Acceptance testing involves:
 Electrical checking of closing and opening at the
prescribed normal, maximum and minimum
permitted auxiliary voltage.
 Checking the operation of auxiliary contacts, relays,
coils and meters.
 Wiring checks.
 Measuring of contact resistance values in the
primary circuit.
 Withstand voltage testing of the secondary circuit
(except the spring charging and closing motor coils).
 Withstand voltage testing of the primary circuit.
 Visual inspection to establish whether the materials
and installation are in accordance with
specifications.
5.1.2

Inspections

After the installation has been set up, and no loads are
connected physical inspection should be carried out and
will include the following:
 Measurement of voltage losses on the busbar
connections fitted on site.
 Checking mechanical interlocks and satisfactory
insertion and withdrawal of the withdrawable units.
Checking installed continuous wiring to confirm that

it is in accordance with specifications and drawings.
 Applying power to the installation in accordance with

Decommissioning

5.2.1

Dismantling

Prior to dismantling, ensure that the entire
installation is dead (primary and secondary).
The withdrawable units are not designed for field
dismantling and should be returned to Eaton
complete and as removed from the switchgear.
The following safety measures must be taken when
dismantling the switchgear
 During dismantling use protective equipment such
as safety goggles, gloves, protective footwear and
dust hoods.
 Watch out for sharp edges.
Use suitable and safe tools.

5.2.2

Disposal

®
Power Xpert switchgear should be disposed of in an
environmentally responsible manner. Substances and
materials arising from dismantling should be destroyed,
re-used or disposed of in accordance with the regulations
currently in force.
The following table gives a list of materials that may be
®
found in Power Xpert switchgear.
All materials used in the manufacture of the Power
®
Xpert UX switchgear can be recycled. No toxic or
harmful products are generated in the normal use of the
switchgear.
