6. Test procedures
6.1. Testing for the off-circuit condition
The off-circuit condition on the cable side is
tested by means of the capacitive voltage
indicator (pick-off on the outer cone). The
following systems can be used (Fig 6.1.1 to 6.1.5):
• LRM system,
• KVDS system,
• CAVIN system,
• System Wega 1.2 C or 2.2 C
Hazard warning
Observe the instruction manual for the
system used.
• Check the function of the equipment
immediately before use. The optical
display must be clearly visible!
• The sockets of the capacitive indicator
system must never be short-circuited,
except during voltage testing on the
switchgear.

Testing for the off-circuit condition is performed
with a plug-in display unit (design to IEC 61243-5)
at the three pairs of measuring sockets.
Hazard warning
Perform repeat tests on the system in

instance with interface tester KSP.
Observe the instructions for the
interface tester.
6.1.2. KVDS, CAVIN- and Wega systems
Testing for the off-circuit condition is performed
with the display on the unit. No separate display
unit is required.
