Chongqing Kailian Yongrun Industrial Co.,Ltd.
Transformer uses oil as coolant and insulator. Gases are formed within the transformer oil due to natural aging, faults from oxidation, vaporization, oil breakdown, electrolytic action or insulation decomposition. Because the transformer oil bathes each internal component, dissolved gases in the transformer oil contain lots of diagnostic information. Meanwhile, the transformer is very expensive to be replaced, so monitoring these gases is very important to know the current quality of transformer or even when the transformer should be removed from service before failure. Presence of each gas composition and its concentration indicates possible failure of transformer.

6300A -
Eltel Industries
The Model 2509 Instrument Current Transformer is a 6300 A ampere CT designed for precision measurement of AC current or for Instrument Current Transformer calibration applications. The CT can be installed on a bus bar or it can be used with a primary conductor consisting of number of turns. The 6300 CT is designed with a tapped primary & a tapped secondary winding, thus providing a large number of ratios over a range of 5 to 6300 amperes.

Osborne Transformer Corp.
Osborne high impedance transformers are used to step-up, step-down and isolate voltages in single phase and three phase circuits. A properly designed high impedance transformer can be used an an equivalent to an isolation transformer connected in series with an inductor. The high impedance characteristic may be employed as a current limiting feature in both the primary and secondary circuity.
