The design of the test facility and its capabilities and operation are described.","PeriodicalId":428411,"journal":{"name":"Proceedings of Electrical/Electronics Insulation Conference","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134134218","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}

The pump can generate vibrations, particularly when operated under load. This vibrational energy is converted into radiated sound energy through the large surface of the chassis, kickplate and sidewalls of the cabinet. Structure-borne noise of the pumps is dominant around 100 Hz. The pulsating suction noise of the drain pumps is one of the reasons for airborne noise in the appliances. Suction noise is caused by sucking air when most of the water has been drained. The rest of the sources of the airborne noises are the fan blade and (partially) the impeller blades.","PeriodicalId":428411,"journal":{"name":"Proceedings of Electrical/Electronics Insulation Conference","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114831482","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}

It is shown how these requirements are fulfilled by new developments in ferrite materials and core shapes and which are the criteria for selection. As further support to the application engineer, PC software is presented, which enables the user to calculate power losses coreshape/material related without using the \"material data sheets\", which are based on ring core measurements.","PeriodicalId":428411,"journal":{"name":"Proceedings of Electrical/Electronics Insulation Conference","volume":"65 50","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120817904","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}

The results show that the contribution of hydrolytic attack on the polymer itself is insignificant in salt water bath failures. Samples with similar dielectric strength and resistivity give vastly different results in salt water. Failures in water immersion tests occur, not because of the attack of water, but because of its availability as a conductor. This conductor seeks out flaws and weak spots in the film, shorting them to ground or to other flaws.","PeriodicalId":428411,"journal":{"name":"Proceedings of Electrical/Electronics Insulation Conference","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129382781","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}
