test station. Signs should be posted: "DANGER - HIGH VOLTAGE TEST IN PROGRESS -
UNAUTHORIZED PERSONNEL KEEP AWAY."
Work Area
Perform the tests on a non-conducting table or workbench, if possible. If you cannot avoid using a
conductive surface, be certain that it is connected to a good earth ground and the high voltage
connection is insulated from the grounded surface.
There should not be any metal in the work area between the operator and the location where
products being tested will be positioned. Any other metal in the work area should be connected to
a good ground, never left "floating".
Position the tester so the operator does not have to reach over the product under test to activate
or adjust the tester. If the product or component being tested is small, it may be possible to
construct guards or an enclosure around the device to be tested. Construct the guards of a non-
conducting material such as clear acrylic, so that the item being tested is within the guards or
enclosure during the test. If possible, the guards or enclosure should also contain safety switches
that will not allow the tester to operate unless the guards are in place or the enclosure closed.
Keep the area clean and uncluttered. All test equipment and test leads not necessary for the test
should be removed from the test bench and put away. It should be apparent to both the operator
and to any observers, the product that is being tested and the product that is waiting to be tested,
or has already been tested.
Do not perform Hipot tests in a combustible atmosphere or in any area where combustible
materials are present.
Power
Dielectric Voltage-Withstand Test Equipment must be connected to a good ground. Be certain that
the power wiring to the test bench is properly polarized and that the proper low resistance
bonding to ground is in place.
Power to the test station should be arranged so that it can be shut off by one prominently marked
switch located at the entrance to the test area. In case of an emergency, anyone can cut off the
power before entering the test area to offer assistance.
1.3.3 Test Operator
Qualifications
This instrument generates voltages and currents that can cause harmful or fatal electric shock and
must only be operated by a skilled worker trained in its use.
The operator should understand the electrical fundamentals of voltage, current, and resistance.
They should recognize that the test instrument is a variable high-voltage power supply with the
return circuit directly connected to earth ground, therefore, current from the high-voltage output
