Measurements include Z, [theta], L, C, R (AC and DC), Q, D, turns ratio N, leakage inductance, interwinding
capacitance, and resonant frequency.
In this case chamferless parts can be used since every point of interwinding
helix path is checked in a search field.
Figure 1 above identifies the potential areas for high di/dt's in an isolated forward converter With such high di/dt's and dv/dt's, it doesn't take much interwinding
capacitance to generate significant common mode currents and voltage spikes of up to several volts.

Tech credits are excellent, Gao Hu's HD lensing maintaining variations of color and texture even in the interwinding
passageways of the underclass world.
Patented flat transformer technology distributes power among multiple cores, resulting in lower leakage inductance and interwinding
The belMag features an operating temperature of 0 degrees to 70 degrees C, and a minimum interwinding
breakdown voltage of 1500 Vrms.
The wire is also insulated to prevent interwinding
shorts that would impact the performance of the component.
Parasitic capacitance, especially interwinding
capacitance of the magnetic components, causes ringing of the voltages and currents initiated by the square wave switching.
Different search trajectories like concentric circles, interwinding
helix or random path can be implemented.
The electrical model of an inductor includes components that represent the copper loss of the coil, the core loss resulting from energy dissipated to excite the magnetic material, and a shunt interwinding
