致茂接地連結(jié)測試器 19572產(chǎn)品簡介
19572 是專門測量接地電阻之量測儀器,電阻量測范圍由0.1~510mΩ,操作簡單、體積輕巧,適用于生產(chǎn)線之接地量測,可提供高可靠度及穩(wěn)定的測試結(jié)果,并具內(nèi)建式電阻補(bǔ)償功能,是一臺經(jīng)濟(jì)、實用的接地測試器。
接地電阻測量儀是用來測量接地系統(tǒng)中的接地電阻的儀器。在電氣工程中,接地電阻是一個重要的參數(shù),用于評估接地系統(tǒng)的質(zhì)量和性能。
接地電阻測量儀通常使用了一種稱為“四線法"的技術(shù)來測量接地電阻。這種方法通過在被測接地系統(tǒng)上施加一個已知的電流,然后通過測量接地系統(tǒng)上的電壓降來計算接地電阻。根據(jù)歐姆定律,接地電阻()可以通過以下公式計算:
其中,是測量得到的電壓降,是施加到接地系統(tǒng)上的電流。
接地電阻測量儀器的精度和性能對于確保接地系統(tǒng)的安全性和可靠性非常重要。
