SSU76電(dian)(dian)(dian)(dian)壓(ya)(ya)監(jian)控繼電(dian)(dian)(dian)(dian)器能使機(ji)械、設(she)(she)備(bei)和(he)系統(tong)(tong)獲得很大(da)程(cheng)度的(de)保(bao)護，這意味著電(dian)(dian)(dian)(dian)壓(ya)(ya)故障可以(yi)被(bei)及早(zao)地檢(jian)測(ce)出來(lai)，并(bing)在造成更大(da)損(sun)失之前予(yu)以(yi)適當的(de)處理。監(jian)控繼電(dian)(dian)(dian)(dian)器主要可用于(yu)以(yi)下幾個方面：相(xiang)序（電(dian)(dian)(dian)(dian)動(dong)機(ji)轉向(xiang)錯誤）；斷(duan)相(xiang)（熔斷(duan)器熔斷(duan)、控制電(dian)(dian)(dian)(dian)源故障、電(dian)(dian)(dian)(dian)機(ji)單向(xiang)運行導致的(de)過(guo)熱(re)(re)）；相(xiang)不(bu)對(dui)稱（由于(yu)電(dian)(dian)(dian)(dian)壓(ya)(ya)不(bu)均(jun)(jun)勻或斷(duan)相(xiang)而引起的(de)電(dian)(dian)(dian)(dian)機(ji)過(guo)熱(re)(re)、電(dian)(dian)(dian)(dian)源負載不(bu)均(jun)(jun)衡(heng)）、低電(dian)(dian)(dian)(dian)壓(ya)(ya)（電(dian)(dian)(dian)(dian)機(ji)電(dian)(dian)(dian)(dian)流增大(da)導致過(guo)熱(re)(re)、設(she)(she)備(bei)意外復位、電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)壓(ya)(ya)不(bu)足）；過(guo)電(dian)(dian)(dian)(dian)壓(ya)(ya)（設(she)(she)備(bei)由于(yu)電(dian)(dian)(dian)(dian)源過(guo)電(dian)(dian)(dian)(dian)受損(sun)、設(she)(she)備(bei)或系統(tong)(tong)接入高電(dian)(dian)(dian)(dian)壓(ya)(ya)）；絕緣監(jian)測(ce)（檢(jian)測(ce)未接地設(she)(she)備(bei)和(he)系統(tong)(tong)的(de)絕緣電(dian)(dian)(dian)(dian)阻）。
