Wire Stripping - Voltech AT3600 User Manual

ENERAL OTES
Terminals or interconnections, which have exposed (high voltage) metal in contact
with the surface of the fixture board, should be avoided where possible, as there may
be creepage along the surface. If such a terminal is necessary, you must ensure that
there are no sharp points or corners on the metal pieces, that the surface between
them is scrupulously clean, and that a separation of at least 3mm per kV is used.
4.2. K
Always use Kelvin connections (e.g. separate power and sense leads) between each
socket pin and the corresponding power and sense Contact Pins on the Fixture Board.
In addition, when measuring very low transformer impedances; make sure that the
Kelvin connections are continued through the terminal to the transformer leads.
4.3. M
Always use terminals, sockets or probes that are mechanically robust.
mechanical connections can affect the measurements, and hence your throughput and
quality of product.
In use, clean the fixtures and connectors regularly, to avoid any build-up of dirt and
transformer varnish. Dirty fixtures give poor contacts and poor insulation resistance
between contacts, and could reduce the quality of your product.
Use a separate fixture for each type of wound component, as this can improve the
testing throughput.
Design the fixture so that the connections to the component under test can be made
quickly and easily. One example is to use guides to ensure that the component cannot
be put on to the fixture the wrong way round.
4.4. W
It is most important that when removing insulation from single core wire that the
conductor does not get marked or damaged when stripping as this will fracture in
time when in use.
