Network switching & HV tap change on a cast resin transformer to reduce the secondary voltage

This is a record of HV/LV network switching & HV tap change on a cast resin transformer to reduce the secondary voltage. The 3.3kV system normally operates at 3.4kV which can cause over-voltages on the LV distribution network during plant outages (no-load conditions).
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!
