Technology Supporting the Mining Industry

Power Protection

CSE W Arthur Fisher provides advanced power protection solutions designed to ensure safe integration of renewable energy sources and improve asset reliability. Features such as synchronisation, load shedding and real-time monitoring help maintain system stability and performance. Our suite of Protection Relays, including the GE Multilin range, offers robust protection against faults and disturbances, while our Current Limiting Protectors (CLiPs) safeguard critical equipment in high-demand, complex electrical environments.

HV/LV Motor Protection and Control

We offer a range of motor protection and control solutions suited to severe, heavy and standard duty applications. Our motor starting technologies extend equipment life and reduce unplanned maintenance. With Variable Speed Drives such as the Fuji Frenic series, energy flow is precisely controlled for both variable and constant torque applications, improving process control and reducing energy consumption. Our Soft Starter range minimises electrical stress, while the Unistarter EPMA Series Liquid Resistance Starters (LRS) deliver reliable performance for large slip ring motors in mining, cement and water sectors.

Condition Monitoring

Our vibration monitoring systems enable early fault detection in equipment such as crushers, mills and conveyors, improving reliability and safety. With thermal and visual monitoring technologies like Systems With Intelligence (SWI), assets including underground operations and substations can be monitored in real time for proactive maintenance and improved operational efficiency. Additionally, our dissolved gas analysis solutions provide continuous online monitoring of transformers, offering rapid alerts for emerging faults and supporting timely intervention.

Power Quality Monitoring and Correction

Partnering with industry leaders like Elspec, we deliver comprehensive power quality monitoring and correction solutions tailored to the mining sector. Our range includes Power Quality Meters, Analysers, Filters and Fault Recorders, designed to maintain grid stability and ensure a secure, reliable power supply. These systems help identify opportunities for energy optimisation and address performance issues swiftly.

Critical Communications

Our critical communications technologies are purpose-built to meet the evolving demands of mining and industrial operations. These solutions enable real-time monitoring of production parameters, equipment status and environmental conditions. Through partnerships with Siemens and GE Vernova, we supply rugged switches and routers for reliable connectivity in harsh environments. Our expertise in RF and SCADA communications ensures robust infrastructure for remote monitoring and control.

Remote Power Systems

CSE Linked, a premium provider of renewable energy solutions, offers clean, cost-effective and sustainable power systems built to withstand New Zealand’s diverse conditions. From fully off-grid systems to locally fabricated innovations, we support the mining, resources, construction, agricultural and government sectors with solutions designed to meet evolving energy demands.

Flow Control

Flow control solutions, including actuators and positioners, are critical in mining and heavy industrial operations, where they automate the control of slurry, water and chemical flows in harsh environments. Their durability and precision help reduce downtime, improve safety and support efficient material handling and processing. Partnering with technology leaders like AUMA and Schneider Electric, flow control is key to achieving safe, efficient and cost-effective operations.
