Determination of parameters of equivalent cable circuit for “EI-2” category tests
The dependence of the test equipment performance requirements on the cable insulation properties and the conditions of their in-process measurement is analyzed. Recommendations are given on the selection of the test equipment energy parameters based on the analysis of the polymer insulation physical parameters
Insulation integrity; “EI-2” category voltage test; test voltage distribution on the insulation surface; change of equivalent insulation electric capacitance per unit length; change of dielectric losses.
