Safety Considerations

Definitions

72A-1230 Rev. F
The preceding also applies to test sets that have been stored for prolonged
periods.
Safety cannot be overemphasized when working on or around high voltage
electrical apparatus. Companies that generate, transmit, distribute, or utilize
high voltage electricity should, and do, have precise rules for safe practices
and procedures for personnel whose working responsibilities involve testing
and maintenance of the various types of high voltage apparatus, and their
associated lines, cables, and conductors, as well as the associated accessories.
Throughout this manual, reference will be made to testing personnel in certain
general terms which are defined below. These terms apply only to the testing
function of the individuals and not to their professional status, seniority, or
positions within their company's structure or personnel hierarchy. These terms
are:
• Test Set Operator – The person who supervises the test and operates
the M4000 Insulation Analyzer.
• Operator's Assistant * – The person who follows the operator's
instruction in making test connections.
• Safety Observer * – The person who is responsible for observing the
performance of the test, seeing any safety hazard, and giving warning
to crew members.
* The operator's assistant, or the safety observer, may be employed to operate
the extension safety switch and to act as safety supervisor. The operator of the
safety switch should perform no other work, such as recording test data, while
the M4000 Insulation Analyzer is energized.
Two safety switches are provided and are required to be operated in order to
energize the M4000 Insulation Analyzer. The M4000 Insulation Analyzer
generates high voltage and is capable of causing serious, even lethal, electrical
shock. The M4000 Insulation Analyzer should not be operated by a crew
smaller than two people. A larger crew may be desirable under some
circumstances. Regardless of crew size, one person should be designated as
the Test Set Operator and one other as Test Supervisor.
