4kV DC Insulation Test of 1kV Rated Cables - Why Are We Doing That?

This is a record of the process and equipment used to test 1kV single-core un-armoured cables that had initial low insulation values when tested at 1kV (some as low as 35M ohms). The cable manufacturer-recommended we test the cables at 4kV DC to prove the integrity of the cable insulation and installation.
From design through to certification, let's give you a glimpse inside the world of the industrial electrical environment covering systems, networks & apparatus up to 33kV and down to 24VDC!
