BS EN 50468:2009

What is BS EN 50468 - Overvoltage resistance of equipment with telecommunication ports about?

BS EN 50468 specifies the minimum level of resistibility of equipment having telecommunication port(s) to overvoltages and overcurrents.

BS EN 50468 covers telecommunication equipment installed at customer premises.

Overvoltages or overcurrents covered by this BS EN 50468 are surges due to direct or indirect lightning on the telecommunication line plant.

Note: Overvoltages or overcurrent not covered by BS EN 50468 are:

• Short-term induction of alternating voltages from electric power systems (including electrified railway)
• Earth potential rise due to power faults or load switching
• Direct contacts between telecommunication lines and low voltage power lines

Who is BS EN 50468 - Overvoltage resistance of equipment with telecommunication ports for?

BS EN 50468 on resistance requirements to overvoltages and overcurrents due to lightning for equipment having telecommunication ports is useful for:

• Telecommunication service providers
• Electrical engineers
• Manufacturers of telecommunication equipment

Why should you use BS EN 50468 - Overvoltage resistance of equipment with telecommunication ports?

Overvoltages and overcurrents that occur due to lightning can affect the integrity of devices connected to telecommunication ports.

BS EN 50468 provides you references to test methods and test conditions to verify the resistance of equipment having telecommunication ports to overvoltages and overcurrents. BS EN 50468 also specifies the resistibility values that the telecommunication ports must meet, this helps you to ensure that they can maintain voltage and current when there are power surges due to lightning.
