REAL 3 PHASE TEST AND TAG
3 Phase Equipment, normally class I (protectively earthed) with an electric motor or motors,
requires two tests in order to be tested in accordance with ASNZS3760.
The first test is checking the protective earth conductors resistance and its ability to conduct a
fault current back to the ground. A 25Amp test proves the earths integrity not just its continuity
therefore a tester than can produce 25Amps (rather than the all too common 200milliamp
compliance testers) is best for this. The leakage of electricity to the ground is measured in the
second test.
A 500 volt Insulation Resistance Test will not usually be acceptable because of the need to
close switch contacts, which is normally only possible by powering up the equipment. The best
solution is to use the differential leakage method due to possible alternative earth paths giving
unreal leakage results.
NORWEGIAN INNOVATOR
CREATES ROBUST 3D PRINTER WITH VESCONITE HILUBE
Vesconite
Norwegian innovator Kent Thoresen, of 9axis AS, is trialling Vesconite Hilube
sleeve bushings as part of his creation of a robust, reliable and quieter 3D
printer.
His current 3D printer is very stiff and dependable and an improvement
on many of the low-cost flimsier designs that are available. It is tough and
technically solid and does not require calibration if the plates are moved, unlike
many of the less sturdy commercially-available designs.
The current trial also involves the use of Vesconite Hilube bushings - one of the
components that are intended to add to the robustness of the printer.
Vesconite Hilube 3D printer bushings are valued by many in the industry for
being grease free, low friction, less noisy and more hard wearing than their
counterparts.
