Abstract :
A summary is presented of ANSI/IEEE C57.13.3, `Guide for the Grounding of Instrument Transformer Secondary Circuits and Cases´. It is intended to provide consistency in grounding practices for electric equipment that impacts personnel safety and proper performance of relays at power-line frequencies. It includes those practices generally followed today, with revisions where present experience and practice indicate this to be desirable, and it makes recommendations in areas not previously addressed. The aim of this report is to promote an awareness in the industry of the concerns for personnel safety and equipment performance, and to provide an opportunity for written dialogue that could result in improvement in the standard´s content and application
