Guidelines for choosing type of surge protection

:: To choose the right type of surge protection at the distribution frame, certain principles must be considered, such as quality of service, costs and safety of the personnel. Causes of dangerous surges i.e. overvoltages and overcurrents could be:

- inductive influence of near high voltage plants
- cross-contact between the power and the telecommunication line
