Residual Current Monitor

Introducing the RCM410R – An effective solution to earth fault monitoring

Designed to detect and locate developing earth faults, residual current monitors are of critical importance to essential electrical systems and equipment. Whilst providing a level of protection to human life, the permanent monitoring of earth currents within electrical installations and equipment also assists in the avoidance of unexpected power interruption and system downtime. Bender’s range […]

Is your mining application earth leakage relay VFD suitable?

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 […]

NER integrity – do not underestimate the importance

The application of Neutral Earthing Resistors (NER) is one of the most effective ways to maximise personnel safety (limits touch and step potentials) and to minimise mechanical and thermal damage to transformers, cables and equipment associated with earth faults. Neutral Earthing Resistors (NER) have applications in many industries including mining (a requirement under AS/NZS 2081:2011), […]
