CENTRADO transformer can handle dielectric test to high voltage 50Hz/60Hz and impulse voltage according to IEC Standard and Indonesia Standard (SPLN & SLI).
Primary Voltage Compatibility with voltage distribution system in Indonesia, i.e : 6 KV, 12 KV, 20KV and 24 KV. Primary voltage tapping had been done with comutator (Tap-Changer) with empty load on primary side. CENTRADO also serving special inquiry for other high voltage transformer according to costumer needs. Tapping system is moved to appropriate +4%, +2,5% atau 5%. For transformer with capacity above 100 KVA can be made with 2 primary voltage comutator switch / construction voltage movement outside the tank makes usage with double function easier, can be locked for safety.
Secondary Voltage Secondary voltage side on empty load can be made 133 V/231 V (B1) and 231 V / 400 V (B2) or can be together with condition : on 133 V / 231 V only 75% and on 231 V / 400 V, so the power is : 100% from it’s normal power.
Construction A. Transformer Core Transformer cores made from Grain Oriented Silicon Steel M4 0,27 mm designed to guarantee the mechanic power, reduce vibration and noises with low iron losses. B. Coils Coil made by high constructivity copper, coil on high voltage side made by enamel isolated copper wire, and on low voltage side made by paper isolated wire. Note : If there is any special inquiry for higher isolation class, basic commodity will be provided. * Cores and coils will then dry out with oven until is 2000 Mega Ohm. C. Terminal High voltage terminal using isolator porcelain or elastimold Synthetic Resin. Low voltage terminal using isolation porcelain with current above 1000A with syntehtic resin isolated copper. D. Tank Made by zinc plated steel ( Electrogalvanized Zin Coated Steel ) or Mild Steel Plate. Construction designed with waterproff and airtight. E. Transfomer Packing Transformer packing made by rubber that can hold high temperature and also has a good oil resistant.

F. Painting Before painting process, has to vanish the oil and rust on steel sheet surface. Continue with last painting then heated on some temperature to gets a perfect result.
G. OIL Minyak trafo mempunyai fungsi ganda yaitu sebagai isolasi dan pendingin. Sesuai standar PLN, olie trafo yang digunakan adalah : SHELL DIALA B “ atau sejenisnya.
Vector group Generally for 25 KVA until160 KVA, vector group that used is : YZN-11, YZN-5. And for above 200 KVA , vektor group that used is : DYN-5 atau DYN-11.
