New cable and pipe locator
Built on a proven design, and with Pathfinder SAF Technology at
its core, the 8879v3 offers RYCOM’s most advanced signal acqui-
sition and filtering technology.The 8879v3 cable and pipe locator
offers a utility locator FrequencyFlex allowing users to adapt the
system to their specific needs. Multiple active frequencies allow
the user to accurately locate the cable and / or pipe with minimum
interference and maintain the ability to continue locating past faults
and around conduit bends. Passive frequencies identify ‘live’ and
charged lines by their naturally occurring electromagnetic fields.
The 8879v3 offers multiple passive frequencies – 50 Hz, 60 Hz,
Radio Frequency, Cathodic Protection Rectifier and CATV allowing
line locating without the use of a transmitter.
Updated transmitter functions include improved transmitter
induction, multi-frequency coupled induction ranging from 8 kHz
to 118 kHz, and automatic impedance matching for direct connec-
tions.The 5W or 10W transmitter has the ability to simultaneously
apply two frequencies to a utility. From one transmitter setting the
user can locate the main line as well as other services by ‘lighting
up’ the entire site. This set-and-forget feature streamlines opera-
tion by reducing the need to repeatedly relocate the transmitter. All
functions are accessed via weather-proof membrane buttons and
both user input and transmitter status are verified with audible re-
sponses.The ergonomically designed and balanced 8879v3 receiver
provides instant push-button depth up to 7,6 metres and current
measurement to help identify target utilities in crowded easements.

Leak-detection in coal-fired
power stations
Instrotech - a Comtest Group Company - has de-
signed and developed at the request of and, in
consultation with the South African Power Utility
(where 93% of all electricity is currently generated
using coal) an advanced acoustic leak detection
system called Inspecta FFT, to detect boiler tube
leaks in coal fired utilities as well as in oxygen plants
and gasifiers.
This technology and equipment is now in use in
power stations worldwide, where the early detection
of tube leaks to reduce down time and prevent con-
sequential damage is vital. According to the World
Coal Association, the importance of coal to electricity
generation worldwide is set to continue, with coal
fueling 44% of global electricity in 2030. (Source
IEA 2010). The Inspecta installed base
includes power stations in
South Africa, Germany,
Australia,Turkey, India,
Malaysia and China.
Authorised distributors in
these countries are on hand to
provide all the services required
to provide high levels of pre- and
post-sales support as well as any spare
parts required to keep the systems run-
ning efficiently.

manding specifications
and to render complex
repairs in accordance with
the necessary quality was
a big differentiator for us.
We can leverage an im-
pressive 57 years of indus-
try experience in both the
local and global market as Africa’s largest medium voltage machine repairer,”
adds Botton.
