Iyini imiphumela yesisekelo esingesihle?

Isamba sokumelana nokuphansi komzimba ophansi noma umzimba ophansi wemvelo kanye nokumelana nocingo oluphansi kubizwa ngokuthi ukumelana nokuphansi kwensiza ephansi.Inani lokumelana nendawo eliphansi lilingana nenani lamandla kagesi wedivayisi ephansi eya phansi namanje agelezela emhlabeni ngomzimba ophansi.Ukumelana okuphansi okutholwe yi-inrush current egeleza emhlabeni ngomzimba ophansi kubizwa ngokuthi ukumelana ne-impulse grounding;ukumelana okutholwe imvamisa yamandla wamanje ageleza emhlabeni ngomzimba ophansi kubizwa ngokuthi ukumelana ne-ground frequency yamandla.

Uma kwenzeka iphutha eliphansi empahleni yamandla, umehluko ongaba khona phakathi kwengxenye esekelwe phansi nendawo engaba yiziro yomhlaba ibizwa ngokuthi i-voltage yedivayisi yokumisa phansi noma amandla edivayisi yokubeka phansi.
Imiphumela engaba khona yesisekelo esingesihle
1. Izintambo eziphukile kanye nokuxhumeka okubonakalayo kocingo lwaphansi kungabangela kalula ukuthi intambo yaphansi ishiswe i-current enkulu noma ukumelana nokusekela phansi okuphrintiwe kukhulu, okuholela ekubeni khona kwamandla aphansi aphansi.Ukuhlolwa kwekhwalithi kokubili akwenzi iluphu, ukuze amandla aphezulu ohlangothi lwe-voltage ephezulu ye-transformer angeke asekelwe ngokuqondile.Ngaphezu kwalokho, izisebenzi zesondlo ziyajuluka kakhulu ngemva kokuphuma emsebenzini, ukumelana nomzimba womuntu kuyancipha, futhi amandla ku-transformer asheshe aholele emhlabathini ngokusebenzisa umzimba womuntu.Uma kungumthamo obulalayo, kuzodala ukulimala noma ukufa kwabasebenzi bezokulungisa.
2. Uma ulungisa ama-transformers noma imigqa yamandla aphezulu, akukho cingo lokumisa olufakwe ohlangothini lwesibili.Uma umshini wokushisela noma ezinye izinto zokukhiqiza amandla eselula zisetshenziswa ohlangothini lwesibili, kulula ukubangela ukuthi uhlangothi lwesibili lubuyisele ugesi futhi lwandise i-voltage efakwe ohlangothini oluyinhloko lwe-transformer.Ukwanda kwamanje;uma othile esebenza ku-transformer, i-voltage yokubuya iphezulu, yamanje inkulu, futhi kulula ukubangela ukulimala kubasebenzi.
