• Distribution Transformers

Industrial, Substation & Distribution Tfr. Upto 10 MVA, Upto 33kV, ONAN A poly phase transformer design is presented in which transformer output pores are accurately constructed in both voltage magnitude and relative phase angle. The design incorporates both main and auxiliary transformers that are used in unison to produce the accurately constructed phases. The main transformer permits rough phase adjustment to be made with the auxiliary transform permitting phase fine tuning. Such a design is particularly suitable in transformer approaches that require output phases that are of a number not evenly divisible by three.

• Reactor Transformers

Air cored series & Shunt Reactor, Upto 2 MVA , Upto 33Kv, ONAN / AN A variable transformer, reactor having a core combining at least two complete core elements with a common yoke; primary winding divided into two independently fed sets of phase coils wound in opposite direction, arranged on symmetrical legs of core elements and separated by the common yoke; secondary winding with each phase coil divided into two wound in opposite direction portions carried by symmetrical core legs, adjacent to the primary coils and separated by common yoke. The secondary short-circuited reactor winding is reduced to at least one close loop member with loop portions separated by the common yoke. The single, poly phase apparatus has at least one primary coil per set that includes a controllable device in circuit relation therewith to enable control of one primary coil relative to the other, either in current magnitude or in current phase shift. The controllable device being either a silicon control rectifier or transistor.

• Dry Transformers

Industrial, Substation & Distribution purpose Manufacturing range Upto 2MVA 22 KV naturally air cooled. A dry type transformer has an iron core, vacuum pressure resin impregnated high voltage windings and low voltage windings . The low voltage winding is constructed with conductors. Dupond nomex insulating material includes an apparatus to secure the windings in place during a vacuum and pressure resin impregnation process. The result is a coil that exhibits high short circuit protection due to the tightly bond conductors comparable to completely resin encased molded transformers at a substantially reduced cost.
