CapCoal: E300 Motor Protection Relay Configuration

High Voltage

The Challenge

CapCoal needed to configure and commission E300 motor protection relays across their operation, requiring precise parameterisation of overload protection, trip logic, and control settings to match their specific equipment requirements. Factory acceptance testing demanded rigorous configuration verification to ensure reliability and compliance before deployment to site.

Our Approach

Deftec’s team conducted detailed Factory Acceptance Testing (FAT) on the E300 relay configuration, establishing IP connectivity via DHCP, and systematically configuring over 30 critical parameters across current-based, voltage-based, power-based, and control-based trip logic. We tailored settings including full load current ratings, trip class selections, and reset modes to CapCoal’s operational needs---for example, adjusting FLA settings from default 50A to 25A to match their motor specifications. The configuration documentation provided a comprehensive checklist covering equipment setup, parameter programming, and test sign-off, ensuring consistency and traceability across all relay installations.

The Outcome

CapCoal received fully commissioned E300 relays ready for deployment, with documented configuration settings and validated protection logic. This approach minimised on-site commissioning time and delivered confidence that motor protection would function as designed across their mining operation.
