BS EN 60034-18-1:2010

What is BS EN 60034-18-1- Insulation systems of rotating electrical machines about?  

BS EN 60034 is the European Standard that discusses on rotating electrical machines. 

BS EN 60034-18-1 is one of the parts in the series that deals with the general guidelines for functional evaluation of electrical insulation systems, used or proposed to be used in rotating electrical machines within the scope of IEC 60034-1, in order to qualify them. 

Who is BS EN 60034-18-1- Insulation systems of rotating electrical machines for?  

BS EN 60034-18-1 on Rotating electrical machinery is relevant to: 

• Rotating electrical machine manufacturers 
• Electrical engineers 
• Mechanical industry 

Why should you use BS EN 60034-18-1- Insulation systems of rotating electrical machines?  

Rotating machinery or turbomachinery is a machine with a rotating component that transfers energy to a fluid. In this context, the insulating system is a structure containing one or more electrical insulating materials applied over conducting parts employed in rotating electrical machines. 

BS EN 60034-18-1 provides best industry guidance on the thermal, electrical and mechanical function test. The purpose of the thermal functional test is to provide data which may be used to establish the thermal class of a new insulation system before it is service-proven. Meanwhile, the electrical and mechanical functional tests provide indications on the extent of ageing on insulation systems due to voltage stresses, vibrational stresses, and stresses caused by electrodynamic forces or thermomechanical stresses. 

Overall, BS EN 60034-18-1 can demonstrate the reliability and durability of insulation systems, to enhance the performance and service-life of the rotating electrical machine. 

What’s changed since the last update? 

BS EN 60034-18-1:2010 supersedes BS EN 60034-18-1:1994 + A1:1996 which is withdrawn. The following significant changes are: 

• Provides general guidelines for functional evaluation of different types of windings as before but beyond that for electrical evaluation of windings which are electrically stressed by converter-supply 
• Is now focused on general guidelines with all technical details of procedures and qualification principles moved to the subsequent parts 
• Details additional general aspects of functional evaluation, particularly the statistical procedure for comparison between reference and candidate insulation systems and the Evaluation of minor component or manufacturing changes 
• Contains a new acceptance test for verifying the expected production quality level of the insulation systems 
• Restricts the classification of insulation systems as a result of the functional evaluation to thermal classification.
