A cable fault under the street
Find it, pinpoint it, dig once. Prelocation, pinpointing and a test van when the network cannot wait.
Electrical test instrumentation / Southern Africa
Find the fault before it finds you.
Lead HV supplies the diagnostic instruments that keep the power network alive. Cable fault location, insulation and oil testing, transformer and breaker analysis, protection relay testing and power quality, from BAUR, Metrel, Hightest and Ponovo, with warranty, training and a calibration lab in Centurion.

What are you trying to find
All applications02
A transformer you do not trust
Ratio, winding resistance and oil quality tell you months before the bang does.
03
Insulation that has to hold
5 kV and 10 kV insulation resistance, plus multifunction installation testing to the standard.
04
A breaker that must open when asked
Timing, travel, contact resistance and vacuum integrity, measured instead of assumed.
05
Protection that has to trip right
Secondary and primary injection, CT and PT analysis, single phase through to six phase.
06
Power quality and daily measurement
Harmonics, dips and flicker on the network, and the meters your team carries every day.
