BS EN 50160:2010+A3:2019

What is BS EN 50160 - Voltage characteristics of electricity supplied by public electricity networks about?  

BS EN 50160 is a European standard that focuses on voltage characteristics of electricity. BS EN 50160 defines describe and specifies the main characteristics of the voltage at a network user's supply terminals in public low voltage, medium, and high voltage AC electricity networks under normal operating conditions. 

Who is BS EN 50160 - Voltage characteristics of electricity supplied by public electricity networks for? 

BS EN 50160 on voltage characteristics of electricity and public electricity network is useful for: 

• Public electricity networks engineers 
• Public electricity network providers  
• Government authorities  
• Companies providing electricity  

Why should you use BS EN 50160- Voltage characteristics of electricity supplied by public electricity networks?  

The objective of BS EN 50160 is to define, describe and specify the characteristics of the supply voltage concerning: 

• Frequency 
• Magnitude 
• Waveform 
• Symmetry of the line voltages 

Voltage is subject to variations during the normal operation of a supply system due to changes of load, disturbances generated by certain equipment and the occurrence of faults which are mainly caused by external events. 

Some of the phenomena affecting the voltage are particularly unpredictable, which make it very difficult to give useful definite values for the corresponding characteristics. The values are given in BS EN 50160 for the voltage characteristics associated with such phenomena. 

What’s changed since the last update?  

BS EN 50160:2010+A3:2019 supersedes BS EN 50160:2010+A1:2015. BS EN 50160:2010+A3:2019 includes some technical changes concerning BS EN 50160:2010+A1:2015. These include: 

• New organization of the document by grouping clauses related to events and continuous phenomena 
• Modification of some definitions and completion by some new definitions 
• New clause 6 relevant to voltage characteristics in high voltage networks
