Electrical Power & Substation Solutions for the Mining Industry

Mining operations require continuous electrical power supply from mine substations and transformers to crushers, conveyors, pumps and processing equipment, every part of the operation needs stable and dependable power. Interruption in the power supply results in direct and indirect losses commercial losses. Poor power quality and poor power factor also results in the increase in the electricity cost and reduces the margins.

CTR offers electrical solutions for power quality, transformer protection, voltage regulation and substation automation. Our products are designed to help industrial power systems. Also provide more reliability, improve equipment performance and reduce avoidable downtime.

Electrical Challenges in the Mining Industry

Mining and mineral-processing facilities often operate large electrical loads and equipment that overburdens additional demands on the power system.

Some common electrical challenges include:

  • Poor power factor increases energy cost
  • Harmonic distortion
    Voltage fluctuations
  • High reactive power demand
  • Transformer faults and fire risks
  • Electrical equipment overheating
  • Unplanned downtime
  • Need for continuous monitoring of substations

CTR offers products and services that address several of these power-system challenges. Its Power Quality range includes power factor correction systems, harmonic filters, reactive power compensators and capacitors.

CTR Solutions for Mining Applications

CTR provides a range of electrical products that can be considered for mining plants, mineral-processing facilities and other heavy industrial applications.

Transformer Fire & Explosion Protection

Transformers are an important part of a mining power system. A transformer fault can result in fire, equipment damage and an unexpected shutdown. CTR’s Nitrogen-based Explosion Prevention and Fire Extinguishing System (NIFPS) is designed for oil-filled power transformers and reactors. The system detects conditions associated with transformer faults and automatically activates through protection relay logic and pressure-sensing mechanisms.

Harmonic Mitigation Products from CTR

Mining and mineral-processing facilities often use large motors, variable frequency drives (VFDs), rectifiers, and other power-electronic equipment that can introduce harmonic distortion into the electrical system. Excessive harmonics can increase losses, cause overheating in transformers and cables, affect sensitive equipment, and reduce overall power-system efficiency.

Harmonic Programmable Filter
  • Hybrid Harmonic Reactor Filters
  • Active Harmonic Programmable Filters
  • Medium- and High-Voltage Harmonic Filter Reactors
  • Low-Voltage Harmonic Filter Reactors
