Isolation Transformer

Isolation Transformer

We are specialized In Isolation, Ultra Isolation and K-Rated transformers. We Design our Isolation Transformers in such a way to meet all the purpose of an Isolation Transformer. We are supplying our Isolation Transformers serving with lot of CNC Manufacturers, CNC Machine Shops, UPS Manufacturers, Imported UPS dealers, etc.

Isolation Transformer

An Isolation Transformer is a device which is use to decouple two circuit, the load to the Isolation Transformer and to the Input supply, Isolation Transformer suppress electrical noise which occurs in transmission line. An Isolation Transformer blocks transmission of DC signal from one Circuit to other and allow ac signal to transmit. It also prevent interference cost by ground looping. Isolation Transformers are constructed with two isolated Faraday shields between the primary and secondary windings. The use of two shields in the construction of the isolation transformer diverts high frequency noise, which would they occur The two shields provide more effective isolation of the primary and secondary circuits and also isolation to their grounds.

Ultra Isolation

Ultra Isolation Transformers are used where high attenuation level is required like Communication Systems, Wireless Station, Sensitive Medical Equipments etc., These special type transformers are manufactured by splitting primary and secondary coils results reduction in coupling Capacities in transformer Circuit

COMMON – MODE NOISE
This noise appears between both sides of power line and ground. These High Frequencies noise occurs between ground and conductor.

TRANSVERSE – MODE
Transverse – Mode noise is much more difficult to eliminate than common-mode noise. These High magnitudes noise occurs between two conductors due to switching action of equipments

Advantages of line Isolation Transformers

  • Very high noise attenuation capacity
  • Reduced coupling capacitance.
  • Lesser leakage current
  • Suitable for higher harmonic loads.
  • Core will not saturate even if the applied voltage is high.

K-RATED TRANSFORMERS

K factor is value used to determine how much harmonic current a transformer can withstand without exceeding its maximum temperature level. Huge numbers of single Phase loads like computers also create nonlinear harmonics. A standard Transformers can not handle the harmonics due to non-linear loads. When harmonics enter in to the transformer the core gets saturate as result it produced lot of heat causes the failure of transformer.

k-rated transformers are Specially designed to with stand this non-linear harmonics. K-rateing differs according to the harmonic levels like K-1, K-4, K-7, K-13, K-20, etc.,

We are designing our K-Rated Transformers according to its guide lines and Specification given by ANSI C57 standard NFPA-70, UL 1449 and UL 1567. We use high grade CRGO laminations for our K-Rated Transformers. Our K-Rated Transformers are Class-H which will with stand 180 continuously. We use notching type lamination for our K-Rated transformers, because of that our Transformer core will not saturate even in high Voltage.

Non-liners          Load K-rating
THD < 5%             K-1
THD < 35%           K-4
THD < 50%           K-7
THD < 75%           K-13
THD < 100%         K-20

We also manufacture Aluminum wound Transformers with the same quality to minimize the initial investments Our design will support to maintain the same performance of Copper Transformers in Aluminum Transformers also.

FEATURES OF CLEAN LINE K-RATED TRANSFORMER

  • Copper wound construction mainly strip in parallel to reduce skin effect.
  • Ultimate design.
  • Notching type of lamination (CRGO) which can prevent core saturation due to. non-liner harmonics.
  • 10 to 15% over voltage also the core will not saturate.
  • Working with very high flux density.
  • Compact Size
  • Class H insulation, High thermal withstanding capacity.
  • 100% liner harmonic attenuation and more than 75% on non-linear Ida, Tapping in the primary side of the transformers.
  • Attenuate triple line harmonics from the line.
  • Multi shielded transformer where you will get higher common mode noise attenuation.
  • Excellent transverse mode noise attention.
  • Solve 88% of tropical power disturbance.
  • Low temperature raise.
