Putting CPC 100 into Operation
Safety Aspects
We strongly advise you to obey the following legal safety aspects:
– Tests with such high voltages and currents must only be carried out by
authorized and qualified personnel.
– Personnel receiving training, instructions, directions, or education on high-
voltage/current tests should remain under the constant supervision of an
experienced operator while working with the equipment. The instructions
have to be renewed at least once per year.
– The instructions must be available in written form and signed by each person
assigned to do high-voltage/current tests.
Preparations in Substation
Prior to connecting a test object to CPC 100, the following steps need to be
carried out by an authorized employee of the utility.
– Turn off and disconnect the high voltage from the test object.
– Protect yourself and your working environment against an accidental re-
connection of high voltage by other persons and circumstances.
– Verify a safe isolation of the test object.
– Earth-connect and shorten out the test object’s terminals using a grounding
set.
– Protect yourself and your working environment with a suitable protection
against other (possibly live) circuits.
– Protect others from accessing the dangerous area and accidentally touching
live parts by setting up a suitable barrier and, if applicable, warning lights.
– If there is a longer distance between the location of CPC 100 and the area of
danger (that is, the test object), a second person with an additional
"Emergency Stop" button is required.
Note: Before setting CPC 100 into operation and carrying out a test, it is
essential that you have read and understood the section ”Safety
Instructions for CPC 100 and its Accessories” on page 1-5.
Always be aware that all AC and DC output sockets of CPC 100 can
carry life-hazardous voltage potential and provide life-hazardous
currents.
