The fundamental characteristics of the proposed sensor, as a PD detector, were temperature compensation and direction independence. The proposed high-resolution PD detector operated based on the FBG wavelength shift. It is necessary to evaluate the physical parameters of the sensor to achieve the best results. Therefore, in this paper, the detected signal strength was investigated for different angles and temperatures. A Teflon hollow mandrel and two FBGs attached to the inner and outer surfaces of the hollow mandrel were chosen as the inner transformer PD detector. The changes in the sensor output were less than 0.4 mV and 0.5 mV for direction variations and a temperature variation of 14 \u00b0C (degrees Celsius), respectively. Consequently, the proposed sensor could be successfully employed for the detection of a transformer PD signal.<\/jats:p>","DOI":"10.3390\/s19235285","type":"journal-article","created":{"date-parts":[[2019,12,2]],"date-time":"2019-12-02T10:50:45Z","timestamp":1575283845000},"page":"5285","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["High-Resolution FBG-Based Fiber-Optic Sensor with Temperature Compensation for PD Monitoring"],"prefix":"10.3390","volume":"19","author":[{"given":"Mohsen","family":"Ghorat","sequence":"first","affiliation":[{"name":"Department of Electrical Engineering, Amirkabir University of Technology, Tehran 158754413, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1521-790X","authenticated-orcid":false,"given":"Gevork B.","family":"Gharehpetian","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, Amirkabir University of Technology, Tehran 158754413, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hamid","family":"Latifi","sequence":"additional","affiliation":[{"name":"Laser and Plasma Research Institute and Physics Department, Shahid Beheshti University, Tehran 1983969411, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maryam A.","family":"Hejazi","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, University of Kashan, Kashan 8731753153, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8078-9173","authenticated-orcid":false,"given":"Mehdi","family":"Bagheri","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, Nazarbayev University, Nur-Sultan 010000, Kazakhstan"},{"name":"National Laboratory Astana, Center for Energy and Advanced Material Science, Nazarbayev University, Nur- Sultan 010000, Kazakhstan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,11,30]]},"reference":[{"key":"ref_1","unstructured":"Zargari, A., and Blackbum, T.R.
