Is your mining application earth leakage relay VFD suitable?

May 18th, 2016 Filed under Safety and Protection Relays

The mining industry is experiencing a growing number of applications of Variable Frequency Drives (VFD) to soft start and control motors driving shovels, draglines, hoists, conveyors, longwalls, mills, fans and pumps. However, it is often ignored that not all compliant AS2081:2011 earth leakage protection relays are suitable for installations involving VFDs. In AS2081:2011 it states that should a […]
