EVS-EN 60831-1:2014

IEC 60831-1:2014 is applicable to both capacitor units and capacitor bank s intended to be used, particularly, for power-factor correction  of  a.c. power systems having a rated voltage  up to and    including 1   000 V   and frequencies  of 15 Hz  to  60  Hz. This  part of IEC  60831  also applies to capacitors intended for  use in  power  filter circuit s. Additional definitions, requirements,  and  tests for  power filter capacitors are  given in Annex A. The object   of this part of IEC 60831 is to:  - formulate uniform rules regarding performances, testing and rating;  - formulate specific safety rules;  - provide a guide for installation and operation. This third edition cancels and replaces the second edition published in 1996 and Amendment 1:2002. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:  - Updating of the normative references;  - Test conditions have been clarified;  - Thermal stability test has been clarified;  - Maximum permissible voltage and current have been clarified;  - The protection of the environment has been amended with safety concerns and plastic quality requirements. Keywords: capacitor units and capacitor banks, uniform rules regarding performances, testing and rating; safety rules; guide for installation and operation
