Subject: REQ for info (HV insulating fluid)
I have just acquired a wideband HV 'scope probe, a Tektronix P6015.
The probe will work upto 13kV unfilled, or 40kV when filled with a freon
insulating fluid. These ratings are for the total DC and AC peak, upto
The freon is no longer available due to bans on CFCs etc. so I have some
questions to allow me to find something equivalent, if i eventually need to
1. Does anyone know the name, number or spec. of the original grade of freon
which was used? I need to know the dielectric strength and also the rel.
2. Can anyone suggest an alternative fluid?
Thanks in advance,
