With the advent of new ester-based fluids, new standards have been developed that impact selection, installation and maintenance of liquid-filled transformers. This article will focus on established standards for both factory and field testing and recommended tests during scheduled rotational outages. Typical ratings for distribution substation transformers applied in process industries range from 112.5 kVA through 10,000 kVA three-phase, at 50 or 60 Hertz, with primary voltage at 34,500 volts and below and secondary voltage at 4,160 volts and below. Not included in the scope of this paper are dry-type distribution transformers, pad-mounted distribution transformers or power transformers with ratings up to 100,000 kVA and 230 kVA. Field testing recommendations focus on dissolved gas analysis (DGA) testing and understanding/trending test results will be covered. A case study outlining recent testing, results and lessons learned for an integrated paper mill in the U.S. Pacific Northwest will be reviewed.","PeriodicalId":337924,"journal":{"name":"2021 IEEE IAS Pulp and Paper Industry Conference (PPIC)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121854137","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Each of these islands presents their own, unique set of unit operations; but, perhaps not surprisingly, you can see similar unit operations in various industries besides pulp and paper. For example, the powerhouse equipment, besides the main difference being that the fuel is “black liquor”, the equipment can be found in any other industrial power plant. In the paper machine “island”, the use of cascaded variable-speed drives to control the paper sheet tension is also seen in the draw line of a steel, textile, or fiber mill. And, as a final example, the effluent treatment facility of the paper mill has many of the same equipment you will find in a municipal water/wastewater plant.Several examples of specific control systems optimization included for each of these “islands” include chemical savings in the lime kiln and causticizing, pulping, screening and refining, washing, and bleaching processes of the pulp mill; energy savings in recovery boiler sootblowing and the lime kiln, pulp stock preparation including cleaning and refining and the paper pressing and drying sections of the paper mill; and the environmental savings involved in effluent treatment and recycling water.Lessons learned:1.What is an Autonomous Mill?2.What is a Digital Twin?3.understand the equipment and the processes in a pulp and paper mill4.understand the similarities to other industries5.understand specific areas where control system optimization can decrease costs and/or increase production","PeriodicalId":337924,"journal":{"name":"2021 IEEE IAS Pulp and Paper Industry Conference (PPIC)","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123953457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
