SAFETY SUMMARY
The following safety precautions must be
observed during all phases of test set-up, test
hookups, testing, and test-lead disconnects.
Do Not Service or Test Alone
Do not perform test procedures or service
unless another person is also present who is
capable of rendering aid and resuscitation.
Avoid Contact with High Voltage
Because electric utility station environments
contain high voltages and currents, there’s
always the possibility of personal contact with
an unexpected lethal voltages generated by
magnetically induced and/or electrostatic
leakage from nearby live circuitry. When test
units are connected to de-energized ("dead")
lines, regardless of how short these lines may
be, always discharge the lines before
attaching test lead. Because of the possibly
deadly consequences of physical contact with
such lines, engineers and technicians must
always treat electrical equipment and hookups
as though a lethal condition will eventually
occur. Therefore, no matter how unlikely it
may be, never assume anything about the
safety of any test setup.
Ensure the safety of personal by checking
first-hand to eliminate every possible hazard!
Avoid Contact With High-Voltage “Kicks”
Any transformer with many windings turns
and an iron core supports induced magnetic
fields, such that even low-level test currents
produce a magnetic field that, if interrupted,
can produce a high-voltage spike capable of
causing severe injury or death. Accordingly,
its important for personnel safety that test
leads be securely attached to the transformer
terminals to prevent their being accidentally
disconnected during testing. All personnel
are warned to stand clear of the transformer
during all testing. Test technicians should
always ensure that all non-technical personnel
(who may not understand the hazards) be
required to stand clear of all transformers and
equipment during all phases of transformer
testing.
Do Not Modify Test Equipment
Because of the added risk of introducing
additional or unknown
hazards, do not install
substitute parts or perform any unauthorized
modification to the Accu-Trans. To ensure all
designed safety features are maintained, it is
recommended that all Accu-Trans repairs be
performed at Vanguard Instruments Co. or by
an authorized repair-service. Unauthorized
equipment modifications can create safety
hazards and will void the Accu-Trans
warranty.
Follow Exact Operating Procedures
Any deviation from the operating
procedures described in this manual may
create one or more safety hazards, damage
the unit or cause test result errors; Vanguard
Instruments Co. assumes no liability for
unsafe or improper use of the Accu-Trans.
