Oven still tripping rcd?

If you are capable of changing an element, then you are 90% there with the testing. Just disconnect the elements, insulate the wire ends you disconnect, then power up and see if anything trips. If no trip, reconnect one element and repeat the test. Keep going with the test, until you find the one causing the trip.
That, assumes it is an element to blame. If despite disconnecting all the elements, it still trips, then you will need test equipment.
Thanks everyone for the suggestions. I had an electrician come out and sods law that the oven turned on, didn't trip and performed faultlessly for the 20 mins he was there. He couldn't see any obvious damage to any of the wiring and suggested it may have just been a bit of moisture on the new element. He didn't charge me a penny either, which was very good of him.
Obviously further investigation needed if it does happen again.

Using the oven tonight. Tripped out again after 10 minutes. Flicked the breaker back on and it's happily been on for the last 5 minutes. Oven heating up fine and fan working. These intermittent faults are the hardest to diagnose!? @Harry Bloomfield
That suggests to me, that it is one of the elements, which is suffering moisture ingress. The element, runs in a metal tube, insulated from the metal by magnesium oxide, which is an insulating white powder, packed in tightly. The problem is, the powder, if exposed to the atmosphere, it is very absorbent to moisture in the air. With heating and cooling of the element, the moisture can be driven out, or driven along the element, so the tripping can appear quite random. So any pinhole leak, or moisture trapped during manufacture of an element, might be the cause of your trip.
As already said - they way you can diagnose it is by disconnecting the elements, insulating the bare connections, and a bit of patient testing. A quicker way, which your 'electrician' ought to have done, is to test it out with an insulation tester.
An additional point you need to be aware of, is either a L to E, or N to E leak, can be the cause of the trip - you may not actually need to have an element turned on, for it to cause a trip, because only the L will be switched by the oven controls. The N will remain connected, and able to cause a trip.
