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.”

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.
