Elektrik tesisat\u0131nda meydana gelen gerilim de\u011fi\u015fimleri elektronik cihazlara b\u00fcy\u00fck zararlar verir. Bu durum, t\u00fcketiciye maddi olarak olumsuz yans\u0131r. Hi\u00e7 kimse bir buzdolab\u0131 yada televizyon al\u0131rken 1-2 y\u0131l sonra de\u011fi\u015ftiririm niyetiyle almay\u0131p daha uzun y\u0131llar kullanmay\u0131 hedeflemektedir.\"\"<\/strong><\/p>\n

Enerji kayna\u011f\u0131 olan elektrik enerjisini \u00fcreten, ileten ve da\u011f\u0131tan kurulu\u015flar\u0131n g\u00f6revi; t\u00fcketicilerine kesintisiz, ucuz ve kaliteli bir hizmet sunmakt\u0131r. Enerji kalitesi, limit de\u011ferleri uluslararas\u0131 standart otoriteleri taraf\u0131ndan belirlenmi\u015f, \u00f6l\u00e7\u00fclen veya hesaplanan parametre de\u011ferlerinin limitler dahilinde olup olmamas\u0131 durumudur. Parametrelere \u00f6rnek olarak;<\/span><\/p>\n

– Ak\u0131m-gerilim harmonikleri,<\/p>\n

– Sags&swells,<\/p>\n

– Transient,<\/p>\n

– Flicker,<\/p>\n

– N\u00f6tr-toprak aras\u0131 potansiyel fark\u0131,<\/p>\n

Ak\u0131m ve gerilim faz dengesizli\u011fi (3 fazl\u0131 y\u00fckler i\u00e7in),<\/p>\n

– Frekans de\u011fi\u015fimi,<\/p>\n

– K fakt\u00f6r g\u00f6sterilebilir.<\/p>\n

Bu parametrelerden s\u0131k\u00e7a kar\u015f\u0131la\u015f\u0131lan ak\u0131m-gerilim harmonikleri, Sag&swell ve Flicker olaylar\u0131n\u0131 k\u0131saca inceleyelim.<\/p>\n

Harmonik, alternatif ak\u0131m\u0131n tam, d\u00fczg\u00fcn ve temiz bir sin\u00fcs dalga \u015feklinden uzakla\u015fmas\u0131d\u0131r. Harmonikler ne zaman zararl\u0131 olur? E\u011fer trafo\/jenerat\u00f6r g\u00fcc\u00fcn\u00fcn %20\u2019sinden fazlas\u0131, harmonik \"\"ak\u0131mlar\u0131n etkisi alt\u0131nda ise harmonik ak\u0131mlar\u0131 zararl\u0131 olmaya ba\u015flayacakt\u0131r. Harmonik ak\u0131m \u00e7eken y\u00fckler; TV, bilgisayar, floresan armat\u00fcrler, kaynak makinalar\u0131, end\u00fcksiyon ocaklar\u0131, motor h\u0131z kontrol \u00fcr\u00fcnleridir. Harmonikli ak\u0131mlar sistemden fazla ak\u0131m \u00e7ekilmesine ve bu y\u00fczden sistemin verimsizle\u015fmesine neden olur. Ayr\u0131ca fazladan \u00e7ekilen ak\u0131m kablolarda \u0131s\u0131nmaya sebep olur. Gerilim i\u00e7in uluslararas\u0131 standart %5 olarak belirlenmi\u015ftir. Gerilimdeki bozulman\u0131n %5\u2019in \u00fczerine \u00e7\u0131kmas\u0131 elektronik kart ar\u0131zalar\u0131na, makine\/te\u00e7hizat\u0131n hatal\u0131 \u00e7al\u0131\u015fmas\u0131na ve power supply yanmalar\u0131na sebep olur. Motorlarda darbeli \u00e7al\u0131\u015fmalar ve a\u015f\u0131r\u0131 \u0131s\u0131nma motor yata\u011f\u0131 ar\u0131zalar\u0131, ayd\u0131nlatma sisteminde ve pc ekran\u0131nda titre\u015fime sebep olur. Harmonikler bunlara benzer daha bir \u00e7ok problemlere sebep olmaktad\u0131r. Harmoniklerin zararl\u0131 etkilerinden korunman\u0131n en etkili yolu, bu i\u015fin uzman\u0131 bir ki\u015fi veya kurulu\u015fa bir \u00f6l\u00e7\u00fcm yapt\u0131r\u0131p aksakl\u0131klar hakk\u0131nda rapor al\u0131nmas\u0131d\u0131r. Problem yaratacak bir harmonik etki s\u00f6z konusu olursa harmonik filtrasyon yapt\u0131r\u0131lmal\u0131d\u0131r.<\/p>\n

Ani gerilim darbesi-y\u00fckselmesi \u2018Swell\u2019, ani gerilim d\u00fc\u015f\u00fc\u015f\u00fc \u2018Sag\u2019 olarak bilinir. \u2018Sag\u2019 olaylar\u0131 beklenmedik ani y\u00fck art\u0131\u015flar\u0131ndan \u00f6rne\u011fin; k\u0131sa devre, b\u00fcy\u00fck g\u00fc\u00e7l\u00fc motorlar\u0131n start almas\u0131, resistanslar\u0131n devreye girmesi ve ani bir \u015fekilde kaynak empedans\u0131n\u0131n art\u0131\u015f\u0131ndan kaynaklan\u0131r. \u2018Swell\u2019 olaylar\u0131 ise sistemden beklenmedik ani y\u00fck azalmas\u0131, gerilim reg\u00fclat\u00f6rlerinin bozulmas\u0131ndan veya n\u00f6tr iletkenindeki bir problem veya kopmas\u0131ndan kaynaklan\u0131r. Gerilim d\u00fc\u015fmesi olaylar\u0131, da\u011f\u0131t\u0131m sistemlerinde \u00e7ok\u00e7a \"\"kar\u015f\u0131la\u015f\u0131lan bir durumdur. \u00c7o\u011funlukla kayna\u011f\u0131 enerji da\u011f\u0131t\u0131m \u015firketidir. Ayr\u0131ca bina i\u00e7i kablolamada meydana gelen gerilim d\u00fc\u015fmesi olaylar\u0131na sebep olan etmenler, buzdolaplar\u0131 ve klimalar\u0131n devreye girmesidir. Bu durumdan yani elektronik \u00fcr\u00fcnlerdeki yar\u0131iletkenlerin zarar g\u00f6rmesinden ka\u00e7\u0131nman\u0131n en iyi yolu UPS ve statik gerilim reg\u00fclat\u00f6r\u00fc kullanmakt\u0131r.<\/p>\n

Ayd\u0131nlatma sistemlerinde meydana gelen flicker, insanlar ve akkor flamanl\u0131 lambalar\u0131 etkileyen spesifik bir olayd\u0131r. Bu olay gerilimin \u00e7ok k\u0131sa s\u00fcreler i\u00e7inde periyodik olarak y\u00fckselip al\u00e7almas\u0131 ile meydana gelir. Ayd\u0131nlatma sistemlerinde \u0131\u015f\u0131k seviyesindeki s\u00fcrekli de\u011fi\u015fikli\u011fe ve pc ekran\u0131nda titremeye sebep olurken, insanlarda ba\u015fa\u011fr\u0131s\u0131, k\u0131zg\u0131nl\u0131k ve sara n\u00f6betlerine sebep olabilmektedir.<\/p>\n
