Data for: Improved electromagnetic coil insulation health monitoring using equivalent circuit model analysis

Total number of measurements: 64

For data file “Valve4_DCR_data.mat”: The third column of DCR_avg is the average DC resistance at each time. T is the measurement times.

For the data file “Valve4_RX_data.mat”:

f is the frequency vector

rH is the resistance (real part of impedance) data for the healthy coil (i.e., before the formation of a short)

rHCorr is the correlation of rH with time (Spearman correlation spectrum)

xH is the reactance (imaginary part of impedance) data for the healthy coil (i.e., before the formation of a short)

R_avg is the resistance (real part of impedance) data for the entire experiment

X_avg is the reactance (imaginary part of impedance) data for the entire experiment

R_corr is the Spearman correlation of the resistance with time for the entire experiment

X_corr is the Spearman correlation of the reactance with time for the entire experiment

T is the measurement time vector

res is the index for the resonant frequency over the entire experiment (i.e., f(res) is the resonant frequency over the entire experiment)

Zmag_avg is the impedance magnitude measurements over the entire experiment

Zpha_avg is the impedance phase (in degrees) measurements over the entire experiment
