◆工控產品芯片封裝的內部連接
◆工控產品封裝引腳與PCB的連接。典型連接器IC插座。
◆印制電路與導線或印制板的連接。典型連接器為印制電路連接器。
◆底板與底板的連接。典型連接器為機柜式連接器。
◆設備與設備之間的連接。典型產品為圓形連接器。
◆接觸電阻高質量的電連接器應當具有低而穩定的接觸電阻。連接器的接觸電阻從幾毫歐到數十毫歐不等。
◆絕緣電阻衡量電連接器接觸件之間和接觸件與外殼之間絕緣性能的指標，其數量級為數百兆歐至數千兆歐不等。
◆抗電強度或稱耐電壓、介質耐壓，是表征連接器接觸件之間或接觸件與外殼之間耐受額定試驗電壓的能力。

組合式電流電壓互感器。組合式互感器由電流互感器和電壓互感器組合而成，多安裝于高壓計量箱、柜，用作計量電能或用作用電設備繼電保護裝置的電源。組合式電流電壓互感器是將兩臺或三臺電流互感器的一次、二次繞組及鐵心和電壓互感器的一、二次繞組及鐵心，固定在鋼體構架上，浸入裝有變壓器油的箱體內，其一、二次繞組出線均引出，接在箱體外的高、低壓瓷瓶上，形成絕緣、封閉的整體。一次側與供電線路連接，二次側與計量裝置或繼電保護裝置連接。根據不同的需要，組合式電流電壓互感器分為V/V接線和Y/Y接線兩種，以計量三相負荷平衡或不平衡時的電能。
電力系統為了傳輸電能，往往采用交流電壓、大電流回路把電力送往用戶，無法用儀表進行直接測量。互感器的作用，就是將交流電壓和大電流按比例降到可以用儀表直接測量的數值，便于儀表直接測量，同時為繼電保護和自動裝置提供電源。電力系統用互感器是將電網高電壓、大電流的信息傳遞到低電壓、小電流二次側的計量、測量儀表及繼電保護、自動裝置的一種特殊變壓器，是一次系統和二次系統的聯絡元件，其一次繞組接入電網，二次繞組分別與測量儀表、保護裝置等互相連接。互感器與測量儀表和計量裝置配合，可以測量一次系統的電壓、電流和電能；與繼電保護和自動裝置配合，可以構成對電網各種故障的電氣保護和自動控制�；ジ衅餍阅艿暮脡模�直接影響到電力系統測量、計量的準確性和繼電器保護裝置動作的可靠性。
