Section 2
Safety
This equipment and the cable to which it is connected are sources of high-voltage
electrical energy. All persons performing or assisting in tests must use all practical safety
precautions to prevent contact with energized parts of the test equipment and related
circuits. Persons actually engaged in the test must stand clear, by at least 3 ft (0.91 m), of
all parts of the complete high-voltage circuit unless the system is de-energized and all
parts of the test circuit are grounded. Persons not directly involved with the work must
be kept away from test activities by suitable barriers, barricades or warnings. Be aware
that impulses applied to the cable will be present at the remote end(s) and any other
exposed part of the cable, usually out of sight of the operator. To avoid inadvertent
contact with hazardous live parts, always ensure that access to all exposed parts of the
cable or connected equipment is restricted, by using suitable barriers or barricades.
§
Safety is the responsibility of the user.
§
Misuse of this high-voltage equipment can be extremely dangerous.
§
The purpose of the test equipment is limited to use as described in this manual. Do
not use the equipment or its accessories with any device other than specifically
described.
§ Never connect the test equipment to energized equipment.
§
Never use the test equipment if there is any possibility that the test equipment or
cable under test is in an explosive atmosphere.
§ A qualified operator should be in attendance at all times while the test equipment is
in operation.
§
The safety ground jumpers and surge ground must be properly connected (refer to
Section 5).
§
Refer to IEEE 510-1983 "IEEE Recommended Practices for Safety in High-
Voltage and High-Power Testing," and follow the applicable safety
recommendations.
§
Observe the safety warnings marked on the equipment.
Treat all terminals of high-voltage power equipment as a potential electric shock hazard.
There is always the potential of voltages being induced at these terminals because of
proximity to energized high-voltage lines or equipment. Always use a safety grounding
stick to ground the high-voltage conductor. A safety ground jumper must then be
installed between the high-voltage conductor and ground of the cable under test. The
ground connection must be the first made and the last removed.
