style="text-indent:25px">不同型號兆歐表的量程和示值的刻度方法不同，刻度分辨力不同，測量準(zhǔn)確度等級不同，都會引起示值間的差異。為了保證對電力設(shè)備的準(zhǔn)確測量，應(yīng)避免選用準(zhǔn)確度低，使用不方便的搖表。 3、試品大多含容性分量，并存在介質(zhì)極化現(xiàn)象，即使測試條件相同也難以獲得理想的數(shù)據(jù)重復(fù)性。 4、測量時，絕緣介質(zhì)的溫度和油溫應(yīng)與環(huán)境溫度一致，一般允許相差±5%。 5、應(yīng)在特定時間段的允許時間差范圍內(nèi)，盡快地讀取測量值。為使測量誤差不高于±5%，讀取R60S的時間允許誤差±3S，而讀取15S的時間不應(yīng)相差±1S。 6、高壓測試電源非理想電壓源，重負(fù)荷時，輸出電壓低于其額定值，這將導(dǎo)致單支路直讀測量法兆歐表測量準(zhǔn)確度因轉(zhuǎn)換系數(shù)的改變而降低。這種改變因兆歐表測試電源負(fù)荷特性不同而異。 7、不同動態(tài)測試容量指標(biāo)的兆歐表，試驗電壓在試品上的建立過程與對試品的充電能力均存在差異，測量結(jié)果也會不同，使用低于動態(tài)測試容量指標(biāo)門限值的兆歐表測量時，由于儀表存在慣性網(wǎng)絡(luò)導(dǎo)致示值響應(yīng)速度福祿克絕緣電阻測試儀。河北yd9820a絕緣電阻測試儀</p><p
