Industrial power quality standards

  Power quality becomes more and more important as energy efficiency equipment is brought into use in industrial networks, and as embedded generation is installed in distribution networks and own generation equipment is brought into use by industrial users. This article examines the standards for both utility networks and industrial users. All networks, however well […]

Connecting and sealing cables in the mining industry

  The connection and sealing of cables to electrical equipment used within any industrial project is an important aspect of the safety and ultimate success of the project, but often a source of significant aggravation when things go wrong. This is none more relevant to anywhere else than in the mining industry, due to a […]

Replacing a HV mining substation with a modular design

  Mining sites are often located in some of the most inhospitable and logistically challenging areas of the world. Mining operators are increasingly turning to the modular “e-house” design for their electrical systems to overcome these challenges. TGood Electric successfully applied the concept to a 110 kV high voltage mining substation in central Asia. Located […]

Grounding methods in mission critical facilities

  Many factors must be considered when designing the electrical system for critical facilities, such as winders on mines, not the least of which is the type of grounding system to be used. Proper grounding reduces overvoltages, improves uptime, and isolates faults. Grounded systems offer many benefits over ungrounded systems [1, 2, 3]. When properly […]

Improving power quality in real-life applications

  Poor power quality is one of the principal reasons for inefficient power usage and electrical equipment failure. Power quality refers to the maintenance of electrical parameters including voltage and frequency. Dips and spikes in supply voltages are common in many industrial environments and are usually caused by the switching on and off of heavy […]

Modern building management systems tackle efficiency of energy, utilisation

  Buildings must keep pace with today’s fast-paced business world. The widespread adoption of information and communication technology, including computerised building management systems, reflects this trend. But implementing new technology is not enough. Amid pressure to constantly improve performance, businesses are making increasing demands on their employees to be more responsive and mobile. Compared to […]

Dynamic reactive power compensation of container cranes

  Overall requirements for the reactive power compensation of a container crane vary based on overall crane size and container weights. These dynamically changing requirements affect not only the efficiency of the crane, but also put a significant strain on the local electrical distribution system. Download the PDF
