Reforming
1. Protect the supply and any auxiliary supply so that it cannot be switched on.
2. Construct the circuit according to Fig. 54 and set R to maximum resistance. Switch
on Q and operate K
0
3. Measure the current I
E
4. If I
E
< 3 * I
0
from Table 26, R is to be reduced until I
E
>
3 * I
0
5. Wait until I
E
< I
0
6. Set I
E
> 3 * I
0
and return to section 5
7. End the reforming process.
Note:
Depending on the condition of the capacitors reforming may take several minutes and
should be carried out while carefully observing the input current I
E
