3 3 ENTRDO trnsformer n hndle dieletri test to high voltge 5Hz/6Hz nd impulse voltge ording to IE Stndrd nd Indonesi Stndrd (SPLN & SLI). Primry Voltge omptiility with voltge distriution system in Indonesi, i.e : 6 KV, 12 KV, 2KV nd 24 KV. Primry voltge tpping hd een done with omuttor (Tp-hnger) with empty lod on primry side. ENTRDO lso serving speil inquiry for other high voltge trnsformer ording to ostumer needs. Tpping system is moved to pproprite +4%, +2,5% tu 5%. For trnsformer with pity ove 1 KV n e mde with 2 primry voltge omuttor swith / onstrution voltge movement outside the tnk mkes usge with doule funtion esier, n e loked for sfety. Seondry Voltge Seondry voltge side on empty lod n e mde 133 V/231 V (1) nd 231 V / 4 V (2) or n e together with ondition : on 133 V / 231 V only 75% nd on 231 V / 4 V, so the power is : 1% from it s norml power. onstrution. Trnsformer ore Trnsformer ores mde from Grin Oriented Silion Steel M4,27 mm designed to gurntee the mehni power, redue virtion nd noises with low iron losses.. oils oil mde y high onstrutivity opper, oil on high voltge side mde y enmel isolted opper wire, nd on low voltge side mde y pper isolted wire. Note : If there is ny speil inquiry for higher isoltion lss, si ommodity will e provided. * ores nd oils will then dry out with oven until is 2 Meg Ohm.. Terminl High voltge terminl using isoltor porelin or elstimold Syntheti Resin. Low voltge terminl using isoltion porelin with urrent ove 1 with syntehti resin isolted opper. D. Tnk Mde y zin plted steel ( Eletroglvnized Zin oted Steel ) or Mild Steel Plte. onstrution designed with wterproff nd irtight. E. Trnsfomer Pking Trnsformer pking mde y ruer tht n hold high temperture nd lso hs good oil resistnt. 3 Design Mnufturing Instlltion Servie
