Ultra / Super Isolation Transformers effective for Isolating sensitive equipment’s form Line Voltage transients, spikes & D.C. leakage etc. They are specially designed for sensitive critical equipment’s like computers & peripherals, medical instrumentation, digital communication systems, CNC Machines etc. and stopping such disturbances generated by the noisy equipment load from being injected into the power line. Multiple shielding techniques employed reduce the inter winding capacitance to below 0.005 Picofarad and increase D.C. Isolation to over 1000 Megaohms.Technically any transformers that gave no direct current path between it’s primary & secondary windings provides Isolation. Other commonly used transformers even if they have separate primary & secondary winding are intended to convert the input voltage to a more useful level. Even though both are separately wound transformers, they are substantially different w.r.t. construction, specification & performance
characteristics.
In shielded transformer, Four Low impedance path exists for noises to pass to secondary & vice versa.
•The High Value of Coupling Capacitance.
•The Maximum Linkage of magnetic field.
•The Leakage Current.
•Static Transfer of Electric Noises.
