Established in 1957 as the first manufacturer of measuring instruments in the region, Metrel offers a wide range of testing and measuring solutions for a wide spectrum of applications. The company develops and manufactures products at a single location, from design to final assembly, quality control and calibration. The MI 3144 Euro Z 800 V […]
The mining industry is embracing automation, but mobile automation technologies are still in the early stages of technology development. As a result, there lacks clear guidance and industry alignment on requirements for managing functional safety. When it comes to requirements for managing functional safety, original equipment manufacturers (OEMs) are at varying stages of maturity, existing […]
The Fluke Ti480, Ti450, Ti400 and Ti300 infrared cameras were recently fine-tuned to create the new PRO series. These tools make it easier for technicians, engineers and electricians to get to root causes faster by identifying hot and cold spots, and apparent surface temperature differentials with a higher degree of accuracy. The upgraded features include increased sensor sensitivity; sharper images for […]
Energize recently had the opportunity to chat to Vivian (Viv) Cohen about his passion for life, South Africa and electricity protection devices. For many years, Viv Cohen served as the South African representative to the International Electrotechnical Commission (IEC), working with other engineers in the design of safety standards for low-voltage electrical installations. Viv Cohen […]
Solar photovoltaic (PV) systems are being installed in ever increasing numbers throughout the world and are expected to produce electricity safely and reliably for several decades. However, many systems are not satisfactorily evaluated prior to being put into service and many have little, if any, scheduled maintenance or testing over their lifetime which could lead […]
Extech has announced the approval and supply of the first mining-approved iWap107s to Sedna Industrial IT solutions. The iWap107 contains a Cisco access point and ethernet switch allowing for copper RJ45 ethernet connection & DSL. Options for fibre optic are also available. Using the iSolate501 Galvanic Exi isolator for antenna connections, the antennas can be classified […]
What is the true cost of mining in the 21st century? How do industrial organisations ensure that their network infrastructures can support the increasing demands and expectations placed on it by management, employees, regulations and processes? Safety improvements and conditions across the mine site have made their way to the top of today’s news headlines […]
It is has been ten years since Megger launched the first circuit breaker test instrument featuring its patented DualGround testing techniques, which contribute to the safety of engineers and technicians. Megger instruments with this capability enable fast and accurate circuit breaker timing, with both sides of the breaker grounded, in more situations than before. Personnel are […]
Pulseclosing technology is an innovative solution where instead of immediately reclosing, the circuit is first “tested” for fault conditions before a reclose is initiated. When compared to conventional reclosing, pulseclosing will reduce the let-through energy of a fault by more than 95%. As such the stress on the system is drastically reduced. Utilities worldwide have used […]
The general procedure for a single-earth grounding point, and a description of a modified approach using a current probe for testing ground resistance of multiple-earth grounding point systems. To measure the earth ground resistance of a single ground electrode at E in Fig. 1, a current is forced to flow to E by driving auxiliary […]
