Wadanne matsaloli ya kamata a kula da su wajen auna ma'aunin ma'aunin polarization

Sharuɗɗa don auna ma'aunin sha

Ba za a iya auna ma'aunin sha da ƙididdiga na polarization na mai canzawa tare da nau'in ƙarfin lantarki na 10kv da ƙarfin wutar lantarki na cibiyar sadarwa da ke ƙasa 4000kvA ba.

Lokacin da matakin ƙarfin lantarki mai canzawa ya kasance 220kv ko sama kuma ƙarfin yana sama da 120MVA, yakamata a yi amfani da ma'aunin juriya na 5000V don auna ƙimar sha.Matsakaicin sha bai kamata ya zama ƙasa da 1.5 a zafin jiki ba.Lokacin da ƙimar juriyar rufewa ta fi 10000MΩ a R60min, ba a buƙatar fihirisar polarization.

Ya kamata a kula da waɗannan matsalolin masu zuwa wajen auna ma'aunin ma'aunin ƙima

(1) Kowane ma'auni ya kamata ya zaɓi ma'aunin juriya na ƙarfin lantarki iri ɗaya, masana'antun daban-daban ba su da tasiri;

(2) A lokacin aunawa, ya kamata a zaɓi layin fitarwa mai ƙarfi a matsayin layin kariya mai ƙarfi na musamman, kuma layin fitarwa na L da N ba za a iya musanya shi ba, layin gwajin bai kamata ya yi rauni ba kuma a dakatar da shi gwargwadon yiwuwa;

(3) Don hana ragowar cajin yin tasiri ga sakamakon gwajin, abin da aka gwada ya kamata a fitar da shi gabaɗaya kafin gwajin;

(4) Kafin gwajin, cire wayar gwajin, goge haɗin gwajin da tsabta kuma tabbatar da cewa ƙasa ta dogara;

(5) Don hana tasirin yatsan ruwa na yanzu kamar yadda zai yiwu a cikin zafi na iska shine ƙaramin gwaji, lokacin da ya cancanta don haɗa zoben garkuwa;

Abubuwan da ke sama su ne matsalolin da ya kamata a kula da su yayin auna ma'aunin ma'auni na polarization.Wajibi ne a kula da zaɓin ƙarfin lantarki don kayan aikin wutar lantarki.Ya kamata ya kasance daidai da ƙayyadaddun gwaji.
