Scott Transformer (Open Delta Transformer)

Scott Transformer (Open Delta Transformer) is a type of connection used to obtain two phase electric power supply (90 deg phase shift) from a three phase source of supply. The Scott connected transformers reduce current unbalance on source side for single phase loads.

Spacial Purpose Transformer

Resin Cast Transformers

We also make and supply Resin Cast Transformers for various applications. In an environment where Dust particle are abundant, or at sea- shore, the chances of getting metals rusty, these transformers are used.

We have supplied these types of Transformers as a solution. Those Transformers are manufactured with fire retardant insulating and self extinguishing materials of Class “F” & “H” (Up to temp. 155°C / 180°C).

Resin Cast Transformers

Hex Phase Transformers

Hex Phase Transformers for parallel combination of two or more rectifier system increases current carrying capability as well as reduces content of harmonics. Generally Low Voltage High Currents requirement is fulfilled with this type transformers. Our Rectifier Transformers are used in applications like, Plating, Battery Charging, Engine Cranking (replacing battery and as DC Source) etc.

Hex Phase Transformers

K Rated Transformers

The K-factor a common industry term for the amount of harmonics produced by a given load is the K-factor. The larger the K-factor, the more harmonics are present. Linear loads, for example, have a K-factor of 1. Transformers may carry a K-factor rating to define the transformer’s ability to withstand the additional heating generated by harmonic currents.

Transfield’s single-phase and three-phase general purpose dry-type ventilated transformers are of the two-winding type, air-cooled, and are available in a wide variety of primary and secondary voltage variants’.

Ultra Isolation Transformers

Spikes generated on switching of electrical utilities (like, Motors, VFDs, UPS Systems, PCs, Rectifiers, Battery Chargers, Lighting Loads, Air Conditioners etc.) in Industrial & Commercial environment can damage Precision Instruments, Micro-processors, or other active electronic devices. During switching of all these, High Voltage (up to 6000 V) & high frequency power line Noises are produced from spikes which interfere with Digital-Electronic equipment causing change in program, erratic behaviour, data corruption, loss of memory etc.

Ultra Isolation Transformers eliminate noises from high frequency and attenuates the spikes to negligible values. This way these protect from such kind of electrical disturbances. Transfield supplies Ultra Isolation Transformers in Single OR Three phase systems up to 100 KVA.
