Kazhinji, mutsara wese weUHV mutsara unodzivirirwa newaya yepasi, kana tambo yepasi uye OPGW optical tambo, ine zvimwe zvinokonzeresa kudzivirira mheni kune UHV kutapurirana tambo.Iwo chaiwo matanho ekudzivirira mheni ndeaya anotevera:
GDCR2000G Earth Resistance Tester
1. Deredza kukosha kwekupikisa kwepasi.Kunyangwe kupikisa kwepasi kwakanaka kana kwete kuchakanganisa zvakananga mwero wekudzivirira mheni wemutsara uchirova mbesa.Iva nechokwadi chekubatana kwakavimbika pakati peshongwe uye pasi pasi conductor.Mukugadzirisa kwezuva nezuva, wedzera patrol uye kunyatsotevera nguva ye-pre-test yemutsara kuti uone kupikisa kwepasi.Izvo zvinodiwawo munzvimbo dzakakosha.Kupfupisa pre-test nguva.Mumitsetse yekufambisa magetsi mumakomo, mamwe mapango ari pamusoro nepamusoro pegomo.Matanda aya akaenzana nemapango akakwirira uye anofanirwa kubatwa seshongwe dzekuwedzera.Vanowanzova nzvimbo dzisina njodzi dzehupfumi hunodonha, uye dzinofanirwa kutarisisa kudzikisira kudzika kwepasi.Nokudaro, zvinokurudzirwa kushandisa HV HIPOT GDCR2000G Earth Resistance Tester kuyera kukosha kwekudzivirira kwepasi kweshongwe nguva dzose.Inokodzera pasi inotungamira yeakasiyana maumbirwo (yakatenderera simbi, flat simbi uye angle simbi).Clamp-on ground resistance tester inoshandiswa zvakanyanya mukuyerwa kwepasi kwesimba remagetsi, telecommunications, meteorology, munda wemafuta, kuvaka uye zvigadzirwa zvemagetsi zvemaindasitiri.
2. Gadzira tambo yepasi yekubatanidza.Gadzirisa tambo yekubatanidza pasi (kana pedyo) waya, iyo inogona kuita basa rekuvhara uye kubatanidza kana shongwe yarohwa nemheni, uye ipapo voltage inotakurwa neshongwe insulator inovandudza mwero wekudzivirira mheni yemutsara.
3. Zviri nani kuwedzera nhamba kana kureba kwezvidziviriro kuti uwedzere simba rekugadzirisa kwezvidziviriro paunenge uchivimbisa kutsauka kwemhepo yetambo ye insulator.
4. Isa danda remheni rinodzoreka pamusoro peshongwe yegomo kana musoro weshongwe munzvimbo dzinorova mheni kakawanda.
5. Kuti udzivirire simba frequency arc inopisa uye inotungamira mari inokonzerwa nemheni inorova, kukurumidza relay kudzivirira kunofanira kushandiswa zvakanyanya sezvinobvira kupfupisa nguva yerwendo.Kurova kwakawanda kwemheni ndeye-phase-phase flashovers, saka imwe-phase otomatiki kuvharika kunofanirwa kushandiswa zvakanyanya sezvinobvira.
6. Mutsara mutsva wekutumira unoshandura chimiro cheshongwe yemusoro panguva yeshongwe dhizaini nhanho, kuitira kudzikisa kona yekudzivirira yewaya pasi kune conductor.Iko kushandisa kona yekudzivirira isina kunaka munzvimbo dzakakosha dzekudzivirira mheni kuderedza chiyero chekudzivirira mheni.
7. Paunosarudza nzira yekutanga kugadzirisa mutsara wepamusoro, dzivisa nzvimbo dzemaguta dzinowanzoita kutinhira nemheni.
