4.注意事項1.測量三相異步電動機絕緣電阻時，不允許設備帶電時用兆歐表測絕緣電阻；測量完畢，應對設備進行放電，否則容易引起觸電事故。2.兆歐表未停止轉動之前，禁止用手觸及設備的測量部分或兆歐表接線柱。拆線時，也不可觸及引線的裸漏部分。 (1)直流法。在電流互感器的一次繞組（或二次繞組）兩端，通過按鈕開關接入1.5～3V干電池。假設一次繞組的首端L1接電池正極，尾端L2接電池負極；在二次繞組兩端接一低量程直流電壓表或電流表，儀表的正極接二次繞組的K1端，負極接K2端。 三相電機額定耗電量，按實際功率=電流×電壓×根 3計算。功率P=√3UIcosφ功率P乘以小時數就是用電量。三相電動機實際用電量,取決于實際負荷大小。可以測量實際電流，計算實際功率，再乘小時數，即可得到用電量.電機的額定功率是電機的額定輸出功率，而不是額定輸入功率。

固體/固態繼電器原理結構圖：（圖2）3、溫度繼電器溫度繼電器就是兩種熱系數相差懸殊的金屬或合金彼此牢固地復合在一起形成碟形雙金屬片,當溫度升高到一定值,雙金屬片就會由于下層金屬伸長大,上層金屬伸長小而產生向上彎曲的力,彎曲到一定程度便能帶動電觸點,實現接通或斷開負載電路的功能。

啟動按鈕分出一根上線到了器輔助觸頭的下端，也就是說啟動按鈕按不按器輔助觸頭下端一直是有電的，然后啟動按鈕又分出了一根下線到了輔助觸頭的上端，啟動按鈕就是控制這根線一瞬間有電的，再從器輔助觸。

做為絕緣監察用的電壓繼電器整定值為15—20伏。1）一般二次儀表的正常運行電壓是100V，為了達到這個目標，就將PT變比故意作成某種形式。對于中性點絕緣的系統：發生單相接地時，非故障相對地電壓升高到√3倍，且他們之間的夾角為60度，所以疊加出開口三角輸出電壓要變為原來的3倍。

這在高溫下尤為嚴重，在這種情況下可以在MT1和MT2間加一個RC緩沖電路來限制VD/DT，或可采用高速可控硅(晶閘管)。5、關于連續峰值開路電壓VDRM在電源不正常的情況下，可控硅(晶閘管)兩端的電壓會超過連續峰值開路電壓VDRM的最大值，此時可控硅(晶閘管)的漏電流增大并擊穿導通。 當元件中通過的電流超過整定電流值的20％時，熱繼電器應在20分鐘內動作。熱繼電器的整定電流大小可通過整定電流旋鈕來改變。選用和整定熱繼電器時一定要使整定電流值與電動機的額定電流一致。普通熱繼電器的“整定電流”通過旋鈕上的刻度來指示，只能確定一個大概數字，整定誤差較大。
