Australia High Voltage Switching
High voltage switching is something that is required on a regular basis across different industries. However, it is of the utmost importance that high voltage switching is only carried out by personnel that have the necessary experience and qualifications to do so. Additionally, the personnel that engage in high voltage switching need to be certified on a regular basis.
This means that anyone who engages in high voltage switching or any other related activities needs to partake in regular training sessions and update their knowledge with regards to the latest safety norms and procedures, as well as any other legal obligations and requirements. High voltage switching is a complex activity and, as such, it is totally illegal to have an unqualified person attempt to engage in the process themselves or even be involved in it for that matter.

In a capacitor, why does the positive plate always have the high voltage?
Hi. I'm just starting out with high school physics and I would like to know why the positive plate in a parallel plate thingy (capacitor) always has the high voltage. Also, why does the electric field flow from the positive plate to the negative one. I thought only electrons could move, so wouldn't it be the opposite way?
*I meant to say "higher voltage". Sorry.
It's a convention that comes from before we knew about electrons. Early scientists knew something was flowing in circuits but they didn't know what it was. They arbitrarily decided to say current flows from the positive to the negative side of the battery. Even though we now know that electrons flow from the negative side of the battery the original convention lived on.
