Power transformers are one of the most important and critical components in power system networks. During its long service life, the transformer undergoes various stresses (electrical, mechanical, thermal, chemical etc.) which eventually degrade its dielectric as well as mechanical characteristics. The deterioration of transformer insulation characteristics reduces its dielectric strength, whereas winding deformation can result in internal faults. Gradual degradation of insulation characteristics and winding faults within the transformer during its service life can result in catastrophic failure and subsequently power interruption at the consumer’s end. The undesired interruption of power supply affects the production rate in heavy industries, which may result in huge monetary loss. In order to ensure a reliable power supply, the condition of transformers should be assessed regularly through employing advanced monitoring techniques. This Special Issue will cover the investigation of dielectric and mechanical characteristics of power transformers which are in service for a long period and are on the verge of ending their operating life. This Special Issue also invites contributions focused on the development of advanced techniques for monitoring the electrical characteristics and winding deformation of transformers for their reliability assessment to investigate further use in power system networks. Topics of interest for publication include but are not limited to:
- Investigation on moisture profile and aging characteristics of power transformer insulation;
- Diagnosis by chemical parameters;
- Dielectric spectroscopy in the time and frequency domain;
- Partial discharge diagnosis;
- Investigation on winding faults within transformers;
- Frequency response analysis of transformer windings;
- Reliability assessment.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Energies is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
