WARNING
Dangers when operating with HV
Special attention and safety-
conscious behaviour is needed when operating HV
facilities and especially non-stationary equipment. The regulations VDE 0104 about
setting up and operation of electric test equipment, i.e. the corresponding EN 50191
as well as country-specific regulations and standards must be observed.
• The VLF Sinus 34 kV generates a dangerous voltage of up to ±24 kV
RMS
during
testing. This is supplied via a HV cable to the test object.
• The test system may not be operated without supervision.
• Operation requires minimum two people whereas the second person must be
able to activate the emergency switch in case of danger.
• Safety installations may not be by-passed nor deactivated.
• To avoid hazardous electric charges of metallic parts in the vicinity, all metallic
parts must be grounded.
• Check whether there are any unsecured live systems or components in the im-
mediate vicinity of the test system which might you or the system might
accidentally come into contact with. This particularly applies to components
which carry high voltage or where the voltage is unknown.
Secure these components using insulating covers. If technical reasons make it
impossible to do this, switch them off or have this action carried out at the site for
the duration of your work after consulting whoever is responsible. Make sure this
is done properly.
