Smart meter tripping RCD anymore than anecdotal evidence?

The meter in the photo is a Megger MIT420/2 and can measure micro Farads, as an installation electrician that is not a feature of the meter I used.

Edit- I have just turned it on and the display is in nano Farads.

I have to own up the meter was brand new on EBay being sold by a firm of motor factors remarkably cheap, I presume they thought they would sell them to mechanics working on  electric vehicles and when they did sell they knocked them out on EBay dirt cheap to get rid of them, not being able to resist a bargain I bought one, but still have not worked out what all the features are or used them.

I fitted a time delayed 100mA up front R.C.D. before  a new consumer unit which had a TT supply. Each circuit had 30mA R.C.B.Os.

I assured the customer that the system would  be reliable as the original 30mA R.C.D. often tripped and plunged them into darkness.

Later I got a call saying that they had lost all power. The 100mA time delayed R.C.D. had tripped off. No R.C.B.Os tripped off.

The installation was converted to a P.M.E. earth terminal system by U.K.P.N. and the 100mA R.C.D. was replaced with a 100 Amp D.P. main switch.

The house was near to the Bacton gas terminals. Was the tripping  caused by radio interference?

We may never know.
