Oil Cooled Transformer

Model HV-EXP5725
Oil Cooled Transformer Copper coils are wounded with perfect tappings on the both secondary and primary sides Air cooled transformer made up of grade laminated core of silicon stamping used. Terminals insulated for both primary and secondary with properly marked Facility of outlets and inlets with stop-cocks For transformer cooling perfect fins are equipped in oil cooling type MS powder box in housed transformer to prevent from rust For the high insulation strength, primary and secondary coils are impregnated in vacuum 1KVA/ 2KVA/ 3KVA/5KVA upto15kva with voltage ratio 415/415v or 415/215v or as per requirements. Perfect type of oil/air cooled type  of transformer basically used for various experiments: In order to known its efficiency and parameters of its same circuits sumpner back to back tests are  performed In order to known its efficiency and parameters of its same circuits QC and SC tests are conducted on 3 phase transformers. To study the performance of 3-phase transformer for its various connections, i.e. delta/ delta-star star-star /star-and delta-delta and find the magnitude of 3rd harmonic current.
