Latest generator set technology available in Africa

The QSK95 generator sets are Cummins Power Generation’s most powerful diesel generator sets to date, offering up to 3,5 MW 60 Hz and 3.75 MVA 50 Hz.They are engineered with the highest kilowatt per square foot ratio in their class, resulting in a smaller footprint that achieves a 20 % improvement in power density. The durable and robust QSK95 Series generator sets are ideally suited for mining, oil and gas, or any project where harsh conditions, challenging environments and the demand for reliable, continu- ous remote power exist.The QSK95 Series generator sets are also engineered to deliver reliable, mission critical power protection without interruption — an uptime requirement shared by data cen- tres, hospitals, water and wastewater treatment plants, and utilities. Cummins Southern Africa power generation director, Kobus Coetzer, points out that the new generator sets boast more power and best-in-class fuel economy. “Over the course of 8 000 hours

of operation, the QSK95 can achieve fuel savings of more than US$400,000 (R4-million+). The QSK95 Series is designed to lower the total cost of ownership by reducing installation expenses, fuel costs and maintenance requirements — all while maintaining Cum- mins’ high standards of reliability.” Enquiries: Kobus Coetzer.Tel. 011 321 8700 or email kobus.coetzer@cummins.com

Monitoring relays – reliable machine protection

Drawing on more than 50 years of experi- ence in manufacturing monitoring relays, the compact K8 series continues the long tradition in providing reliable machine protection and safeguarding. Omron has now completed this popular product range by adding six new models for three-phase monitoring. These additions to the range mean that now, virtually all machine monitoring func- tions can be conveniently implemented with the same range of products, with the added benefit that all of the products comply with global safety standards.

The new monitoring relays feature ad- vanced switching power supply technology and generate almost no heat.This ensures that they have long reliable product life- cycles and also allow the K8 relays to be mounted closely to one another and to other components, saving valuable control panel space. K8 monitoring relays are available in versions for both single- and three-phase applications and provide a wide range of solutions for detecting common issues such as under- and overvoltage, phase loss, under- and overcurrent, over temperature,

phase sequence errors, and voltage asym- metry conditions. Omron also offers ther- mistor motor protection relays that directly monitor the temperature of motor windings. Added to this are the contact-type outputs – all of the new monitoring relays incorpo- rate LED indicators that show equipment status, which greatly simplifies machine troubleshooting and allows corrective action to be taken, before any lasting dam- age can occur, therefore avoiding costly machine downtime.

New range of switchgear on local shelves

Schneider Electric , the global specialist in energy management, has launched Easy9 switchgear, a new range to help electricians with the provision of reliable switchboards in southern African homes and small-sized buildings. A leader in switchgear technologies since the 1920s, Schneider Electric has engineered Easy9 to be affordable without compromis- ing on safety and reliability. According to Christo Janse van Rensburg, product manager: final distribution, at Schneider Electric SouthAfrica, Easy9 answers the need for electricians to have access to robust products that are widely available, and will also help them to complete their installa- tions swiftly and professionally. The range covers miniature circuit breakers, residual current circuit breakers, surge protection devices, comb busbars, and switchboard enclosures. All Easy9 products are manufactured in IS09000-certified plants belonging to Schneider Electric and are approved by independent authorities as compliant with local electrical safety standards. “We work closely with electricians worldwide to help bring safe electricity to homes and buildings around the globe. With Easy9 electricians can take pride in delivering the enhanced safety and

peace of mind their customers deserve. An advantage too is that it is a high-end device available at a mid-range price,” adds Janse van Rensburg. Enquiries: Ntombi Mhangwani.Tel. 011 254 6400 or email ntombi.mhangwani@schneider-electric.com
