Nosie
Cut - Of Transformer :
Electrical noises can interfere in the operation of digital electronic
equipments, transistors, Micro processors, sensitive devices, Remote Control
equipments & Telecommunication equipments etc.
KNEL Noise cut of Transformer eliminates all type of electrical noise,
predominantly common mode noises. These transformers are available in
different levels of noise attenuation capabilities.
Design / Construction
 |
Noise cut-of transformers are designed with split winding
construction
and bifilar connections to reduce over all capacitance of the winding. |
|
 |
Use of Faraday's unique box shielding and special techniques totally
block the transfer of electric noise by static charge by way of Proximity
of R.F. noises. |
 |
The core and its magnetic properties are properly selected to exhibit
sufficient leakage inductances to provide possible attenuation of
normal
mode power line noise, consistent with the transfer of fundamental
power
frequency. But all higher frequencies are blocked. |
 |
The use of high content of special grade insulating material and
special
shielding techniques results in common mode attenuation and insulation resistance minimizing
transverse mode noise. |
 |
Due to the better regulation, it does not generate common mode
impedance coupling effect. |
