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 will flow through any available ground path.
Rules
Operators should be thoroughly trained to follow all of the aforementioned rules, in addition to
any other applicable safety rules and procedures. Defeating any safety system should be
considered a serious offense with severe penalties such as removal from the Hipot testing job.
Allowing unauthorized personnel in the area during a test should also be dealt with as a
serious offense.
Dress
Operators should not wear jewelry that could accidentally complete a circuit.
Medical Restrictions
Personnel with heart ailments or devices such as pacemakers should be informed that the
voltages and currents generated by the instrument are very dangerous. If contacted it may
cause heart-related problems that a person of good health may not experience. Please have
the test operator consult their physician for recommendations.
