Moisture & Oxygen Management, Online Monitoring, Diagnostics and Life management of Power Transformers

New perspective on transformer life management by “remote monitoring” and controlling moisture and oxygen of its insulation system.


The primary focus of the 4-day Virtual instructor-led Training will be on the sources, causes and effects of moisture & oxygen on transformer insulation life and incipient failure modes. It will be demonstrated that laboratory periodic oil analysis is limited and not always adequate, while continuous online monitoring has increasing potential and many significant advantages.

Moisture & Oxygen Management:

From sources of moisture and oxygen ingress to methods of their removal this masterclass explores various aspects of transformers life cycle management. There will be focus on the area of detrimental effects of moisture and oxygen on transformer insulation, methods of water and oxygen measurement and assessment. Substantial time will be dedicated to various parameters used to describe moisture in oil/paper insulation. The trainer will take the audience through a number of transformer failure cases caused by the presence of water. He also will provide an in-depth overview of online as well as off-line water and oxygen measurement techniques used by leading electric utilities and analytical laboratories. Variety of water removal methods and associated equipment will be discussed and studied in detail and on practical examples. The audience will learn about many innovative solutions brought in the field of predictive condition monitoring of power transformers.

Online monitoring & diagnostic:

Transition to digital utility (smart grid, industry 4.0, etc) is immanent and it is hard to imagine that in the very near future engineers will not be exposed to online monitoring of their essential assets, such as transformers, power lines and substation switchgear. As technology keeps evolving with new features (communication protocols, sensors, advanced analytics, etc) on a daily basis, the trainer will be discussing new ways of data management and delivery, complementing traditional SCADA with Industrial Internet of Things (IIoT) with the emphasis on architecture, reliability and security. Successful implementation of online monitoring, fault identification and isolation, transformer life extension will also be covered by the trainer.

Participants will have the opportunity to experience real time monitoring as the trainer will demonstrate the IIoT based transformer monitoring system - the first in the world, which uses non-conventional innovative methods for temperature, moisture and oil quality monitoring.

Choosing the best potential vendor:

A number of transformer online monitoring solutions providers is increasing. More and more owners and operators of electrical equipment make decision towards incorporating online monitoring technologies in their asset management practices. There are also new international standards requiring now to specify basic means of online monitoring into transformer purchasing agreements. A choice of the right solution has never been more challenging as there are no reviews or web resources where you could go and find out a recommendation on selection of the most appropriate, reliable, and cost-effective equipment for your needs. This course will give attendees techniques and strategy on how to select right partner/OEM and never regret about the investment.

The Virtual instructor-led Training is filled with numerous case studies, practical industry examples and real time monitoring demonstrations. Participants will be able to expand on the knowledge gained elsewhere and will develop new perspective on the whole subject of transformer life cycle management.
