<\/i><\/i>OBSERVE MAINTENANCE INTERVALS<\/a><\/h3>\n
\n

Make sure that your on-load tap-chang\u00aders are under\u00adgo\u00ading main\u00adte\u00adnance at the appro\u00adpri\u00adate inter\u00advals. The date of a next main\u00adte\u00adnance appoint\u00adment will depend on how long it has been in use or how many switch\u00ading oper\u00ada\u00adtions it has per\u00adformed. As an exam\u00adple, some tap-chang\u00ader types may be due for main\u00adte\u00adnance after sev\u00aden years or 70,000 switch\u00ading oper\u00ada\u00adtions, which\u00adever comes first.<\/p>\n<\/div>\n<\/div>\n

\n

<\/i><\/i>USE QUALIFIED STAFF<\/a><\/h3>\n
\n

Per\u00adform\u00ading main\u00adte\u00adnance on a trans\u00adformer is a job for an expert\u2014not just any tech\u00adni\u00adcian will be famil\u00adiar with the spe\u00adcif\u00adic demands that trans\u00adform\u00aders and tap chang\u00aders pose. Hav\u00ading main\u00adte\u00adnance per\u00adformed by qual\u00adi\u00adfied staff will make it pos\u00adsi\u00adble to iden\u00adti\u00adfy any irreg\u00adu\u00adlar\u00adi\u00adties in oper\u00ada\u00adtion ear\u00adly on.<\/p>\n<\/div>\n<\/div>\n

\n

<\/i><\/i>CHECK THE OIL<\/a><\/h3>\n
\n

Check the oil at least once a year. The state of the oil can shed some light on the fit\u00adness of a transformer\u2014just like a blood test can give a doc\u00adtor insights into a patient\u2019s health. For exam\u00adple, low water con\u00adtent, high sur\u00adface ten\u00adsion, a high lev\u00adel of dielec\u00adtric strength, and a low pow\u00ader fac\u00adtor are all indi\u00adca\u00adtors of good oil qual\u00adi\u00adty.<\/p>\n<\/div>\n<\/div>\n

\n

<\/i><\/i>PERFORM A DGA<\/a><\/h3>\n
\n

An even more in-depth analy\u00adsis involves an addi\u00adtion\u00adal inves\u00adti\u00adga\u00adtion of the gas\u00ades. We rec\u00adom\u00admend per\u00adform\u00ading such a dis\u00adsolved gas and oil Analy\u00adsis (DGA) once a year. This involves check\u00ading the ratio of dis\u00adsolved gas\u00ades in the oil. Each of the gas\u00ades is gen\u00ader\u00adat\u00aded in the trans\u00adformer by a cer\u00adtain state or cer\u00adtain con\u00addi\u00adtions. Once the analy\u00adsis is com\u00adplete, we can tell whether the trans\u00adformer is in good con\u00addi\u00adtion.<\/p>\n<\/div>\n<\/div>\n

\n

<\/i><\/i>CHECK THE OIL LEVEL<\/a><\/h3>\n
\n

Each oil cham\u00adber must have enough oil in it, so it is impor\u00adtant to check the lev\u00adels. This includes the main tank, the on-load tap-chang\u00ader con\u00adtain\u00ader, and the bush\u00adings. Check\u00ading oil lev\u00adels is impor\u00adtant because the oil acts as an insu\u00adlat\u00ading mate\u00adr\u00adi\u00adal, coolant, and lubri\u00adcant all at the same time.<\/p>\n<\/div>\n<\/div>\n

\n

<\/i><\/i>CHECK THE DEHUMIDIFICATION<\/a><\/h3>\n
\n

Check the dehu\u00admid\u00adi\u00adfi\u00adca\u00adtion unit reg\u00adu\u00adlar\u00adly to ensure that no imper\u00admis\u00adsi\u00adble mois\u00adture is enter\u00ading the oil expan\u00adsion ves\u00adsel from the out\u00adside, because mois\u00adture in the oil will short\u00aden the transformer\u2019s ser\u00advice life. Have an expert check whether the device is work\u00ading reli\u00adably. It may be that the sil\u00adi\u00adca gel\u2014which is vital for remov\u00ading water\u2014needs to be replaced.<\/p>\n<\/div>\n<\/div>\n

\n

<\/i><\/i>HAVE REGULAR INSPECTION CARRIED OUT<\/a><\/h3>\n
\n

Reg\u00adu\u00adlar inspec\u00adtions are extreme\u00adly impor\u00adtant. Our spe\u00adcial\u00adists check all of the installed components\u2014including bush\u00adings, fans, dis\u00adplays, valves, motor-dri\u00adve units, and con\u00adtrol cabinets\u2014for issues such as leaks or cor\u00adro\u00adsion in order to detect them ear\u00adly on. Func\u00adtion checks on pro\u00adtec\u00adtive devices allow us to ensure that the trans\u00adformer will switch off imme\u00addi\u00adate\u00adly in the event of a fault.<\/p>\n<\/div>\n<\/div>\n<\/div>\n
