IEC 62271-206:2011 is applicable to voltage presence indicating systems (VPIS) incorporated in a.c. switchgear and controlgear covered by IEC 62271-200 or IEC 62271-201. Voltage presence indicating systems are devices used to provide information to operators about the voltage condition of the main circuit of the switchgear in which they are installed. This first edition of IEC 62271-206 cancels and replaces the first edition of IEC 61958. This edition constitutes a minor revision. The main changes with respect of the first edition of IEC 61958 are an actualization of references and the degree of protection which has been changed from IPXXB to IP2X.
