VOLTAGE TRANSFORMER
Dyco Electronics, Inc. is proud to offer a line of high voltage transformer supplies for use with static neutralizing equipment. Within a magnetic component for electrical components such as a voltage transformer there is a capacitive effect that occurs between turns, between layers, between windings (if there is more than one), between winding and core and between winding and encapsulant. This os what is known as distributed Capacitance (Cd).		voltage transformer toroidal transformer current transformer flyback transformer
A variable voltage transformer is an efficient method to alter voltage. This is really important if you require more flexibility in changing the ratio between the primary and secondary coils. A variable voltage transformer is quite simple to use, and automatic adjustment controls are available to keep a voltage output regulated. The degree of voltage fluctuation you have depends upon the variable voltage transformer that is used. Leakage flux causes a self inductance in a voltage transformer. Typically, it is undesirable but it also unavoidable. It can be minimized through various winding techniques but minimizing leakage inductance has the unfortunate effect of increasing another parasitic component, capacitance. Leakage inductance is usually measured by shorting a secondary winding and measuring the value of series inductance across the primary winding.	A flux that does not link both windings is called leakage flux and has the effect of adding an inductance that produces a voltage transformer drop when current is present. Leakage is affected by the shape of the core and by the arrangement of the windings.
