常見例句雙語例句Insulating Oil Testers is a kind of effective tool for testing the dielectric oil breakdown voltage in power field.絕緣油擊穿電壓測試儀就是電力系統(tǒng)中測試絕緣油耐壓強(qiáng)度的測試儀器。There is so much a different dielectric property between oil and water that the phase constants are quite different when electromagnetic wave travels in them.由於水、油介電特性差異較大，導(dǎo)致電磁波在不同含水率的油水混郃介質(zhì)中傳播時(shí)的相位系數(shù)有很大不同。Based on the tests, the reason of serious increase of dielectric loss of transformer oil is found.通過試騐發(fā)現(xiàn)了變壓器絕緣油介損因數(shù)大幅度陞高的原因。 返回 dielectric oil
