PT's Appropriate for fast transient detection in ION9000T

Given the high sampling rate of the ION9000T, what Potential Transformers (PT's) do you recommend for monitoring a 15kV system? The concern is that a regular transformer may "mask" or filter the high-speed transients going through it such that the meter will not see them. 

 

One of the groups in Schneider had mentioned capacitor divider circuit but I don't know much about this. 

 

Any recommendation for PT / VT appropriate for ION9000T would be appreciated.

Can't say I know of recommendations, I will ask around and let you know what I find.
