Kusiyana Kwa Njira Zoyesera Pakati pa Insulation Resistance Tester Ndi Ground Resistance Tester
(1) Njira Yoyesera ya Insulation Resistance Tester
Insulation Resistance Tester Ndi Kuyesa Kuchuluka Kwa Insulation Pakati Pa Magawo, Zigawo Ndi Malo Osalowerera Ndale Ndi Zingwe.Mayeso Okwera Kwambiri, Ndibwino Kuchita Kwa Insulation.Kukaniza kwa Insulation Kutha Kuyesedwa ndi UMG2672 Electronic Megohmmeter.
(2) Njira Yoyesera Ya Grounding Resistance Tester
Grounding Resistance Tester Ndi Chida Champhamvu Chomwe Chimazindikira Ngati Kukaniza Kuyika Ndikoyenera.Njira Yoyesera Ya Grounding Resistance Tester Ndi Yoti Zipangizo Zamagetsi Zimalumikizidwa Ndi Mphamvu Zomwezo Ndi Dziko Lapansi, Ndipo Ndi Kuyandikira Kwa Waya Wa Reaction Kapena Conductor Pansi Padziko Lapansi.Mtengo Woyezedwa Ndi Grounding Resistance Tester Ndi Njira Yogwira Ntchito Yotsimikizira Chitetezo Chaumwini.Mutha Kusankha DER2571 Digital Grounding Resistance Tester Yopangidwa Ndi WeiA Power.
Chachinayi, Kusiyana kwa Mfundo Pakati pa Insulation Resistance Tester Ndi Ground Resistance Tester
(1) Mfundo ya Insulation Resistance Tester
Pamene Insulation Resistance Tester Imagwiritsidwa Ntchito Kuyeza Kukaniza Kwa Insulation, The DC Voltage U Imagwiritsidwa Ntchito Kumangirira.Panthawiyi, Kusintha Kwamakono Kumasintha ndi Nthawi, Ndipo Pomaliza Kumakhala Pamtengo Wokhazikika.
Nthawi zambiri, Pakalipano Wa Insulation Resistance Tester Ndi Chiwerengero Cha Kuthekera Kwaposachedwa, Kuyamwitsa Panopa Ndi Mayendedwe Apano.Capacitive Current Ic, Kuthamanga Kwake Kuthamanga Ndikothamanga Kwambiri;Mayamwidwe Panopa Iaδc, Imawola Pang'onopang'ono Kuposa Capacitive Panopa;Conduction Current Inp, Imakhazikika Pakanthawi kochepa.
Pakuyesa Kugwiritsa Ntchito Insulation Resistance Tester, Ngati Kuyikirako Kulibe Chinyezi Ndipo Pamwamba Pamakhala Paukhondo, Zida Zaposachedwa Za Ic Ndi Iaδc Zidzawola Mwamsanga Kufikira Zero, Kungotsala Kachulukidwe Kakang'ono Kamene Kakachitikako, Chifukwa Kukaniza Kwa Insulation Ndikosiyana. Molingana ndi Kuzungulira Panopa, Kukaniza Kwa Insulation Kudzakwera Mwamsanga Ndi Kukhazikika Pamtengo Waukulu.Mosiyana ndi zimenezi, Ngati Kusungunula Kuli Kwachinyezi, Kuyendetsa Pano Kumakula Kwambiri, Ngakhale Kuthamanga Kwambiri Kuposa Mtengo Woyamba Wa Mayamwidwe Pakalipano Iaδc, Gawo Lakanthawi Limeneli Lachepetsedwa Kwambiri, Ndipo Mtengo Wotsutsana ndi Insulation Ndiwotsika Kwambiri, Ndipo Imasintha Kwambiri Ndi Nthawi.Micro.
Chifukwa chake, pakuyesa kwa Insulation Resistance Tester, Chinyezi cha Insulation Nthawi zambiri chimaweruzidwa ndi Mayamwidwe Ratio.Pamene Mayamwidwe Ratio Ndi Wamkulu Kuposa 1.3, Zimasonyeza Kuti Insulation Ndi Yabwino Kwambiri.Ngati Mayamwidwe Ratio Ali Pafupi ndi 1, Zimasonyeza Kuti Insulation Ndi Yonyowa.
(2) Mfundo ya Grounding Resistance Tester
Grounding Resistance Tester Amatchedwanso Grounding Resistance Measument Chida, Grounding Shaker.Mfundo Yoyesera Yakuyesa Kukaniza Pansi Ndi Kupeza Mtengo Wotsutsa Pansi "Rx" Kudzera mu AC Constant "I" Pakati pa Ground Electrode "E" Ndi Power Supply Electrode "H(C)" Yachinthu Choyesedwa, Ndipo Kutsikira Kumapezeka Kusiyana Kwamalo "V" Pakati pa Electrode "E" Ndi Electrode Yoyezera "S(P)".
