Measure primary inductance
WebThis is usually a higher value of capacitance than the primary capacitance, and is a function of the insulation distance between primary and secondary. Resonant Frequency and Inductances It can be seen from the open-circuit impedance measurement in Fig. 4 that the resonant frequency of the transformer is quite low, less than 2 MHz for a 100 kHz ... WebTo minimize leakage inductance, the primary winding should be wound on a long bobbin, or tube, with the secondary wound as close as possible, using a minimum of insulation. …

WebThe open-circuit measurement gives information on the primary resistance, magnetizing inductance, and capacitance (via the resonant frequency seen at about 1 MHz). The … WebInductance is defined as the ratio of the induced voltage to the rate of change of current causing it. It is a proportionality factor that depends on the geometry of circuit conductors and the magnetic permeability of nearby materials. [1] An electronic component designed to add inductance to a circuit is called an inductor.
