1. Khetha i-transformer ngokuya ngesimo somthwalo:

1. Uma kunenombolo enkulu yemithwalo eyisisekelo noma yesibili, ama-transformer amabili noma ngaphezulu kufanele afakwe. Lapho noma iyiphi enye ye-transformer inqanyuliwe, amandla ama-transformers asele angahlangabezana nokusetshenziswa kwamandla kwemithwalo eyisisekelo neyesibili. Imithwalo eyisisekelo neyesibili kufanele igxilwe ngangokunokwenzeka futhi akufanele ihlakazeke kakhulu.

2. Uma umthamo womthwalo wesizini mkhulu, kufanele kufakwe i-transformer ekhethekile. Njengomthwalo weziqandisi zomoya kanye nemithwalo yokushisa kagesi yokufudumeza ezakhiweni ezinkulu zomphakathi.

3. Uma umthwalo ogxilile umkhulu, i-transformer ekhethekile kufanele ifakwe. Okufana nemishini emikhulu yokushisisa, imishini emikhulu ye-X-ray, izithando zomlilo zikagesi ze-arc, njll.

4. Uma umthwalo wokukhanyisa mkhulu noma amandla nokukhanyisa kusetshenziswa i-transformer eyabiwe, ethinta kakhulu izinga lokukhanyisa kanye nempilo ye-bulb, i-transformer yokukhanyisa ekhethekile ingafakwa.

2. Khetha isiguquli ngokuya ngendawo yokusetshenziswa:

1. Ngaphansi kwezimo ezijwayelekile ezimaphakathi, ama-transformer acwiliswe uwoyela noma ama-transformers ohlobo olomile angakhethwa kuye ngokwesimo, njengeziteshi ezizimele noma ezinamathiselwe ezinkampanini zezimboni nezezimayini, ezolimo, iziteshi ezizimele ezindaweni zokuhlala, njll. Ama-transformer atholakalayo yi-S8 , S9, S10, SC(B)9, SC(B)10, njll.

2. Emabhilidini amakhulu anezitezi eziningi noma eziphakeme, ama-transformer angashi noma amelana nelangabi kufanele akhethwe, njenge-SC (B) 9, SC (B) 10, SCZ (B) 9, SCZ (B) 10. , njll.

3. Ezindaweni lapho amagesi anothuli noma abolayo athinta kabi ukusebenza okuphephile kwama-transformer, kufanele kukhethwe ama-transformer avaliwe noma avaliwe, njenge-BS 9, S9 – , S10- , SH12-M, njll.

4. Imishini yokusabalalisa amandla aphezulu naphansi ngaphandle kwamafutha avuthayo kanye nama-transformer okusabalalisa angagxili kawoyela angafakwa ekamelweni elifanayo. Ngalesi sikhathi, i-transformer kufanele ifakwe igobolondo lokuvikela le-IP2X ukuze kuphephe.
