适用范围:
This standard recommends best practices for the measurement of space charge on high-voltage direct-current (HVDC) extruded cables having rated voltage up to 550 kV. Focus is on poling time, depolarization time, heating and cooling of specimens. Particular reference is made to space charge measurements to be carried out during load cycle qualification tests (either prequalification or type test load cycles). The ultimate goal of this standard is not checking the compliance with any maximum… read more acceptable limit of either space charge or electric field; rathere, assessing the variation of the electric field profile in the cable insulation wall during load cycle qualification tests. read less
