4.1 Preparations in Substation
• 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.
• 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 the CP TD1 and the area
of danger (that is, the test object), a second person with an additional
"Emergency Stop" button is required.
4.2 Connection
1. Without trolley:
Properly connect the CPC 100 and CP TD1 grounding terminals to
substation ground.
Warning: Prior to connecting a test object to the CP TD1, the following steps
need to be carried out by an authorized employee of the utility.
Warning: Earth-connect and shorten out the test object’s terminals using a
grounding set.
Warning: Make sure to position the test object or CP CAL in the high-voltage
area.
Warning: Never use the CP TD1 without a solid connection to ground with at
least 6 mm². Use a ground point as close as possible to the test object.
