| It is undesirable for the overvoltage ratio to be less than 2, on the grounds that below this value intensity and peak-to-background ratio decline significantly. |
| A solenoid can hammer itself to pieces from excessive force caused by overvoltage or by a reduced load in the return spring it is pulling against. |
| Maximum transient overvoltage on healthy phases occur if the earth fault happens at the instantaneous voltage maximum in faulty phase. |
| The ADG4612 and ADG4613 switches also feature overvoltage protection, which can block signal levels up to 16 V in the off state. |
