IVWV***: Instruction for high-voltage end groups
IVWV*** covers responsibility for work on high-voltage end groups, such as transformer panels and secondary switch panels. 35 exam questions plus switching programme (schakelbrief) exercises prepare you.
Core responsibilities at an HV end group
At HV end-group level you must handle your responsibilities as an IVWV with extra care: mistakes have bigger consequences because of the higher voltage and energy content of the network.
- Supervising AAB measurements before earthing
- Assessing switching programmes before they are carried out
- Checking where the selection device (SEL) is placed
- Drawing up work permits for HV end groups
Responsibility for the switching programme
An IVWV*** must be able to draw up and assess complete switching programmes. Our switching programme exercises let you create both alpha and beta switching programmes for T10 transformer scenarios, with AI feedback on your logic.
