN
RANCAN SRL is an Italian company, and also a Global leader in manufacturing of high quality laminated densified wood used in many industrial sectors
Sulfur corrosion phenomena
Sulfur corrosion phenomenon that damages copper inside a transformer is quite old since it was observed almost immediately after implementing mineral oils.
MAXEI, your partner 4.0 to optimise transformer oil treatment
MAXEI offers advanced, flexible, and custom solutions for transformer oil processing that meets Industry 4.0 paradigm
Standards relevant to transformers – Part II
AIEE, founded in 1884, treated transformer related topics with great care, forming a separate committee for transformers in 1918
On-site modernisation of power transformers
On-site service or repair works can extend the trouble-free lifetime of transformers by up to 15 years
Transformer core stacking automation for smart manufacturing in the digitalisation era
GEORG developed a portfolio of autostack solutions for automatic core stacking of distribution and power transformers
Advanced analytics for transformer asset management
It's hard to estimate the transformers' reliability, probability of failure, and to plan activities without modern calculation methods and algorithms.
Detection of winding inter-turn faults – Part III
An inter-turn fault is one of the leading causes of power transformer failures; it can be detected using sweep frequency response analysis
Refining bushing power factor and capacitance analysis through statistics
Approach for the diagnostic analysis of the high-voltage bushings uses power factor and capacitance measurements; values are compared with the benchmark data
