esulted in lower

esulted in lower operating and maintenance costs as foreseen over the total lifecycle of the pumps. The pumps have certainly met and exceeded our expectations and the solid technical input and support of the company has been superb from the outset.” All-round solution Echoing the sentiment, AK Roux, projects and asset management manager for QKR Namibia, adds that the new pump station has now run more than 5000 hours without a single breakdown. He added that the project team placed specific focus on the evaluation of the full life cycle cost of the operation and maintenance of the pumps during the design of the new pump station and the selection of equipment. This resulted in pump installation which consume 18% less power under similar operation conditions than the previously installation, while the maintenance requirements over the first 5000 hours of operations was limited to the repacking of the glands and the checking of bearing assembly oil levels.

Correct pump selection is “The success of our slurry pumps in tough Namibian conditions is important to us as it gives us leverage to introduce our slurry pumps to other mines in the region. We are already one of the top suppliers of water pumps to mines in Namibia and the addition of our ultra-reliable slurry pumps enables us Contact: Annett Kriel, KSB Pumps and Valves, Tel: (011) 876 5600 Fax: (011) 822 1746 Email: Web: Petrochemical_Ad_AWC.indd 1 2018/01/27 13:42 7

One-touch, advanced power quality analysis Troubleshoot, quantify energy usage and perform quality of service COMTEST is pleased to announce the availability of Fluke’s range of Three-Phase Power Quality Loggers - 1742, 1746 and 1748 - giving users fast, easy access to the data they need to make critical power quality and energy decisions in real-time. Compact and rugged, these Three-Phase Power Quality Loggers are designed specifically for technicians and engineers who need the flexibility to troubleshoot, quantify energy usage and analyze power distribution systems. Fully compliant with international power quality standards such as IEC 61000-4-30 and capable of simultaneously logging up to 500 parameters while also capturing events, the Fluke 1740 Series helps uncover intermittent and hard-to-find power quality issues easily. The included Energy Analyze plus software quickly assesses the quality of power at the service entrance, substation, or at the load, according to national and international standards like EN 50160 and IEEE 519. An optimized user interface, flexible current probes, and an intelligent measurement verification function allows for digital verification and correct connections make setup easier, considerably reducing measurement uncertainty. The devices also allow users to minimize time spent in potentially hazardous environments, while reducing the need to suit-up in PPE by using a wireless connection (WiFi) to view data directly in the field. Measures all power quality and power parameters The Fluke 1748 logs over 500 different parameters for each averaging period. This allows for the analysis of power quality in detail and the correlation of intermittent events with detailed waveform data, helping to identify the root cause of disturbances. For basic power quality logging, the Fluke 1746 captures all relevant power parameters for performing energy saving studies and electrical network planning with a full upgrade option to 1748 available. For simple load and energy studies the Fluke 1742 offers optimal performance in a rugged package and can be upgraded to 1746 or complete 1748 functionality. Calculates current harmonics limits When downloading data from the Fluke 1748 Power Quality Loggers, Energy Analyze Plus, can calculate the limits of current harmonics based on installation parameters to predict overload of the grid according to a wide range of international standards. This powerful predictive maintenance feature enables current harmonics to be observed before distortion appears in the voltage allowing users to prevent unexpected failures or noncompliance situations and increase system uptime. 1746 Power Quality Logger. Rugged and reliable The 1740 series products are built to withstand tough working environments. The flexible current probes are IP65 rated and suitable for most installation situations; the optional IP65 voltage adapter ensures safe, reliable operation even in harsh conditions. Standard 2m (6.6ft) leads simplify connection on difficult to access conductors, and optional 5m (16.5ft) leads are useful when installing in difficult locations. With the capability of powering the instruments from the power line up to 500 V, installation is simple. Thoughtful design The 1740 series power quality loggers include simple but effective accessories like the MA-C8 adapter making powering the instrument with a line cord easy when not in the field. Ports that aren’t always needed in the field are IP65 protected including the Ethernet, USB, AUX and I/O ports protecting for both moisture and dirt ingress. The status LEDs give a clear indication of what the instrument is doing without having to touch any controls. Its compact size means that in most cases it will fit into the available space easily. Contact COMTEST for more information on the Fluke 1740 series power quality loggers on Tel: 010 595 1821 Email: Easy to use Fluke power quality loggers are designed with the technician in mind. The four current probes are each connected separately allowing flexibility and simplicity, the instrument automatically detects, scales and powers the probes so users don’t have to worry about ensuring the measurements are correct. 8 Analysis and reporting Capturing logged data is just one part of the task. Once you have the data, users need to create useful information and reports that can be easily shared and understood by their organization. Fluke Energy Analyze plus software makes that task as simple as possible. With powerful analysis tools and the ability to create customized reports in minutes users can communicate findings and solve problems to optimize system reliability and show savings. A range of built-in report templates for industry standards such as EN 50160, IEEE 519 and GOST enable one-click reporting to create high quality reports at the touch of a button. Reports can be modified as standards evolve, or new versions become available. 1748 Power Quality Logger.
