EA Technology has launched the most
effective instrument yet for identifying
defects in live cables of distribution
voltages.
The CableData Collector works by testing
for partial discharge (PD) activity: small
discharges, which result in damage to the
cable, and if left unattended will lead to
insulation failure.
EA Technology commercial director
Neil Davies said: “Measuring PD activity
is a very accurate way of assessing the
condition of cables and their likelihood of
failure and outage.
“The ability to test cables without the
need to de-energise them is a real benefit.
Essentially, they can be fixed before they
fail and cause expensive outages.”
The instrument quickly detects PD
activity in live cables by measuring radio
frequency currents. It works with most
types of single and three phase insulated
cables at distribution voltages, up to
several miles/kilometres in length.
Information about PD activity is recorded
by the CableData Collector hardware
and can be sent to EA Technology for
expert analysis. Alternatively, users can
buy EA Technology’s software package to
perform their own data analysis. In either
case, they will have access to clear reports
on cables affected by PD activity and
recommendations for remedial action.
CableData Collector instruments are
supplied as complete, ready-to-use kits,
with Radio Frequency Current Transformers
(RFCTs), cabling, USB-powered data
collection unit and carry case, together
with optional software, training and factory
technical support. Kits are also available
for rental, or EA Technology engineers
can provide cable testing as a site service,
anywhere in the world.

Launch of new fine wire spooler
Cemanco has launched a KMK fine wire spooler and re-winder for material down
to 0.05mm (0.002") diameter. The design is modular and allows the integration of
mechanical as well as a dual laser controlled traverses for high quality windings. The laser
guided flange detection system allows precise winding of bi-conical and stepped spools.
All control functions are accessed and displayed by means of a single control wheel
and a digital display. Displayed functions include spool rpm, length of material, rpm
up and down ramp and basic settings like maximum rpm, sense of rotation and dancer
settings. Take-up spool speed can range from 0 to 2,800 rpm and in this configuration
the maximum pay-off spool weight is 15kg.
