Like this one, you mean? |
One type yes; this being a two element version of the normal 4 element withdrawable TAA 41 or was that TA41? In this case, there has been a gas surge detected by the Buccholz device that would be assembled on the power transformer. The device was in fact capable of storing the gas sample which would be analysed by a chemist who determine the nature of the fault. Other relays would then determine if it was on the primary or the secondary winding.
Repair costs could run into the hundreds of thousands hence the need to determine the feasibility of any such repair
