An interlock should be considered to be a safety back-up feature. An interlock should not be
regarded as a substitute for adequate safety rules and proper operator vigilance.
2.1.2.2 Grounding of the high voltage output
A temporary ground should be applied to the high voltage output when the circuit has been de-
energised using the earth stick provided. When connections are made, or disconnected, the
circuit either side of the connection should be grounded first. Extra earth sticks are available
from T&R Test Equipment as an optional accessory.
If the test circuit includes capacitors, each capacitor should be grounded separately before
connections are made or broken. In the case of capacitors connected in series, the intermediate
terminals should also be grounded.
It is good practice for all capacitive devices to remain short-circuited when not in use.
2.1.2.3 High voltage connection
The HV connection to the test object must be made securely to the test object. Suitable stress
relief components should be used where required to keep electrical stresses within acceptable
limits.
2.1.2.4 High voltage output clearances
The high voltage output from the unit is from a screened cable with an un-screened termination,
and adequate clearances must be maintained between the following parts and any other
conducting object (whether earthed or not):

HV output connection

Non-screened part of output cable (between the bulge in the cable and the output clip)

Non-grounded parts of test object
Any part of the test object not connected to earth should be considered live at the test voltage
potential.
Particular attention should be paid to clearances between any parts of the test object at test
voltage potential and the test enclosure or barriers.
