ESTIMATION CRITERIA FOR DEGREE OF PAPER-IMPREGNATED INSULATED POWER CABLE AGEING
Correlation between parameters characterizing mechanical and thermal ageing of paper-impregnated insulation of medium voltage power cables is revealed. On the basis of linear and exponential regression analysis at confidence coefficient of 0.95, critical values of dielectric loss tangent of wrapping...

Electrical Engineering & Electromechanics| Резюме: | Correlation between parameters characterizing mechanical and thermal ageing of paper-impregnated insulation of medium voltage power cables is revealed. On the basis of linear and exponential regression analysis at confidence coefficient of 0.95, critical values of dielectric loss tangent of wrapping and phase insulation corresponding to the cable life termination are found. |
