JB Switchgear Solutions was recently
awarded a contract for the design,
manufacture and supply of various
motor control centres destined for
the Gangama Dry Mine in Sierra
Leone.
Mineral Sands producer, Sierra Ru-
tile, awarded Phase 1 of the project
to global engineering company DRA,
on a lump sum turnkey basis, with
first production targeted for the end
of the second quarter of 2016. Ulti-
mately, the project will be developed
in two phases, each a separate 500
tph operation. Sierra Rutile’s lease
in Sierra Leone is the world’s largest
known deposit of natural rutile,

A FULL range of approvedminiature cir-
cuit breakers, offering protection against
overload and short circuit in electric
conductors, is available fromZestWEG
Group. TheWEGMDW andWEGMDWH
miniature circuit-breaker line comply
with the tripping characteristic curves B
and C, according to Standards IEC 60898
and IEC 60947-2.
These miniature circuit breakers have
been developed to be used in low volt-
age circuits with direct or alternating
current from 2 to 125 A and short circuit
breaking capacity up to 10 kA. The full
range includes all accessories in both
5 kA and 10 kA, making it possible for
the ZestWEG Group to supply custom-
ers with complete solutions for specific
projects.
All theWEGMDW andWEGMDWH
miniature circuit breakers can be used
in both commercial and domestic ap-
plications.

Electric’s specialists and entail the op-
eration and installation of its renewable
energy products, as well as the con-
cepts required to become an entrepre-
neur. With this theoretical and hands
on training, learners can start their own
informal businesses on the side when
they identify an opportunity to create
access to energy in their community.
The ECA’s accredited training centres
are located across South Africa and pro-
vide a wide range of training and skills
development courses, aimed at both
the technical and business aspects of
the electrical contracting industry. The
ECA has been representing electrical
contractors in South Africa for 60 years.
Says George Senekal, regional train-
ingmanager at the ECA:“The training
provided by Schneider Electric not
only focuses on the normal protective
equipment used by electrical contrac-
tors but has taken this a step further by
initiating a joint venture training pro-
gramme with the ECA, which exposes
our learners throughout the yearly
training programme on a topic that is
highly important to global energy sav-
ing techniques.”
He says the topic dealswith the“very
basics to solar energy generationprinci-
ples”and that after one session candi-
dates have a soundunderstanding
of the meaning of solar energy genera-
tion.
“Our candidates are also clearly
informed by the Schneider Electric
training staff on how to be a success-
ful entrepreneur in this specific field of
solar energy distribution,”says Senekal,
adding that current technology as well
as future technology is well presented
by the Schneider Electric training staff.
“We look forward to enhancing this
initiative to a more advanced and
hands on approach. Our industry is
represented by our learners, andmore
specific training techniques will ensure
a better knowledge and implement-
ing of renewable energy resources,”
concludes Senekal.

and has beenmined since the early
1960s.
As opposed to dredge mining,
which targets ore that is submerged
in water, dry mining involves the ex-
cavation of ore in a dry environment.
The Gangama dry mining project
involves the excavation of Sierra
Rutile’s Gangama deposit using
conventional earthmoving equip-
ment, which will deliver mineralised
ore to a concentrator located on site.
The mineral concentrate will then
be processed in the existingmineral
separation plant along with feed
from the Lanti Dredge mine and the
Lanti Dry mining project.
In this instance, JB Switchgear’s
scope includes three‘Eagle Series’
motor control centres, two of which
are installed inmodifiedmarine
containers, and one is an outdoor
kiosk type MCC.
The incomers are rated at 2 500 A
for a 480 V/60 HZ system, with a fault
level of 50 kA. Electronic overloads
with Ethernet communication
protocol is used for control. The order
also includes a number of variable
speed drives (VSDs) soft starters and
distribution boards. Completion of
the order is scheduled for
October 2015.

THE Comtest Group, Fluke’s authorised test andmeas-
urement distributor for South and southern Africa, has
introduced Fluke CNX, a customisable, troubleshooting
tool set of wireless test tools that work together, record-
ing live measurements remotely and simultaneously on a
single screen.
CNXmodules measure ac voltage, temperature and ac
current with a standard clamp or flex clamp. Possible
New remote, simultaneous, recordable
wireless test tool system
applications include:
• Detection of power interruptions
• Single phase measurement
• Determining current imbalance
• Measurement of incoming current
A wireless multimeter displays readings fromup to three
wireless modules, plus the meter measurement at the
same time, on the same screen, from as far as 20 m away.
To get a holistic overview of the situation, readings from
10 tools measurements can be reviewed simultaneously
on PCView. Users are able tomix andmatch the wireless-
enabledmodules to suit their unique measurement needs.
The CNX system can record up to 65 000 sets of min/
max/avg readings in either single or multiple logging
sessions. CNX isolates intermittent events or records signal
fluctuations automatically, using the module’s log func-
tion. Measurements can be viewed in a location separate
from the point of measurement, for safety purposes, as
well as be viewed repeatedly from either remote locations
or on-site.
Fluke CNXmeets Category 1 000 V CAT III and Category
IV 600 V safety standards.
