Isolation Transformer

We are offering various sorts of Furnace Transformers which are developed from the best available technology. Some advanced characteristics include sufficient reliability, enough short circuit tolerance, advanced coil drying technique, long life on-load tap changer and coil structure necessary for both low voltage and heavy current. These are available in various sizes and designs. Some more specifications include:

 

• They are used for tempering purpose

• These are oil/Air Cooled Transformed Designed with duty cycle rating 100%

• Multiple ratio output for changing resistance

• May be Single Phase, Two Phase or Three Phase

 

These are of two types:

 

(I) Salt Bath Furnace Transformer Capacity= 12V - 10KVA to 500 KVA 24V - 10KVA to 500 KVA

 

(II) Rotary Furnace Transformer Capacity= 70V to 120V Output Neutral to Phase

Isolation Transformer often has symmetrical winding which is used to decouple 2 circuits. It incorporates a full metallic shielding (copper /aluminum) between primary & secondary winding

Isolation Transformers are being used to protect electronic & sensitive creative equipment such computer & peripherals medical instruments, digital machines & CNC M/C from the Excessive line voltage transient, spikes/surges which produced in the system. Apart from this, isolation Transformer also obstructs those disturbances that are generated by the noisy equipment from being injected into the power line i.e. it filters common mode noise usually an attenuation of approx. 30 db.

In Shielded transformer, 4 low impedance path Exist for noises to pass to secondary & vice versa. These paths are:

 

• High value of coupling capacitance.
• Maximum leakage of magnetic field.
• Leakage current
• Static transformers of electric noise.

The multiple shielding techniques employed in isolation Transformers reduce the inter winding capacitance below to 0.005 Pico farad & increase D.C isolation to over 1000 M ohms.


Application of Isolation Transformer

• Protection of microprocessor based Machines from Damage & data loss
• Where ground of equipment cannot be earthen
• When no current leakage is permitted in equipment
• When protection is needed against high frequency line losses & strong surges.
