Can anyone advise me on what I should be considering when planning to use a sheet of perspex to segregate a person from a live electrical conductor 690v.

Consider that Perspex (TM) or methyl methacrylate, is brittle with low impact resitance. Polycarbonate is much tougher and also transparent. I am assuming that clear plastic is required. Specific electrical properties should be available from the supplier and manufacturer. perhaps you should also also look at their behaviour when heated and their respective products of combustion.

clear plastic is often used to cover live terminals so they are less likely to be touched accidentally of course if the front panel is open during work or testing. but there would still be a metal front cover that would be secured to stop unauthorised people getting in there and also to offer suitable IP protection from weather and people poking things in there.

Seriously I would get a qualified electrical engineer to look at this and let him decide what action to take
