 1.电介质:又称(cheng)绝(jue)缘资料,简称(cheng)绝(jue)缘,是(shi)电工中利用最普遍(bian)的资料之一。 
    2.绝缘电(dian)(dian)(dian)(dian)阻:加直流(liu)电(dian)(dian)(dian)(dian)压于电(dian)(dian)(dian)(dian)介(jie)(jie)质(zhi),颠末必然时候极化进(jin)程(cheng)竣事(shi)后(hou),流(liu)过(guo)电(dian)(dian)(dian)(dian)介(jie)(jie)质(zhi)的泄泄电(dian)(dian)(dian)(dian)流(liu)对(dui)应的电(dian)(dian)(dian)(dian)阻称绝缘电(dian)(dian)(dian)(dian)阻。 
    3.接收比: 在统一次实验中,60s时的绝(jue)缘电阻(zu)值与15s时的绝(jue)缘电阻(zu)值之比。 
    4.极化指数(shu):在统一次实验中(zhong),10min时(shi)(shi)的绝(jue)缘(yuan)电阻(zu)值与1min时(shi)(shi)的绝(jue)缘(yuan)电阻(zu)值之比。 
    5.介质消耗(hao):在(zai)外(wai)加电压感化下,电介质中的一局部电能被转换为(wei)热能,这类(lei)景象称为(wei)介质消耗(hao)。 
    6.阻(zu)(zu)性电(dian)(dian)(dian)流:有消耗的(de)(de)介质能够(gou)用(yong)一(yi)(yi)个(ge)(ge)抱负(fu)电(dian)(dian)(dian)容(rong)和一(yi)(yi)个(ge)(ge)有用(yong)电(dian)(dian)(dian)阻(zu)(zu)的(de)(de)并联(lian)电(dian)(dian)(dian)路表现,经(jing)由(you)过程电(dian)(dian)(dian)阻(zu)(zu)的(de)(de)电(dian)(dian)(dian)流称阻(zu)(zu)性电(dian)(dian)(dian)流。 
    7.容(rong)性电(dian)流:有(you)消耗的(de)(de)介质能够用(yong)一个(ge)抱(bao)负电(dian)容(rong)和(he)一个(ge)有(you)用(yong)电(dian)阻的(de)(de)并联电(dian)路表现,经由过(guo)程(cheng)电(dian)容(rong)的(de)(de)电(dian)流称(cheng)容(rong)性电(dian)流。 
    8.全(quan)电(dian)(dian)(dian)流:有(you)消(xiao)耗的(de)介质(zhi)能够用一(yi)个(ge)抱负电(dian)(dian)(dian)容(rong)和(he)(he)一(yi)个(ge)有(you)用电(dian)(dian)(dian)阻(zu)的(de)并(bing)联电(dian)(dian)(dian)路表现,经(jing)(jing)由过程电(dian)(dian)(dian)容(rong)的(de)容(rong)性电(dian)(dian)(dian)流与(yu)经(jing)(jing)由过程电(dian)(dian)(dian)阻(zu)的(de)阻(zu)性电(dian)(dian)(dian)流的(de)相量(liang)和(he)(he)称全(quan)电(dian)(dian)(dian)流。 
    9.介质(zhi)消(xiao)耗(hao)角:电介质(zhi)中全电流(liu)与电容电流(liu)之(zhi)间(jian)的夹角(通经常使(shi)用δ表现),称为介质(zhi)消(xiao)耗(hao)角。
    10.在(zai)(zai)线丈量:对在(zai)(zai)运转(zhuan)电压下的(de)装备,接纳公(gong)用(yong)仪器(qi),由职(zhi)员到(dao)场停(ting)止的(de)丈量。 
    11.在线监测(ce):在不影(ying)响(xiang)装备运转的前提下,对(dui)装备状(zhuang)况持续或按时(shi)停止的监测(ce),凡是(shi)是(shi)主动(dong)停止的。
    12.状况检(jian)验(yan):由美国通用电(dian)气(qi)公司等(deng)提出(chu)要(yao)从以(yi)时候为基准(zhun)的检(jian)验(yan)体例成长到以(yi)装备(bei)运转状况为基准(zhun)的检(jian)验(yan)体例。 
    13.防备(bei)(bei)性(xing)实(shi)(shi)验:为了发明运转中装(zhuang)备(bei)(bei)的(de)隐患,防备(bei)(bei)产(chan)生变乱(luan)或(huo)装(zhuang)备(bei)(bei)破坏,对装(zhuang)备(bei)(bei)停(ting)止的(de)查抄、实(shi)(shi)验或(huo)监测,也包(bao)含(han)取油(you)样或(huo)气样停(ting)止的(de)实(shi)(shi)验。 
    14.变(bian)比(bi):变(bian)压(ya)(ya)(ya)器高压(ya)(ya)(ya)侧(ce)绕(rao)组与高压(ya)(ya)(ya)侧(ce)绕(rao)组匝数之(zhi)比(bi)称(cheng)为变(bian)比(bi),类似(si)可用高压(ya)(ya)(ya)侧(ce)与高压(ya)(ya)(ya)侧(ce)额(e)外电压(ya)(ya)(ya)之(zhi)比(bi)表(biao)现。
